The ultimate guide to building a mobile app
Got a great idea for an app? Need a new way to grow your business? We tell you everything you need to know about building a mobile app in 2020.
Mobile App Development is the creation and development of phones, tablets, personal digital assistants, and other devices that have operating systems. It involves creating software applications for the devices, such as games, utilities, and sometimes even simple to-do lists. These applications are created using programming languages such as HTML5 and JavaScript, which allow developers to create a good user interface. Mobile App Development requires both specific and hard skills from developers, from debugging existing applications to creating entirely new ones.
A great benefit of having a Mobile App Developer on your side is the knowledge and experience they can provide to make your business grow. In addition to creating mobile apps that are good for the user experience, Mobile App Developers can help you with backing up the data from your application securely, modifying an existing app to meet new requirements, troubleshooting any current issues in your application, setting up a server for your application and so much more.

From 372,490 reviews, clients rate our Mobile App Developers 4.9 out of 5 stars.I’m days away from releasing a brand-new Android app and need a person with at least 12 Gmail accounts to help test it either on your phone or laptop. Once we start, I’ll share the APK through a Gmail-accessible link, a concise usage guide, and a feedback template. Here’s what I’m after: • Install the build on your everyday Android smartphone and, if you have one handy, a tablet as well so we can see how the UI scales across form factors. You can also open it on an emulator or desktop tool for extra checks, but that’s optional. • Explore every screen, trigger every button, and deliberately push each workflow until you’re certain it behaves—or misbehaves. • Capture notes on the three areas I care about most: User Interface quirks, C...
I have a small batch of Viber voice messages—fewer than ten—that I can no longer reach because Viber has cleared them to free up storage. Your job is to locate those files in the Viber backup or on-device storage, extract them without loss, and convert each one to a single, clearly audible MP3. Security is critical: I’ll provide temporary access, and I expect you to work on a local, offline environment, keep logs minimal, and delete every copy once I confirm receipt. Let me know the method you normally use (e.g., SQLite browsing, Viber desktop cache extraction, mobile root/Jailbreak with ADB/iTunes, etc.) and how you keep user data private. Deliverables • Up to 10 recovered voice messages in MP3 format • Brief note on the extraction steps you took so I c...
I already have a working Android Studio project and I’m ready to improve it in two areas: 1. Login flow • Replace the current entry screen with a fresh login page that includes a country picker dropdown showing the national flags for Lesotho (+266), South Africa (+27), Eswatini (+268), Tanzania (+255) and Uganda (+256). • When a user taps a country, its dial code must fill the phone-number field automatically. • The screen has to be fully coded in Java or Kotlin—no static mock-ups. 2. In-app shop • Beyond login, I need a product-based shop featuring unlimited item listings, a cart and a checkout flow. Think of a clean catalogue view, add-to-cart button, quantity updates and an order summary screen. Deliverables • Updated And...
I’m seeking an experienced development team to build a retail platform under my own brand, with all the features of Shopify and Lightspeed Retail, plus custom functionality. I need a software platform with all the features of Shopify, Shopify POS, and Lightspeed. We will use it across our businesses and sell subscriptions to other companies, each with a separate, secure account. Required capabilities: Ecommerce, POS, offline selling, inventory, purchasing, shipping, returns, wholesale, and multi-store management. Fingerprint clock-in/out with notifications. Camera integration and cash drawer opening/closing alerts. Employee logins showing only their own sales, with management-controlled reporting dates. Live sales updates with timestamps down to the second. Inventory alerts...
i need a tradingview pine script to make an indicator for the following: 1. Timeframe Levels are calculated only from H1 (1-hour) candles. Use RTH H1 data even if the chart is on a different timeframe (request the 1H series). 2. Session RTH only: 9:30 AM – 4:00 PM New York time. Ignore extended hours / overnight completely. Start aggregation at the regular market open. 3. How a Level is created (“confirmed”) Look at consecutive completed H1 RTH candles. A candle is bullish if close > open, bearish if close < open. A doji (close == open) breaks the sequence. When the direction flips (previous bearish → current bullish, or previous bullish → current bearish): Draw a horizontal level at the open of the current (color-changing) candle. Only the open of ...
I’m taking my 3D fantasy survival game from prototype to a polished, playable slice in Unity. Players will harvest resources, craft gear, fight AI-driven enemies and explore an open world dotted with towns, and I need solid systems— not just placeholders— to make that loop feel great. What I still need: • Core gameplay loops: resource harvesting, inventories, crafting stations and responsive third-person combat. • AI behaviour: patrolling, chasing and cooperating enemies, plus simple civilian NPC routines, all running on Unity NavMesh or a behaviour-tree solution you’re comfortable with. • Environment building: sculpting terrain, lighting and weather, then turning my reference images into believable towns and set dressing that invite exploration....
I have an app Biased Sports Picks and we have a test app for launch in the Google Play Store and I need fresh eyes on it for a full two-week stretch. You will install the current production build, open a free account, and use the core features every day so I can see how the app behaves under real-world, repeat traffic. Here is what I need you to do daily for 14 consecutive days: • Making picks – choose at least one match-up each day and submit it. • Viewing standings – open the leaderboard, scroll, and note whether your latest pick updates correctly. • Leaving comments – drop a line in the global chat after you place a pick. • Browse posts/articles and general content. • Report any errors, crashes, slowdowns, or odd UI behaviour through ...

I want to turn my concept “Mimujer y yo” into a fully functional mobile e-commerce app. The core requirement is a smooth shopping-cart experience that lets customers add, edit, and remove items before checkout. I already know the app’s main goal—selling products—so I need someone who can take that objective and translate it into an intuitive, secure mobile application. Design the user flow around browsing a catalog, tapping an item, and moving it straight into the cart. Payment processing, account creation, and order confirmation screens should all support that flow without friction. If you have existing modules for product search, filters, or user reviews, let me know; they could become the next phase, but right now the shopping cart is the must-have deli...

I’m ready to take our platform from beta to production and need a developer who can set up all live-side services, modernize the Android app, and shape a revenue strategy that works from day one. Scope of work • Infrastructure – Spin up a reliable, scalable environment that supports business profiles, captures and stores video & chat inquiry files, and hosts short marketing videos. All media assets must route to Wasabi S3 buckets with usage metering, threshold alerts, and a simple dashboard or scheduled report so I can track total storage in real time. • Android app – Extend the current codebase to surface business communications, enable profile management, and add a lightweight scheduling module. New UI flows should feel native, respect existing design...

I have an existing mobile app with separate Swift (iOS) and Kotlin (Android) codebases and I need a handful of targeted adjustments applied to both sides. Nothing ground-up—just concise edits, small feature tweaks, and a couple of bug fixes that surfaced during recent testing. The work will involve: • Updating the native Swift and Kotlin files where required • Ensuring parity between the iOS and Android builds so the changes behave identically • Compiling and testing each platform, confirming that new code doesn’t introduce regressions • Supplying the updated source and a brief change log so I can follow what was modified All code must compile cleanly with the current Xcode and Android Studio versions I’m using, and TestFlight / internal ...
My new mobile app is almost ready to hit the stores, and I have a short window to generate real traction. The entire push will centre on Facebook and Instagram, where the target audience already spends most of its time. I need a full-service social media marketing roll-out that drives one key metric: downloads. Scope of work • Strategy – map out a 4-week launch plan that sequences teaser, launch-day, and post-launch content. • Creative – design a mix of short-form videos, scroll-stopping images, and punchy text posts aligned to each stage. All assets must be optimised for Facebook Feed, Stories, Reels, and Instagram counterparts. • Paid amplification – set up and manage Facebook Ads Manager campaigns with clear download-tracking via App Install objec...

I have several stand-alone AdMob accounts that I’m ready to let go of—there are no Google Play apps bundled with them, just the clean, verified AdMob properties. What I need is a savvy freelancer who can turn these assets into attractive listings, place them on the right marketplaces or communities, and guide interested buyers through to a successful hand-over. Here’s the flow I’m envisioning: you draft clear, compelling sale copy for each account, highlight the compliance status and earning history I provide, publish or post in the channels you know will reach serious buyers, and manage communication until an agreement is in place. Once a buyer is confirmed, you’ll walk us both through Google’s official transfer procedure to be sure the account switche...
I need an Android service that hardens my phones and tablets by tying their safety to a Samsung Watch. Core workflow • While the watch is paired and within 50 m (GPS), the device behaves normally. • If the watch travels beyond that radius, a countdown starts (length to be parameterised in settings). When the timer expires, the handset performs a full factory reset. • The same timer-then-reset sequence is triggered whenever the watch is powered off or its Bluetooth connection is deliberately severed. • A unique, user-set PIN must be entered on the system lock screen to cancel the reset once it has begun. No PIN, no mercy—reset proceeds. Technical notes • Must run on Android 10 and above without root. • Should recognise any Samsung Watch that...
The core functionality of my iOS app is solid, yet the overall look and feel are overdue for a refresh. I want the design and layout tightened up—cleaner screens, consistent typography, fresh spacing, and smoother transitions—so users instantly sense a modern, polished experience. I coded everything in Swift with UIKit and Auto Layout constraints; the project is Xcode-ready on a private Git repo. Your task is to rework the existing views (roughly a dozen) without touching business logic. Think adaptive layouts, refined colour palette, updated assets, and a coherent visual hierarchy that scales elegantly from iPhone SE to the latest iPad Pro. Because I need this ASAP, I’ll be reviewing pull requests daily and merging in stages. Expect quick feedback loops. Deliverab...
I’m creating a mobile-only platform that lets users book a “rental boyfriend” and spend time together entirely online. The experience revolves around three live, in-app date modes: HD video calls, interactive chat games, and synchronized movie streaming. I need a developer (or small team) who can take the idea from concept to a polished Android and iOS release, including secure sign-up, a scheduler for sessions, real-time payments, and the media engines that power those three date modes. Smooth video, lag-free gameplay, and perfectly synced movies are the success benchmarks. Deliverables • UX/UI mock-ups approved in Figma (or similar) • Fully functional iOS & Android apps with the three virtual date features live in prod • Admin dashboard to...
Writing Allow non-Indian women and non-Indian languages during signup. Use for recharges using the Gmail user ID Recharges are in USD: 1, 2, 3, 4, 5, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, and 100. Once a recharge is successful, the wallet balance should be multiplied by 80. Non-Indian men should only have access to Online, Chat, History, Matches, Wallet, and Profile tabs. For men and women, the tabs should be available as specified. Non-Indian women will not earn money. Non-Indian men and non-Indian women will only be available for chat and recharges. The Infinity Recharge pop-up should appear when a user's balance is less than ₹4. For all men's tabs except Profile and Wallet, apply the specified restrictions. When non-Indian women chat with non-Indian men, non-Indian ...
I want to build a brand-new social media application exclusively for Android. The goal is to launch a functional prototype that lets users create accounts, post content, interact through likes and comments, and receive real-time push notifications. I need a developer who can handle the full Android stack—from designing clean, Material-styled screens to writing well-structured Kotlin/Java code and integrating a scalable backend (Firebase, Supabase, or a solution you recommend). Key expectations • Account creation and secure login (email, Google, or phone) • User profiles with editable bio and avatar • Infinite scrolling feed for text, photo, and short-video posts • Like, comment, and follow mechanics • Push notifications for follows, likes, and commen...
I’m looking for someone to hack my own device and my Instagram account More details: What type of device do you need to access? Smartphone What operating system does the smartphone use? iOS What objective are you trying to achieve by accessing your iOS device? This question was skipped by the user
My Aspera handset is stuck behind Google’s Factory Reset Protection after I forgot the screen PIN and lost access to the registered Gmail account. I haven’t tried any technical work-arounds yet, so the phone is still exactly as it was when the FRP screen appeared. The warranty period has already expired, but I can supply a scanned proof of purchase to demonstrate legitimate ownership. I want the lock lifted so the phone powers on normally and lets me register a fresh Google account. Whether you achieve that through ADB commands, SP Flash Tool, custom recovery, or another proven Android service method is up to you; I only need a safe solution that won’t hard-brick the device. Acceptance criteria – once you say the job is complete I will: • boot the phone wit...
I already run an e-commerce web application and now want the very same experience packaged as a mobile app with Expo. All screens, flows, and assets exist inside the current web build, so the visual design and user journey are ready to be replicated—no fresh UI work is required. Your job is to: • rebuild the app in React Native using Expo, mirroring the existing functionality of the web version; • generate the release builds (.aab for Google Play, .ipa for the App Store); • guide the apps through store submission until they are approved and live. I will supply: – full access to the production web app and its API endpoints; – all graphic assets, icons, and brand guidelines; – required developer-account credentials for both stores. Delive...
Project Title Develop a QR-Based Instant Document Printing Platform for Multiple Shops Project Overview I am planning to launch a QR-code-based instant document printing network in Hyderabad, India. The objective is to install printing facilities at multiple existing shops, allowing customers to upload documents from their mobile phones, pay online and get their documents printed instantly. Customers should not need to install a mobile application. They should simply scan a QR code displayed at a shop, open a mobile-friendly webpage, upload their documents, select printing options, make payment and collect their printouts from the respective shop. Initially, the network will have 10 locations, with a combination of company-owned and partner-owned printers. The platform should be desig...

I’m creating an “online rental boyfriend” experience where the sole focus is real-time chat companionship. The service must be accessible across the three channels I rely on most: • Website • Mobile app • Social media integrations Your job is to set up the actual chat layer—user registration, profile management, secure messaging and presence status—so clients can hop in and start a private conversation with their chosen companion from any of the outlets above. A consistent look-and-feel is important, but I’m happy to hear framework recommendations. React (web) plus React Native or Flutter (mobile) and a Node.js/WebSocket backend are all fine; if you have a better stack that still delivers latency-free messaging, pitch it. Key ex...
I’m ready to turn a fresh social-networking concept into fully-functional Android and iOS apps. At its core the product needs familiar community staples—rich user profiles, a real-time messaging system and a dynamic activity feed—wrapped in a modern UI that feels lightning fast. Beyond the basics, two elements are non-negotiable: • Short-form video support so members can share “shorts” fluently from the camera or gallery. • Solid monetization paths (think in-app purchases, ads, tipping or a hybrid you propose) so the platform can sustain itself from day one. I’d also like members to create and promote events inside the app, with RSVP tracking that feeds straight into their activity streams. You can work in native Swift/Kotlin or a cros...
I have a nearly-finished mobile app for both iOS and Android, but several tasks are still blocking release. The codebase is stable overall; I simply need an experienced developer who can jump in right away and tackle three areas: squashing the last few bugs, adding a couple of small features, and tightening performance where things still lag. The scope is intentionally lean and should be quick for someone familiar with typical Swift/Kotlin or React Native/Flutter stacks (the exact framework can be confirmed once we connect). I will share the private repo, a short ticket list, and the current build so you can reproduce the remaining issues and measure progress. Deliverables • Clean pull requests that close each open bug ticket • Fully functional implementation of the listed ...
Aapko jo bhi banvana hai bas Idea btoa requirement. Btao feutre btao
My Android- and iOS-ready app is almost launch-able, but a handful of loose ends still stand in the way. Top priority is the media workflow: right now images refuse to upload, refuse to display, or break when the file type isn’t ideal. I need that entire path—from picking a photo to seeing it render perfectly in the UI—bullet-proof across both platforms. While you are inside the codebase, I would also like full text-editing capability exposed so future copy changes can happen without another round of builds, plus a few small functional tweaks that have been lingering on the to-do list. Deliverables • Image pipeline repaired: upload errors eliminated, common formats (JPG, PNG, HEIC) accepted, and pictures rendered crisply in every view. • In-app text & i...
I’m at the early stage of building an AI-powered business application and I’m looking for a developer who can turn my rough concept into a working web and Android prototype. My current focus: • Business Apps that solve day-to-day operational pain points. • A core User Management module where admins can create, edit, and deactivate users, assign roles, and track usage. What I need from you 1. Translate my idea into a clear technical plan (tech stack suggestions, AI service recommendations, and basic architecture). 2. Build a simple yet functional prototype: login/registration, role-based dashboards, and AI-assisted features such as smart data entry or automated reminders. 3. Walk me through the code and deployment steps so I can continue enhancing the pr...
I am building a mobile-only platform where users can hire a “rental boyfriend” for three clear purposes: companionship at events, emotional support through in-app chat, and personalised city tours. The entire experience must live inside a polished iOS and Android application. Core flow • New users come in through social-media login (Facebook, Google, Apple, etc.). No other sign-up methods are planned. • After onboarding, they browse detailed profiles, availability calendars, and service descriptions. • Bookings are placed, paid, and confirmed within the app, with real-time chat opening automatically once a reservation is accepted. • For tour guide sessions, the app should use location services so the renter can share meeting points and live directio...

I want to launch a lightweight, app-style website that runs smoothly on Android devices and focuses solely on text-based data entry and ongoing content editing. The goal is to give authorised users a fast, uncluttered interface where they can create new records, update existing ones, and manage everything from an Android phone or tablet without juggling desktop screens. Key workflow • User logs in, chooses the relevant form, and types or pastes text. • Each submission is saved to a backend database and instantly retrievable for future edits. • Simple search and filter tools let users locate a record in seconds. A responsive layout that feels native on Android is essential, and the design should keep typing efficiency front-and-centre (large tap targets, auto-save c...

I want a seamless way to interact with ChatGPT on my iPhone so it can handle the everyday tasks I normally juggle myself. The assistant must be able to: • Read incoming Messages and draft/send replies on my behalf • Add, edit, or cancel Calendar events in the native Calendar app • Create, modify, and mark off items in the Reminders app Both voice and text interaction matter to me. If I’m walking, a simple spoken request should trigger the same flow as typing inside the app. You’re free to lean on Siri Shortcuts, a custom SwiftUI interface, or any other iOS-approved method—as long as the experience feels native and secure. I’m happy for you to leverage the OpenAI API, Core ML, CallKit, or Notification Service Extensions where helpful, but keep...
I’m ready to move my Android application from internal builds to a wider release on Google Play, but I’d like a fresh, systematic round of testing first. The build is already uploaded to the Google Play Console (closed track), so you’ll be added as a tester the moment we start. Scope • Functionality – Every feature should behave exactly as intended across a representative range of devices. Please focus on feature-by-feature checks, real-world usability flows, and compatibility between Android versions. • Performance – I’m specifically looking for clear data on load times, battery drain during typical use, and memory consumption under stress. • User Interface – Flag broken layouts, alignment issues, unreadable text, or anything...

I’m looking for a fill-able PDF that I can open on my iPad during new-construction inspections. The file must already contain roughly 50 common checkpoints I deal with every day, yet still let me insert additional rows when an unusual item pops up. For each line I need two things: a simple checkmark box that instantly tags the item Approved or Disapproved, and a photo placeholder that lets me drop in (or capture) pictures on site. The photo should sit right beside its line so everything stays in context when I review the report later. Because this has to run smoothly on an iPad, please build it with standard Acrobat-compatible form fields—nothing that relies on a separate app or web connection. Auto-expanding text areas for notes and a clean, printable layout will round o...

We need an experienced engineer or accountable team to perform final hardening, verify release readiness and complete a controlled release. SYSTEM - Two apps: customer-facing and sales/service. - One shared Node.js/Express + PostgreSQL backend with Stripe. - A thin React admin portal using the same backend. - React Native/Expo mobile code is part of the existing system. - Existing source code, automated tests, CI and written release procedures will be provided under NDA.

I’m building an “online rental boyfriend” service and need a mobile app developed from the ground up for both iOS and Android.
