From 63,495 reviews, clients rate our Mobile Developers 4.9 out of 5 stars.We currently have a Android App where we have changed the interactive line animation, this built in Java and Android XML. We have also added an icon category screen with clickable icons and we also have also a topic list screen which appears when you click a category icon on the catefory screen, you can check these pages and feature out when you first open the Android application and click the 'Tap to continue' button and log in, the first screen is the category screen with clickable category icons, then when you click a category icon the second screen is the list of topics for that category and lastly when you click a topic you get the line screen and the interactive line animation happens when you click any of the purple lines no this screen. The work that we need is we need ...
I want to turn key geometry topics into a series of self-contained, interactive exercises that hold the attention of 13- to 18-year-olds and guide them from basic definitions through applied problem-solving. The material will live online, so everything must run smoothly inside a modern browser on laptops, tablets, and phones without extra plug-ins. Each exercise should let students manipulate shapes, drag-and-drop measurements, or toggle construction steps, then receive instant feedback that explains both correct and incorrect choices. Where possible, visual hints and short, in-context explanations should replace long text blocks; the goal is “learn by doing.” Deliverables • A collection of interactive geometry activities packaged as HTML5/JavaScript (or another lightw...
I run a small clinic and need a straightforward mobile application that lets my team capture, store and pull up a patient’s complete medical history at any moment. The heart of the build is a structured medical-history module linked to a prescription writer, so a doctor can open a chart, review past notes, add today’s findings, then generate and save a new prescription—all from one screen. The app has to work smoothly on modern smartphones, store data securely on-device first, and give me an easy way to back up or export records (PDF for individual visits and CSV/JSON for bulk data). A quick search by name, phone number or patient ID is critical because we often look up a file while the patient is sitting in front of us. Appointment scheduling is not a must-have right no...
Based on the image you sent from the Freelancer app ("Tell us what you need done"), the text you should type into that empty box depends on what kind of project you want to post. Here are a few options you can copy and paste depending on what you need: —————————— Option 1: If you want to hire someone to edit a photo (like the church photo you mentioned earlier) I need a professional photo editor to edit a church photo. I want you to remove the background trees, replace them with a nice dramatic sky, enhance the lighting and colors, crop it nicely, and deliver a high-quality final image. —————————— Option 2: If you want to hire a Graphic Designer (Logo...
I have a straightforward job: design 5–6 clean, responsive screens in Figma that will look great on both mobile phones and tablets. Each screen is mostly text-based—think H1/H2 headings, short paragraphs, a form field or two, and clear call-to-action buttons. No complex dashboards or animations, just polished layout, good hierarchy, and consistent spacing. Here’s what I need from you: • A single Figma file with all screens organised in frames for mobile and their tablet counterparts. • Styles and components set up so I can tweak colours or text later without breaking the layout. • Export instructions or assets only if any custom icons or illustrations are added. No agencies please. Budget is 1200 rupees.
I need a complete Android-only mobile app built from the ground up for my project, Jamzith ja. The core idea is defined, yet the feature set still needs to be refined and transformed into an intuitive, production-ready experience. I’m looking for a developer who can guide the process end-to-end—brainstorming UX, translating it into clean Kotlin or Java code, and delivering a signed release build on Google Play. Key deliverables • Interactive wireframes and UI designs approved before coding begins • Native Android app coded with modern SDK practices and a modular architecture • Integrated analytics and crash reporting, plus responsive layouts for phones and tablets • Ongoing commits to a private Git repo and clear documentation for future maintenan...
Mobile App QA Tester Needed Looking for an experienced QA tester to thoroughly test our home-services platform before launch. The platform includes: • Customer App • Service Professional App • Admin Panel Scope: Complete manual testing, end-to-end user flows, booking & payment flows, UI/UX issues, edge cases, bug reporting with screenshots/videos, and re-testing after fixes.
I will send link just to download app
I need help wiring up a small but very specific feature in my Android app: when a user touches and holds any saved text clip, it should toggle a “pinned” state; pinned clips stay forever, while anything left un-pinned is automatically purged 60 minutes after creation. The core UI is already in place; what’s missing is the persistence logic and the timer-based cleanup. I’m working in Kotlin with the current stable Android SDK and Jetpack libraries, so I’d like the solution to slot neatly into that stack—Room (or another lightweight local store) for persistence, a WorkManager or Coroutine-based job for the hourly sweep, and straightforward state handling so the pin icon reflects changes instantly. Acceptance criteria • Long-press marks or unma...
Subject: Senior Full-Stack Mobile Engineer for Luxury Multi-Language Ride-Hailing Platform (Flutter / React Native) Hi Developers I’m launching a high-end private ride-hailing service tailored for a specific regional market, and I’m looking for an elite mobile developer to bring it to life. I’m not interested in a messy prototype or a generic, clunky template. The vision is to build something that feels genuinely world-class—fluid, visually stunning, and as effortless to use as Uber, but with a sharper, more refined aesthetic. The interface needs to be clean, intuitive for everyday users, and completely frictionless from the moment someone opens the app to when they complete a ride. What We Are Building: The Passenger Experience: A gorgeous, minimalist UI with a ...
Run a quick end-to-end check of our live Hutch mobile service using a Hutch SIM physically located in Sri Lanka.

The flow is simple: 1. Subscribe to the service through one of the live portals: 2. Immediately unsubscribe. 3. Save the raw, unedited recording. Acceptance criteria • Network indicator clearly shows Hutch at all times • Full subscription journey, each SMS sent/received, and the unsubscription confirmation are visible without cuts or skips • Raw video file is shared, plus a brief two-to-three-sentence note stating the time ...

I need fresh eyes on my Android app to track down stubborn “App Not Responding” crashes. To reproduce the issue reliably you will log in with several different Gmail accounts, so please come prepared with at least three active addresses. Here is what I am looking for: • Install the current APK on a real Android device (not an emulator). • Use each Gmail account to sign up, navigate through every screen, and trigger heavy-use scenarios that might freeze the interface. • The moment the app hangs, capture a full logcat trace, note the steps that led up to it, and grab a quick screen-recording if possible. • Repeat until you can no longer reproduce the freeze or you have isolated a clear pattern. Deliverables 1. A concise test report listing every ANR...

I am building a mobile-first e-commerce application whose initial release focuses purely on a browsable product catalog. This is a mobile app project, not a responsive website, and the core objective right now is to give users an attractive, fast, and searchable catalog experience. What I need from you is an MVP that runs smoothly on both iOS and Android (React Native or Flutter are both fine). Because it is strictly catalog-only at this stage, there is no shopping-cart flow or payment gateway to wire up, but please lay the architecture out so those elements can be added later without a full rewrite. Key areas I will review: • Clean, modern UI that matches standard e-commerce patterns • Efficient data handling for categories, variants, and images • Simple admin o...

We have an existing live travel web application built on a low-code backend platform. The backend, authentication, APIs and core business logic are already functioning. We are looking for an experienced contractor to redesign and rebuild the frontend experience only, while preserving the existing backend and application functionality.

I’m looking for an experienced Android developer to build a grocery delivery application from the ground up. The app should run smoothly on Android phones and tablets, guiding a customer from product browsing all the way to order confirmation and delivery. At minimum, the flow needs to cover browsing a live catalogue, adding items to a cart, scheduling or requesting immediate delivery, and checking out securely. I’m open to your recommendations on tech stack—whether that’s native Kotlin, Java, or a cross-platform framework that still produces a polished Android build. Clean architecture, modular code, and thorough inline documentation are very important because my in-house team will take over maintenance once the project is live. Please include examples of previou...
I have the layout sketched and the content ready; what I need now is a motivated junior developer who can turn those wireframes into a lively, responsive website. The build will rely on solid HTML & CSS structure and clean JavaScript, but the real focus is on bringing the pages to life with smooth, eye-catching animations—think subtle micro-interactions as well as larger, scene-based transitions. Here’s how we’ll work together: I’ll supply the page designs, brand assets, and a clear animation brief. You’ll translate that into semantic markup, modern CSS (Flexbox/Grid), and JavaScript-driven effects. If you already play with GSAP, ScrollTrigger, or similar libraries, that’s a plus, yet vanilla JavaScript solutions are perfectly welcome as long as per...

I’m launching a new fashion and accessory line and need a fully-functional Shopify store that feels as modern and sleek as the pieces themselves. The layout should be visually bold yet intuitive, guiding shoppers from the first hero banner straight through to checkout without friction. Key experience features are non-negotiable: shoppers must be able to filter and sort products by style, size, colour and price; leave and read authentic customer reviews right on each product page; and save favourites to a personal wishlist they can revisit later. All of this has to remain lightning-fast on mobile and desktop alike. Behind the scenes I’ll need the theme coded cleanly in Liquid, SCSS, and JavaScript so future edits are easy. Standard Shopify payments, shipping zones, automat...

I’m looking for a skilled developer to build a brand-new mobile application from the ground up. This is a pure software-development engagement focused specifically on the mobile space, and I’m open to discussing whether we target iOS, Android, or launch on both simultaneously—please outline what you recommend and why. Here’s what I need: • End-to-end coding of the app, including a clean, intuitive user interface. • Integration of any essential APIs or back-end services you feel are necessary for a smooth experience. • Source code, build instructions, and basic documentation so I can maintain or extend the project later.

I need someone physically located in Sri Lanka with an active Hutch SIM to run a quick end-to-end check of our LIVE mobile service. The task is straightforward: use any modern smartphone—Android or iPhone, your choice—to subscribe to the service, then immediately unsubscribe, capturing the whole journey on video so I can see each screen and SMS confirmation. Please make sure the recording clearly shows: • the network indicator proving you’re on Hutch • every tap or SMS you send/receive during subscription • the successful unsubscription and final confirmation message When you’re done, send me the raw video file plus a brief note (two-three sentences) confirming the time of testing and whether everything behaved as expected. I’d like to...
I want a lightweight, ad-free Android application that lets me look up UP Bhulekh land-records from my phone. The scope is deliberately small: the only in-app action is to search records by owner name and show the matching result exactly as it appears on the official site. A minimalist interface—logo, single search field, and a clean results screen—is all I need. You may implement it in Flutter or in native Android (Kotlin/Java). Under the hood you can either wrap the official website in a well-behaved WebView or call the public endpoints directly; whichever route you choose, the experience must stay fast and free of pop-ups or banners. No Play Store deployment is required. Just hand over: • A signed, install-ready APK • The complete, readable source code with basic...
There’s a shooter-style mobile title live on both Android and iOS and I need fresh eyes on every part of the experience. If you own a reasonably recent phone or tablet and can stay connected to Wi-Fi or 4G for extended play sessions, I’d like you to install the current build, play through the early, mid and late-game loops, then share detailed, actionable comments. Please include your device model, OS version and the approximate number of hours you can dedicate within the first week so I can plan the testing window.
