    I already have the full source code for a driver-facing mobile app. What I need now is a quick end-to-end polish: • Comprehensive testing on both iOS and Android—covering core functionality as well as performance under typical driver workloads (real-time GPS updates, push notifications, background operation, low-signal areas). A concise report of any defects and the fixes you apply must be included. • Creation of release-ready builds: one signed APK and one signed IPA. I will provide any keystores, certificates, or Apple provisioning profiles you require; if something is missing, guide me through generating it. • Private distribution. For iOS the app must appear in App Store Connect as an unlisted or Business-Manager/private app so only my drivers with a suppl...

    I want to move more products by giving customers a fast, convenient shopping experience on their phones. The task is to design and build a full-featured mobile application—iOS and Android—that removes every barrier between browsing and purchase. A friction-less checkout flow, secure payment gateway, push notifications for timely promotions, and in-app analytics to track conversions are non-negotiable because the sole metric for success is increased sales. Visuals must load quickly, feel intuitive, and align with existing brand colours and voice. If current back-end APIs for inventory and orders can be reused, great; otherwise an API layer will be part of the scope. Please suggest the tech stack you believe will deliver the best performance and lowest maintenance (Flutter, Reac...

    I’m building a dedicated mobile app that helps athletes strengthen their mental game. The core of the product is a 90 question assessment, a individualized 20 week program, a library of structured mental-performance exercises paired with a robust progress-tracking system so users can see how their focus, confidence, and resilience improve over time. I need a manual and AI assisted generation system for the assessments, program and activities. It also needs portals for the trainer, athletes, parent, and coaches. The app has to launch on both iOS and Android from a single codebase, so I’m happy with Flutter, React Native, or another cross-platform stack you’re comfortable with, provided it delivers native-level performance.

    I need a full-featured ride-sharing and booking app designed for individual drivers.

    Freelancer should have arabic language & quran knowledge. I would like a modern, cross-platform Islamic prayer app that brings together the core daily tools Muslims rely on and the personalisation options many of us have been asking for. The foundation is straightforward: accurate prayer-time notifications synced to location, an easy-to-use Qibla compass, and the full Qur’an with side-by-side translation. Beyond those essentials, I want the richness found on the Dua & Azkar site to be woven in. That means clearly organised dua categories, scheduled azkar reminders, and a quick “bookmark” tap that lets users save favourite verses or supplications.

    Operational Intelligence Platform for Foreign Trade "Total visibility. Anticipated decisions. Operation under control." The Problem Foreign trade managers face the daily challenge of tracking dozens of simultaneous processes distributed across different teams and operational areas.

    I’m creating Hollow Facility, a 1-6 player co-op horror game in which a self-aware AI—The Warden—observes everything the group does and adapts in real time. The priority is unmistakable, sustained horror: players should feel that every choice is being judged by a living presence that learns, anticipates, and punishes predictable behaviour. Here’s what I need from you: • A concise Game Design Document that explains core loops, progression, and how the AI gathers data and mutates encounters on the fly. • A playable prototype (Unity or Unreal—whichever you’re fastest with) showing one small section of the facility where The Warden can: – track basic player actions (noise level, item use, time spent hiding) – adjust lighting...

    I’m looking for a developer to build a website with a simple skill-based game connected to a leaderboard and prize competitions. The idea is: * Users can enter competitions to win prizes (e.g. iPhone) * Everyone gets 1 free entry try * To get more entries, users must play a skill-based game that costs x amount Game examples: * Estimation game (e.g. guess how many items are in a jar) * Precision/timing game (e.g. tap as close as possible to a target) Each game gives a score based on accuracy, and the winner is the person with the best/closest score (not random). What I need: * Website (mobile + desktop) * User accounts (login/signup) * purchase integration of something safe and reliable like Yoco) * Simple game(s) built into the site * Leaderboard system showing top players *...

    I have an idea for a fairly simple app design. fitness based. totally fine with a browser based application initially if feasible for real world testing before getting into any actual app store applications. essentially i would need to be able to upload csv style formats for workout routines and have the app help navigate the progression. Based on certain criteria the app would automatically load the days workout and suggest weight, rep ranges, when to add reps/weight, etc. would also need to be able to serve as a log potentially with export features but that is secondary. really a progression tracker

    I’m ready to get my clothing label online with a sleek, mobile-first Shopify store that echoes the clean feel of Nike and Zara while staying true to our own pastel colour palette. The build must cover: • A visually engaging homepage that immediately tells our brand story. • Product pages with size/colour variants, stock control, and crisp imagery. • Seamless checkout that includes UPI/Google Pay alongside Shopify’s native methods. • A simple, spam-protected contact form. • On-page SEO best practices (fast load times, structured headings, alt text, meta tags). I’ll supply the product photography, copy, and brand guidelines; you’ll handle theme selection or custom development, configuration, and light graphic tweaks so the pastels ...

    Perfect My Cross Platform App

    Verified

    Take My App To 100% My cross-platform app is already live on both the App Store and Play Store and generally runs well, but a handful of finishing touches are holding it back from perfect. I need someone who can jump into an existing codebase and knock out the last few issues so the product feels rock-solid to every user. I can help you with Claude subscription. Key areas that need attention • iOS voice feature – the functionality is coded but the permission handshake is failing on some devices, so the microphone dialog never appears. • Backend stability – the Node.js API on AWS (EC2 + MongoDB Atlas) goes down intermittently and response times spike under load. I want logs cleaned up, memory leaks traced, and sensible auto-scaling or monitoring put in place. •...

    I need a dedicated Android application that functions as a lightweight CRM. The goal is to let my team manage customer information quickly and reliably from their phones—viewing contacts, adding notes, and updating deal stages without having to open a desktop browser. The scope is limited to Android only; no iOS work is required right now. I will provide brand guidelines and any existing data structures we already use so you can map fields cleanly inside the app. Key deliverables: • Fully functional APK ready for Play Store submission • Clean, well-commented source code • A brief setup guide so I can build future versions internally Please factor in basic UI/UX polish, user authentication, and simple offline handling so field staff can keep working during sp...

    My company needs a fully-featured mobile application that runs natively on both iOS and Android. The core of the app is a secure customer database where I can enter and update contact information, purchase history, preferences, and any new data fields we decide to add later. All records must sync instantly so that staff never see stale data. Alongside the customer module I also want built-in work tracking. Each job should move through task management, real-time progress updates, and time tracking. I need an at-a-glance dashboard that shows who is doing what, how far along each task is, and the hours already logged. To close the loop, the app will include a payment gateway so we can settle invoices without leaving the workflow. I’m open to Stripe, PayPal, or a comparable PCI-complia...

    Readymade Fleet GPS Platform

    Verified

    I need a complete, ready-to-deploy GPS tracking and fleet-management system. The web portal must give me one master account where I can create new client companies, add their vehicles and devices, decide whether each unit is online or offline, and push configuration commands. Every company created under the master account should have its own login hierarchy, and at minimum I have to be able to grant an “Admin with full control” role; if your solution already supports lighter “view-only” levels that’s even better. Core functionality has to include: • Real-time tracking with live map refresh • Geofencing with entry/exit alerts • Full trip history, analytic reports and export options • A consolidated fleet dashboard (fuel, maintenance, ...

    I’m thinking of building an app called “numo”. The idea is super simple: whenever you buy something and your bank sends you an SMS transaction message, the app automatically reads it and records the expense for you. So instead of manually writing down your spending, everything gets tracked automatically. For example, if you buy coffee and get an SMS saying: “45 SAR spent at Starbucks” the app instantly adds it under the “Coffee” category. The goal is to make expense tracking effortless because most people are too lazy to manually enter expenses every day. I also want a really fast way to add or edit expenses. Like on iPhone, you could double tap and a small quick-add popup appears so you can instantly add an amount, edit a transaction, or even ...
