From 32,966 reviews, clients rate our PhoneGap Experts 4.8 out of 5 stars.I’m moving quickly toward user testing and need a stripped-down yet polished Flutter MVP. You will receive my complete user journey, logo, colour palette, and fonts; from there your focus is to turn that vision into a cleanly organised widget tree, wire it to a lightweight backend (Firebase is perfectly acceptable), and deliver runnable test builds on both Android and iOS. The heart of this build is authentication and a simple profile. Users must be able to sign up and sign in with either traditional email-and-password or phone number verification, stay logged in across sessions, and log out cleanly. Once inside, a profile screen lets them view and edit their personal information, with all changes persisting immediately to the backend. A password-reset flow should work from both the...
I’m ready to move my wire-framed concept into a working React Native application that runs smoothly on both iOS and Android from a single codebase. The first release needs to cover user onboarding with Facebook social login, the main set of screens outlined in my feature list, and push-notification handling. Code quality is important to me: I want a clear folder structure, sensible state management (Redux, Zustand, or another industry-standard solution you can justify), and descriptive in-line comments so future contributors can ramp up quickly. At the end of every milestone I’ll need signed iOS and Android builds that I can sideload onto real devices for hands-on testing; fastlane or a similar CI step is welcome if it keeps the process repeatable. Deliverables • R...
I want a straightforward mobile app that lets my borrowers stay on top of their loans after the funds have been disbursed. The app’s sole focus is management & repayment; I am not tackling the application or approval stages here. Core goals • Give each customer a clear snapshot of their outstanding balance. • Provide an automatically generated repayment schedule that updates the moment a payment posts. • Send timely payment reminders (push, SMS or email—whichever is easiest to wire up). • Offer an “instant loan” top-up feature so qualified users can draw a pre-approved amount without leaving the app. Technical expectations • iOS and Android builds (Flutter or React Native are both fine; I’m open to native if you have ...
I want to launch a complete betting experience that runs smoothly on iOS, Android, and any modern Web browser. The project includes both the mobile apps and the public-facing website, all driven by a single back-end so updates roll out everywhere at once. Core functionality I need from day one: • Live betting with real-time odds refresh and bet settlement • Secure in-app payments covering the major gateways plus local options we will shortlist together • User profiles with KYC support, balance tracking, and detailed bet history The exact wagering categories—whether sports, casino games, horse racing, or a mix—can be finalised once we review licensing and market priorities, so bring your insights on industry compliance and regional restrictions. I’m...
I’m looking for a developer who can deliver a working AI-powered dance challenge app that runs on both iOS and Android. Speed matters—I’d like to see an initial build as soon as possible. Scope of the first release • Single codebase that compiles cleanly for both mobile platforms (React Native, Flutter, or similar). • Camera module so users can film and submit their dance entry. • Lightweight backend or cloud function to accept uploads and return a simple success message (we can expand scoring logic in later iterations). What I will provide • Branding assets (logo, color palette). • Sample challenge videos to test the recording flow. Deliverables • Source code in a private repo. • Step-by-step setup guide. • A short...
We need an experienced WebAR / computer vision developer to create a browser-based virtual piercing try-on. Users should open a webpage on iPhone/Android, activate the camera, and see a virtual stud realistically positioned on their ear. The key challenge is reliable ear/eartlobe tracking while the head moves. This is NOT a request to copy existing commercial software. We want an independently developed solution using open-source or approved licensed technology. FIRST MILESTONE – PAID PROOF OF CONCEPT Deliver a working browser demo that: * Uses live mobile camera * Detects/tracks the head and ear * Places a virtual 2–4 mm stud on the earlobe * Keeps the stud reasonably anchored during head movement/rotation * Works on iPhone Safari and Android Chrome Possible stack: Media...
I need a production-ready ride-hailing and bike-taxi platform built from the ground up, comprising: • Customer App (iOS & Android) – Core flow for booking and cancelling rides, including bike-taxi options – Secure payment gateway integration (cards, wallets, UPI) – Personal ride history with in-app ratings and feedback • Driver App (iOS & Android) – Self-service onboarding with document upload and real-time verification – Trip management dashboard, live navigation, and status updates – Earnings ledger with daily payouts, summaries, and withdrawal requests • Web-based Admin Panel – Live trip tracking on interactive maps – Driver and customer management tools – Fare, commission...
I need an Android developer to build a modern social networking mobile application. • Android app development using Kotlin or Java • User registration and login with Email, Phone and Google Sign-In • User profiles and profile management • Social media feed with posts • Photo and short video upload • Likes and comments • Push notifications for likes, comments and messages • In-app private messaging/chat • Firebase or another scalable backend • Cloud database and storage • Basic analytics and crash reporting • Clean architecture using MVVM/Clean Architecture and Jetpack • Complete Android Studio source code • Release-ready APK/AAB and basic Google Play publishing assets The app should have a modern, intuitive UI and work...
I have an existing mobile application built using React Native, which is currently live on both Android and iOS. We need to implement specific changes/improvements to the existing application. The work will involve updating the current React Native codebase, implementing the required changes, testing them thoroughly, and ensuring everything works smoothly across both platforms. Will share list of changes in chat .
I need an experienced freelancer to handle the complete sale of my digital asset A2Z Edit (), a fully functional, multi-platform online toolkit with 90+ browser-based tools for image editing, PDF manipulation, OCR (English & Arabic), QR generation, and file management, built on 14 with a perfect 100/100 Lighthouse score, 268 pages of content, and published Android and Huawei apps, which has already generated 10,000+ Google impressions, 1,000+ unique search queries, first-page rankings on both Google and Bing with AI overviews, a Trustpilot 3.7 rating, 210 backlinks from 116 referring domains, and 142 users with 944 page views in just 10 days, all running on Vercel's free tier with zero monthly costs and a domain pre-paid for 2 years, currently pre-revenue but ready for AdSense, p...
I need a complete Android marketplace that lets people buy and sell items with the same flow and feature depth users expect from OLX. The project covers everything from the native app itself to the backend, hosting, and an admin panel that gives me full control over users, listings, and reported content. Core build • Android-only native application (Kotlin or Java in Android Studio) • Real-time GPS so users can browse ads near them, update their location on the move, and receive geo-based suggestions • Secure sign-up / sign-in, user roles, and an admin web panel to approve, suspend, or delete accounts and ads • Product listing screens with category management, advanced search, and multi-layer filters • In-app chat, push notifications, and email/SMS trigg...
I have a mobile app already running inside Replit; the next step is taking it live on both the Apple App Store and Google Play. I need clear, hands-on guidance—preferably screen-shared or well-documented—in setting up the entire release pipeline from Replit to TestFlight and the Play Console. Key features that must remain functional in the published builds are: • User authentication (email + social sign-ins) • Push notifications (FCM/APNs) • In-app purchases (consumable & subscription) What I expect at the end: • A repeatable build script or Replit-native workflow that outputs signed iOS (.ipa) and Android (.aab) packages. • Step-by-step documentation of every store requirement you handle—certificates, provisioning profiles, keystore...
I’m building a full-scale ride-hailing application that runs seamlessly on both iOS and Android. The passenger side must allow easy registration, secure login, real-time vehicle tracking on an interactive map, and smooth in-app payments through an integrated gateway. On the driver side, the app should mirror this polish while adding dedicated tools: quick driver sign-up and authentication, a ratings & reviews system visible to passengers, plus a clear dashboard summarising trip history and earnings. To keep everything in sync, implement reliable push notifications and a lightweight backend that handles matching, routing, and payment logic with minimal latency. Clean, scalable code (Swift/Kotlin or a proven cross-platform stack such as Flutter or React Native) is important s...
