From 352,900 reviews, clients rate our Android Developers 4.9 out of 5 stars.I want to take my restaurant fully digital with two tightly-connected products: 1) A customer-facing mobile application that runs on both iOS and Android. Diners should be able to browse the menu, customise items, pay in-app and follow their order status through push notifications. The experience needs to be lightning-fast and visually in line with our brand so repeat use feels natural. 2) A browser-based admin panel for my team. From a single dashboard we must be able to: • monitor and manage incoming orders in real time • add, edit or retire menu items—including photos, prices and availability • review customer analytics such as top-selling dishes, peak hours and repeat-purchase behaviour Stable APIs must link the two systems so every change in the panel is ...
1. Executive Summary & Project Vision We are looking for an expert Full-Stack Mobile Developer (or a specialized agency) to build a revolutionary Home Rental Application that fundamentally changes how users discover properties. The Concept: Traditional real estate apps rely on static grids and list views that cause decision fatigue. Our vision is to adapt the "Instagram Reels" or "TikTok" vertical scrolling model for property hunting. We want to create an immersive, full-screen browsing experience where users can "swipe" through high-quality property videos and images, making discovery rapid, engaging, and intuitive. 2. Detailed Scope of Work Your role will be to translate our Design Phase Guide into a production-ready mobile application (iOS & Andro...
I’m creating GreenThumb, a mobile app that helps city dwellers grow healthier plants with less guess-work. The first release must spotlight comprehensive planting guides—vegetables, herbs, and flowers—delivered in a clean, step-by-step format that adapts to the user’s zone, balcony size, and sunlight profile. Think quick-scan seed-to-harvest timelines, soil and container tips, plus in-app reminders that slot automatically into a personal planting calendar. Beyond the guides, I want basic tracking (photos, notes, growth metrics) and a light social layer where people can form or join gardening groups in their neighbourhoods. Group feeds should make it effortless to post progress shots, swap advice, and arrange informal seed swaps or rooftop meet-ups. Scope • ...
I need an AppSheet application that lets our shop-floor team capture both photos and videos for every production run, pick the relevant order number from a dropdown list, and have those files land automatically in the right Google Drive folder. Once saved, the app should create or update a view-only Drive link so the customer can monitor progress without touching anything on our side. Core flow 1. Backend staff enter the order number, Customer name, etc. 2. Operator opens the app, chooses an order number from the dropdown. 2. They take the required photos and videos along with a geo stamp and a time stamp, order details, QC name. 3. The app pushes each file into a Google Drive structure such as Production Orders/ {Order #}/ Photos or Videos, naming files with a timestamp. 4. A vie...
I’m ready to take my online women’s fitness business to the next level with a fully branded mobile app that blends the best elements of Lenus, Everfit, Stridist and Trainerize, then adds a period-tracking experience similar to Flo and a lightweight AI assistant. Core focus • Coaching and training sit at the heart of this build. I need a smooth way to create and deliver customised workout plans for every client, update them on the fly and see adherence at a glance. • Period tracking must be native, not a bolted-on webview, so clients can log cycles, symptoms and energy levels and see how each phase aligns with their workouts. • An AI layer should answer common questions, surface form-check tips and suggest small plan tweaks based on user data—all whil...
I need a Google AppSheet app that lets my office and canteen staff manage attendance and meal charges simply by scanning the standard UPC codes printed on employee badges. Here’s the day-to-day flow I’m aiming for: a staff member points an Android phone at a badge, AppSheet grabs the UPC, time-stamps the entry, and if the employee buys food, records the items and prices in the same session. At closing time the app should email or save a PDF/Sheet summary showing who came in, how long they stayed, and what they spent. Core functions to build into the AppSheet tables and views • Record entry and exit times on every scan (one tap to flip between IN and OUT). • Track meal purchases against the same badge and date. • Auto-generate daily, weekly, and monthl...

I already have a finished Android application and the signed build is ready to ship. I need a reliable developer who can first walk it through a clean launch on Google Play—handling the Play Console setup, store listing, key management, policy checks, and final publication—then stay on as the point-person for routine maintenance. There are no new features or redesigns on the roadmap right now; the focus is strictly on stability. After release, I’ll rely on you to monitor crash reports, keep the SDK versions current when Google’s requirements change, and step in quickly if any compliance or compatibility issues crop up. Acceptance criteria • The app is live and searchable in Google Play with all assets, descriptions, and tags correctly configured. &bul...

My Android app screens live in Figma and cover the full user journey, yet they still feel like wireframes rather than something a developer can ship. I need a seasoned mobile designer to finesse both the UI and the UX, and you have full permission to adjust layouts as well as refine what is already there. Brand colours, typography and iconography are defined in a short style-guide; everything else can benefit from your creative eye as long as it stays on brand. Key goals • Elevate visual polish so every component follows Material-You best practices and scales gracefully across common Android breakpoints. • Tighten UX flows—micro-interactions, error states, empty states—to ensure each screen feels intuitive and consistent. • Optimise the Figma file itsel...

I need a simple but fully-functioning booking app for home and office cleaning, built in Bubble, FlutterFlow, or any similar no-/low-code tool that lets us move fast with AI-assisted workflows. The cap for this first build is $100, so the scope must stay lean and focused on the core journey: • New users sign up with OTP verification • They pick a date, time, and address; GPS auto-fills their location and shows distance to the nearest cleaner • In-app chat opens instantly and includes a secure payment request the moment the job is confirmed • When the work is done, the client rates and reviews the cleaner On the back end I need a lightweight admin panel where I can approve cleaners, track every booking, release or refund payments, and moderate reviews. Acceptanc...
I already have a Flutter user app paired with a PHP-Laravel back-end for an online food-delivery service. Two things still block launch: 1. Location on launch The app must grab the customer’s current GPS location every single time the app opens—no taps, no confusion. The latitude/longitude should flow to the Laravel API exactly as it does when the user manually selects their address today. 2. Checkout polish I need a careful pass over the existing Flutter checkout screen. Visual glitches, validation quirks or crashes that appear on either iOS or Android should be traced and fixed so payment and order submission run smoothly. When both items are solid, I want a clean build shipped live to the Apple App Store and Google Play. You’ll handle the store assets, provis...

Projekt leírása (Project Description): ​Overview: I am looking for a skilled developer to fix an existing mobile application that has stopped updating due to a 403 Forbidden error. This is likely related to an expired or incorrect API key/authentication that needs to be replaced or reconfigured. ​Beyond the fix, the final goal is to have the app fully functional (updating continuously) and successfully published/updated on the Google Play Store. ​Key Responsibilities: ​Troubleshooting: Identify the root cause of the 403 error and restore the connection between the app and the data source. ​API Management: Update API keys and ensure secure communication. ​App Update: Ensure the app fetches and displays live data correctly and continuously. ​Google Play Console: Handle the rele...
I want a complete, production-ready mobile application that runs smoothly on both iOS and Android. The core idea is a multi-resort booking platform wrapped inside a binary MLM structure: every user can reserve rooms across several partner resorts while simultaneously building a two-leg network that earns commissions from each down-line booking. Key elements to build • Resort booking engine – real-time room availability, multi-resort catalog, date/guest selectors, pricing rules and in-app payments. • Multiple bookings per user – one account may hold overlapping or future reservations, each editable or cancellable under policy constraints. • Binary MLM logic – automatic left/right placement, level-based commission calculations, secure wallet, payout re...
I run a small matrimonial service with roughly 1,000 active profiles and I’m ready to move the entire experience to a dedicated Android app. The overall aesthetic must stay simple and clean—no flashy graphics, just an intuitive layout that keeps the focus on the profiles. Core flow • New users register through phone-number verification only (OTP). I do not want email, social or any other sign-up method. • After login, users can browse or search the profile database. Search should let them refine results by Education, Age, Income, Region and Caste. These filters need to be fast and can be combined in any order. • Each profile will show photo gallery, personal details and a “request contact” button that triggers an in-app notification or SMS aler...

I’m launching a location-based augmented-reality game and need a developer who can deliver functional builds for both iOS and Android within the next month. Players will move through the real world to discover digital items and challenges, so precise geolocation and smooth AR rendering are critical. My ideal workflow is Unity (or another cross-platform engine you’re comfortable with) paired with ARKit, ARCore, and a mapping solution such as Mapbox or Google Maps SDK. I’ll supply the game concept, core mechanics, and all 3D assets; you handle coding, integrating the location services, and packaging the apps for TestFlight and Google Play internal testing. Deliverables • Full Unity (or equivalent) project with clean, well-documented code • Compiled beta builds...

I need a fully explorable 3-dimensional map of Hyderabad’s Hitech City, covering roughly a 5 km stretch of its main streets and recognisable landmarks. The style must stay true to life—textures, lighting, and building proportions should feel as if the player has been dropped right onto the actual road. A single protagonist will spawn on the map in third-person view. Movement and camera control have to run through virtual, on-screen touch controls, much like the layout you find in PUBG Mobile: a left-side joystick for motion, right-side swipe for camera, plus basic run and jump buttons. Smooth 60 fps performance on mid-range Android devices is important. Deliverables • Optimised 3D environment of Hitech City (5 km) with collision, LODs, and baked lighting. • Rigged a...

I need an Android application that gives small teams a simple, reliable way to hold video meetings—similar in feel to Google Meet but trimmed to the essentials. The app must support up to ten participants in a room with smooth audio-video, built-in screen sharing, and an in-call text chat. Recording is outside the scope for this first release. WebRTC is the obvious backbone, and I’m happy with Firebase (or a comparable signaling service) alongside the standard Android SDK in either Kotlin or Java. If you have a different, battle-tested stack that hits the same quality targets, propose it and explain why. Deliverables • Release-ready APK plus Play Store–compliant build bundle • Fully commented source code in a public or private repo • README covering...
I want an app that scans the phone’s camera roll, recognises the same person across different shots, and then lets me decide exactly which images to forward. The core flow is simple: • First, the app analyses every photo, clusters faces that it believes belong to the same individual and shows me those groupings. • From there, I can pick pictures one-by-one or bulk-select them in three distinct ways: individually, by date range, or by geolocation. This mirrors the way I already think about my library, so the interface needs to surface those three filters prominently and let me combine them if I wish. • Once I have a final selection, the app should open the standard share sheet so I can send the chosen files through any installed channel (Messages, WhatsApp, AirDrop...
I need to move funds directly from my local bank account to a recipient’s bank in Cambodia. The goal is a one-off, hassle-free transfer—no payment gateways or third-party wallets—strictly bank-to-bank. Here is where I need your help: • Collecting and formatting the recipient’s Cambodian bank details so they meet SWIFT/IBAN requirements. • Walking me through compliance checks and any paperwork my sending bank might request (KYC, purpose of remittance, etc.). • Preparing the transfer order inside my online banking portal and confirming the routing codes, fee structure, and expected delivery time. • Verifying that the funds land in the Cambodian account and providing a simple receipt or confirmation screenshot once it clears. Acceptance wi...

I would like a secure, reliable way to view a single Android phone remotely so I can monitor its call logs, text messages, app usage/activity and GPS location in real time. Here’s what I need accomplished: • Recommend and configure the most appropriate remote-monitoring solution (MDM platform, custom script over ADB, or any proven third-party tool that supports live dashboards). • Set the target device up so all four data streams—calls, messages, app activity and location—sync continuously without noticeable lag. • Walk me through granting the required permissions on the phone and any server or web console setup on my side. • Provide a short guide for reconnecting or troubleshooting should the device reboot or lose signal. Acceptance criter...
I need our current project, built in Unity 4, migrated cleanly to Unity 6 while keeping the game exactly as players know it. The core work is twofold: first, bring every gameplay mechanic over so it runs flawlessly on the newer engine flow on the latest UI toolkit. No new features are required; this is a straight upgrade focused on compatibility, stability, and a polished feel in the updated environment. I expect you to handle any API changes, package replacements, shader or lighting tweaks, and input-system updates that Unity 6 now enforces. Final delivery is the upgraded Unity 6 project folder ready to open, build, and release version. In this time run in android, need to work with Windows and WebGL too.
I want to launch a mobile experience that blends live-stream shopping with seamless, in-app purchasing—think TTS. The build must ship for both iOS and Android from day one, with user accounts that can authenticate either through email/password or the major social platforms. Core functions I need working flawlessly: • Real-time live streaming where hosts can pin products on screen • A browsable product catalog that stays synced with my backend • One-tap, secure checkout inside the stream and in the catalog view Because I do not have a fixed preference on framework, you’re free to recommend React Native, Flutter, or any stack that delivers smooth video, stable commerce flows, and maintainable code. When you reply, please include: • Direct links or s...

The project is a full-scale, cross-platform cricket fantasy gaming application that must run smoothly on both iOS and Android devices. I already have the feature set clearly mapped out, so the focus is on clean execution and rapid delivery within the next month. Core functionality to implement: • Live score updates pulled from a reliable cricket data API in real time • Robust fantasy team management where users draft, trade and track player performance • Dynamic leaderboards and rankings that recalculate instantly after every scoring event A modern, intuitive UI/UX is essential so users can glide from team selection to live match tracking without friction.

I want a simple, reliable way for families to see exactly where their school bus is and how long it will take to reach their stop. The core flow is straightforward: • Students or parents open the app on iOS or Android, choose their school, bus number and stop from three drop-downs, and immediately see the bus’s live position on a Google Maps view along with an ETA to their selected stop. • The driver runs a companion screen on the same app; when they tap “Start Trip” the phone begins broadcasting its GPS location. Once the route is finished, they tap “End Trip” and tracking stops. • Only two roles are needed for the first release—Students/Parents (view-only) and Drivers (share location). A future administrator role could be added late...
I already have the complete Android source code and APK; now I need an identical iOS build targeted for iPhone only. Every screen, flow and feature must behave exactly as on Android—no additions, removals or alterations. Your job covers: • Setting up the new Xcode project and coding the app in Swift or Objective-C (your call, as long as performance and Apple guidelines are met). • Re-implementing any REST calls, local storage, push notifications and third-party SDKs present in the Android version. • Thorough testing on real iPhone hardware to make sure the build is stable and visually consistent. • Guiding me through App Store Connect, TestFlight distribution, metadata, screenshots and final submission until Apple approves the app. To move forward, please send m...

I want to turn ordinary paper into a fully connected writing surface by building a smart pen that streams everything I write or sketch straight to a companion app. The pen must: • capture handwriting and immediately convert it to editable text, • digitize free-hand drawings with stroke-level accuracy, and • recognise simple air gestures for quick commands such as undo or page-switch. All data should travel over Bluetooth Low Energy so the pen feels cable-free and responsive. On the mobile side I need a single code-base or two native apps that run smoothly on both iOS and Android, displaying the incoming strokes in real time while offering export to PDF, SVG or plain text. Core deliverables 1. Hardware prototype with firmware handling sensing, on-board buffering a...
I already run a real-money, multiplayer Ludo game in production on a React (TSX) front-end with a Node.js backend. Now I want the very same experience packaged as an Android app. You will start from the existing codebase and reuse as much business logic as possible, then reshape it for a smooth mobile flow. The Android build must preserve every live feature—gameplay, wallet handling, real-time matchmaking, authentication, in-game chat, and anything else users already enjoy on the web—while also feeling truly native (push notifications, back-button behaviour, Play-Store-ready signing, etc.). I am happy to consider React Native, Kotlin, Flutter or another approach if it lets us: • call my current REST/WebSocket endpoints with minimal refactor • keep animations and ...
I want to launch a single mobile app that lets drivers handle every routine task around their vehicle without ever leaving their phone. The build has to be truly cross-platform—one code-base deployed to both iOS and Android—so users on either store get the exact same experience. Core modules I need right now are: • Check car details pulled live from the Vahan API • Pay traffic challans seamlessly inside the app • Recharge FASTag in just a few taps • Full buy-and-sell marketplace for used cars For the Vahan integration you’ll work with the official APIs to fetch RC details securely. Challan and FASTag flows will require payment-gateway integration (UPI & cards) and receipts stored in the user’s history. The marketplace should let any...

Android App UI Replica (Jetpack Compose) General Information I have an existing Android application only as an APK file. There is no Android Studio source code — only a decoded version via apktool (res, drawable, xml, png, smali). The app is written using Jetpack Compose, so this task is NOT reverse engineering.
