From 247,039 reviews, clients rate our iPhone Developers 4.9 out of 5 stars.I’m building a Unity-based 3D game where players assemble separate pieces into a finished object—the core mechanic is “construction of pieces.” I need end-to-end support: C# gameplay programming, stylised 3D art, and a clean, intuitive UI that guides users through each building step. Here’s what I’m looking for: • Core gameplay loop coded in Unity 2021+ (C#) that snaps, rotates, and validates parts in real time. • Modular 3D assets (pieces, finished models, ambient props) with optimized meshes, UVs, and PBR textures. • A straightforward UI/UX flow: start screen, part picker, hint overlay, progress feedback, and level-complete pop-ups—all wired into the game manager. • A tidy project hierarchy and commented scripts so my...
I’m ready to bring a new idea to life on both iOS and Android and need a developer who can own the full build from first mock-up to store submission. Although the concept itself will be shared after we sign an NDA, the goal is a polished, stable and modern mobile experience that feels native on each platform. Because the app must launch simultaneously in the App Store and Google Play, I’m open to whichever tech stack you feel delivers the best balance of performance and development efficiency—whether that’s React Native, Flutter, Kotlin/Swift side-by-side, or another proven approach you recommend. I am looking for a developer who lives in Afghanistan and has EXPERIENCE: examples of apps you have shipped, the scale of your role on those projects, and any metric...
I have just installed a new Android app and, as a first-time user, I need a clear understanding of every feature it offers and how to operate them confidently. What I’m looking for is a concise, beginner-friendly walkthrough that explains each menu, button, and hidden option in a way that feels intuitive rather than technical. Deliverables • A step-by-step written guide (PDF or Google Doc) that maps out the main screens, what each icon does, and the quickest path to complete common tasks. • Annotated screenshots or short screen-record videos to illustrate actions that are hard to describe in text alone. • A short tip section highlighting shortcuts or lesser-known features that prevent rookie mistakes. Once the guide is ready, I’d appreciate a brief Q&...

WhatsApp shuts down the moment I tap its icon on my iPhone, so I never even reach the chat screen. I have already tried the usual quick fixes—restarting the phone, checking for iOS and WhatsApp updates, and freeing up storage—but the crash persists. The problem come from a backup file. My phone was full of storage and WhatsApp have not properly saved the chat. The file is bigger than the file I need someone who knows their way around iOS-level diagnostics, crash logs, and WhatsApp’s sandbox files to pinpoint the cause and guide me to a working solution. Whether the answer involves a clean reinstall without losing chat history, tweaking device settings, or digging into console reports, I’ll follow your step-by-step instructions and provide any logs you request. ...
I’m ready to get a full-featured taxi app into the stores and need a developer who can deliver native-quality builds for both iOS and Android from the same codebase. The essentials are clear: • Real-time GPS tracking so passengers can follow their ride and drivers can see incoming requests in live-map form. • Two account types—passenger and driver—with separate sign-in, profile, and ride-management screens. I’m flexible on the tech stack: Flutter, React Native, Swift/Kotlin, or any reliable cross-platform toolkit you’re comfortable with, as long as the final apps pass Apple and Google store review. Please outline your suggested architecture, the mapping and notification services you’ll integrate, and a realistic timeline for submitting b...
We are looking for an experienced Mobile App Developer to support our hybrid mobile application (iOS and Android). The technology stack will be confirmed, and full access to the existing codebase will be provided. Project Requirements: • Ongoing bug fixing • Add-on feature development as required • App maintenance for both iOS and Android • Ability to work fully in a remote model • Long-term collaboration (please share only sustainable pricing) Budget Note (Important): • We have a limited budget, and we will only consider quotations that are lower and realistic. • Please do not submit inflated or false prices, as we want to avoid unnecessary time wasting. • No negotiation will be entertained — only genuinely lower and sustainable offers will ...
I’m refreshing the public face of my activity-tracker app, Tuntask (live on Google Play), and I need everything ready within a week. The look and feel has to be playful and colorful—mirroring the upbeat vibe inside the app. Here’s the scope: • A responsive, fast one-page landing site that instantly shows why tracking tasks with Tuntask is fun. I’ll host it myself, so a clean export or a share-link from Figma/Adobe XD/Framer works. • Full Google Play ASO graphics: feature image, banners and annotated screenshots that meet current store specs. • A 15–30-second video ad (portrait and landscape) that can double as the store preview and serve for paid campaigns. • Matching social media creatives—square feed posts and vertical stori...
I have an existing Xcode-based voice-chat app that needs a final round of feature completion before it can clear App Store review. The core work falls into three areas: • Audio quality. Integrate reliable noise reduction, echo cancellation, and true HD audio so conversations stay clear even in poor network or loud environments. • User interaction. Build smooth in-app private messaging and scalable multi-user group chat on top of the current architecture, keeping UI consistent with the rest of the app. • Back-end dashboard. Add a lightweight admin panel that lets me monitor rooms, block abusive users, and pull basic usage stats. Once those pieces are in place, I’ll need you to handle the full release workflow: prepare provisioning, pass TestFlight, resolve any App...
The task is to create a polished, cross-platform mobile application focused exclusively on budget planning. Users must be able to: • enter monthly income in rupiah, • set spending limits for custom categories, • track real-time progress against those limits through clear visual dashboards, • view automatic summaries that highlight remaining funds at a glance. I will share a rough feature map and basic wireframes; you transform them into an intuitive UI, build the front-end (Flutter or React Native is fine), and connect a lightweight cloud back-end so data stays in sync across devices. Core flows need to feel snappy on typical mid-range Android phones and recent iPhones. Acceptance is met when I can install TestFlight and Google Internal Test builds that: 1. h...
The screens and user journeys for my player-prop application are already laid out in Flutterflow; what I am missing is the technical glue that turns those designs into a working product. The back end is a Firebase project that’s set up but not yet linked to the Flutterflow front end. I need you to wire the two together, then embed an AI model able to predict over/under outcomes for individual player props and output concise reports a user can review before placing a bet. What I have • All UI/UX completed in Flutterflow • Firebase project with collections prepared What I need from you 1. Connect every relevant screen, widget and action in Flutterflow to the existing Firebase database so data reads/writes, auth and real-time updates work seamlessly. 2. Expose the...
I have a clean CSV file that already holds all the product data—titles, SKUs, prices, images, descriptions, stock levels—for a growing line of jewelry. What I need now is a polished mobile application that reads that file and turns it into an attractive, easy-to-browse catalog on both iOS and Android. Here’s the flow I picture: • On first launch (and whenever I upload an updated CSV to a simple admin endpoint or cloud bucket) the app parses the file and stores the content locally for fast, offline-friendly browsing. • Users open the app to a grid or masonry gallery of product photos, tap to drill into a detail view with zoomable images, full description, price, and an “inquire” or “add to wish-list” button. • Basic filters&mdas...
I need a full-featured social media application built natively for Android. The core experience should allow users to register, create profiles, post text, images, and short videos, follow others, and interact through likes, comments, and direct messages. A clean, modern UI that feels instantly familiar to typical social platforms is essential, and smooth performance on mid-range devices is a must. Behind the scenes, I plan to run a scalable back-end (Firebase or a comparable cloud stack works for me) that handles authentication, real-time feeds, push notifications, and media storage. Please structure the project so new features—such as stories or in-app events—can be added without major rewrites. Deliverables I expect: • UX/UI mock-ups for all main screens • Nati...
I am launching GUNDEX, a new mobile app designed for fans of the Gundam Card Game. GUNDEX helps users: • Track and manage their Gundam card collection • Catalog cards digitally with clean UI • View card details and artwork • Stay organized with favorites, wishlists, and more I am looking for a creator who can produce short-form, engaging, UGC-style content that promotes the app, builds interest in the Gundam TCG community, and generates early user excitement. What I Need I need original, platform-optimized content for: • TikTok • Instagram Reels • Threads • Facebook • X (Twitter) • Optional: YouTube Shorts Your content will help introduce the app, demonstrate features, and attract collectors who would benefit from using it....

I’m ready to transform my social networking idea into a fully-functional Android application and need a skilled mobile developer to guide the entire build. The project is Android-only, so you’ll be working natively in Android Studio, using Java or Kotlin and the latest Android SDKs to create a smooth, modern experience that feels at home on any recent device. The core concept is a community-driven platform where users connect, share content, and interact in real time. I have wireframes and feature notes that we can refine together, but the essentials include secure sign-up/login, user profiles, a dynamic feed, and messaging or commenting capabilities. Clean Material Design, responsive layouts, and thoughtful push-notification handling are important to me, along with privacy be...
I need a straightforward Android MVP that streamlines day-to-day PG / hostel operations. The single most crucial feature is a one-tap approval workflow so the owner can instantly accept or reject any tenant request. Around that, build: • QR-based forms for onboarding, offboarding and rent/payment submissions • A lightweight owner dashboard showing dues, cleared payments and tenant details in real time • Optional WhatsApp or SMS notifications, wired so they can be switched on later with minimal code changes The goal is proof of concept and speed of execution rather than extensive UI polish. Think of RentOk or SpaceBasic as reference points—but do not clone their flows. Preferred stack is native Android in Kotlin or Java, with Firebase (or any rapid back-end you t...
I need a cross-platform mobile app that puts businesses on an interactive map and lets users rate them in the moment. Two core map features are non-negotiable: users must be able to search for a business (İşletme arama) and see or leave user reviews (Kullanıcı yorumları). The twist is the camera flow. After a purchase, the user points the phone at their receipt; the app scans it, recognises the store, and immediately opens the rating screen. An accurate, fast OCR layer (Google ML Kit, Tesseract or a solution you prefer) is therefore essential. I’m open to Google Maps, Mapbox or another reliable map SDK. The build can be native, Flutter or React Native as long as both iOS and Android are covered. Clean, well-commented source code and a short read-me for setup are part of the hand-...
I need two brand-new developer accounts set up from scratch—one with Apple and one with Google Play—and both must be fully activated and ready to publish apps. I will give you: • the exact email addresses that must be used for each enrollment • all verification details Apple and Google ask for (legal name, address, ID scans, phone, etc.) Your job is to handle the entire enrollment workflow, including identity checks, phone or two-factor verifications, and payment of the one-time or annual program fees using your card . When both accounts show “Active” status and allow new app submissions, send me the login credentials along with any recovery codes or additional security information generated during setup. I expect clear step-by-step updates so I ca...

Your Tasks Expand the main level into a long, fun challenge Add new obstacles, traps, and gameplay elements Improve player control & polish the movement Create a simple boss/end section Fix bugs and optimize the environment Light UI improvements if needed Important Notes No multiplayer, no garage, no shop, no advanced systems yet This is a small job to upgrade and polish the existing level If your work is good, there will be fu...

I’m looking for a developer who can take an Android-first approach to building a full-featured social media application from scratch. The core goal is to create an engaging space where users can sign up, build profiles, share posts, and interact in real time—all optimised for the latest Android guidelines. I already know I want a pure Android build rather than cross-platform or iOS right now, so your experience with Kotlin or modern Java, Jetpack components, Material 3 design, and Google Play publishing will be essential. Clean architecture, responsive UI, and smooth performance on mid-range devices matter a lot to me. At this stage the concept includes: • Secure authentication (email or phone number, plus social sign-in if practical) • A feed where users can publ...
I want to replicate the key experience of the “Bounce: luggage storage nearby” application, but as a native iOS build. Please watch the walkthrough I made reference to for a clear feel of the flow and design: Scope • Platform: iOS only. • Core features: a live store-locator map that surfaces nearby partner venues to store items, a smooth booking & reservation flow, and in-app payment processing. • Accounts: every user must be able to register, sign in, and manage bookings from a personal dashboard. Deliverables 1. Xcode project (Swift or SwiftUI) ready for TestFlight. 2. Fully functional store-locator tied to real-time or mocked geo data, a store that is register with the app to offer storage for clients . 3. Booking pipeline that reserves a ...

I’m ready to turn “Astrogyani” into a seamless cross-platform experience that lets users connect with professional astrologers from any device. The core of the project is an iOS and Android app backed by a responsive website,,admin all centred around on-demand astrological consultations. Key flow • A visitor browses astrologer profiles on the site or in the app, checks past client ratings, then books a time slot that instantly syncs to the astrologer’s calendar. • When the session starts, the user can join an in-app audio or video call, with automatic session timing and secure payment capture. • Afterward, both parties may leave a review that is displayed in real time across the ecosystem.

I need a complete grocery home-delivery app built for both iOS and Android, ready to submit to the App Store and Google Play within one month. The app’s core flow is simple: customers browse my grocery catalog, add items to their cart, pay in-app, and track their order all the way to the doorstep. Key features I expect • Clean, intuitive shopper UI with search, category browsing, and product detail screens • Secure checkout supporting card payments (and the usual wallet options offered by Stripe, PayPal, etc.) • Real-time order status updates and map-based driver tracking • Push notifications for confirmations and delivery updates • Basic loyalty promo code support • Driver and admin dashboards (web or in-app) for order management, status ch...
I have a feature-complete chess game in Unity and now need an experienced developer to wire it up to the external services that make it production-ready. Your sole focus will be API integration—no work on art, board logic, or UI layout is required. Here is what needs to come together: • Payment gateways – set up in-app purchases so players can buy cosmetic items and subscription tiers directly inside the game. • Social media login – enable one-tap sign-in with the major platforms listed in my docs, and make sure new accounts flow seamlessly into our existing user database. • Leaderboard and ranking – plug in the service we use for global and friends-only leaderboards, display ratings inside the lobby scene, and keep them in sync after every ma...

I’m planning an Android application whose core purpose is to generate steady revenue, but the concept is still taking shape. I already know that mobile app development is the right path; however, I need an experienced developer who can guide the idea-refinement phase, propose profitable feature sets, and then build a polished Android app from the ground up. Here’s what I have so far: • A broad goal: the app should deliver clear value that attracts and retains users long enough to support in-app purchases or ad-based monetisation. • Early research on similar apps and potential gaps in the Indonesian market. • A rough outline of possible features—nothing is locked in, so your strategic input is welcome. What I need next: 1. A short discovery sprint to v...
Everything but the code is finished - I have pixel-perfect Figma screens, polished copy, trained AI models, and fully documented REST endpoints waiting. What I need now is a fast, confident mobile developer who can turn all of that into a production-ready app for both iOS and Android within a strict three-day window.

Hi there, I’m looking for someone who can simply review the app for me and check if everything is working 100%. Once you’ve done that, just send me the iOS version through TestFlight and the Android version as an APK—whatever method works to get it running on a Samsung device or emulator is fine. Just let me know the issues you find, and I’ll handle the rest.
I’m ready to launch a full-scale ecommerce marketplace for physical goods and need it running seamlessly on both iOS and Android from day one. The core idea is simple: give multiple sellers an easy way to list, manage, and ship products while shoppers enjoy a slick, familiar buying experience—search, cart, secure checkout, order tracking, ratings, and push notifications included. You’re free to choose the most effective stack (native Swift/Kotlin, Flutter, React Native, or another approach) as long as performance and App Store / Google Play compliance stay front-of-mind. A clean admin portal for product moderation, user management, and basic analytics will also be required so the team can run daily operations without touching code. To keep the project on track, I ne...
I need a developer who already knows FluxStore inside-out to turn my existing multi-vendor concept into a complete app for both iOS and Android. Because the FluxStore framework itself ships with most of the heavy lifting, I’m expecting you to focus on clean configuration, theme tweaks, plugin integration and whatever custom coding is required to make vendor onboarding, product management and order flow run smoothly. If you have shipped FluxStore projects before, your experience should shine through in the way you structure the project, set up build pipelines and handle App Store / Google Play compliance. Please highlight the FluxStore jobs you have completed, the challenges you solved and any performance or UI optimisations you introduced—generic mobile portfolios won’t ...
For the next 45 days my real-time multiplayer card-game site will be running live and I need a reliable developer who can jump in quickly, squash bugs, and polish the experience without disrupting active players. Bugs currently reported range from gameplay logic hiccups to interface glitches and the occasional performance dip under load. Alongside the fixes, I’d like several small but high-impact changes rolled out: a couple of lightweight new features, some UI/UX refinements, and periodic content tweaks that keep the lobby fresh. Nothing massive. iPad users account for a healthy slice of my audience, so part of the brief is to tighten up responsive layouts and squeeze extra performance on iOS Safari—especially during swipe and drag card actions. No touchscreen gesture over...
I have an idea for an iOS-only mobile application and I need a capable developer to turn it into a polished, ready-to-publish product. My background is not in coding, so I am looking for someone who can guide me through each step—from refining the features, setting up Xcode and Swift frameworks, all the way to compiling the final build for App Store submission. The core goals are straightforward: • Build the app natively for iOS (Swift or SwiftUI preferred). • Deliver clean, well-commented source code that I can study and learn from later. • Provide a short hand-off walkthrough (screen-share or recorded video) showing how to run, test, and submit the app. If you have a portfolio of previous iOS projects, that will help me gauge fit. I am flexible on UI style as l...

I want a lightweight, single-purpose iOS application that lets me capture, edit, and browse a customer database on my iPhone. The flow is straightforward: I open the app, tap “Add Customer,” fill in a few text fields (name, phone, email, notes), and save. I also need a basic search so I can quickly pull up an existing record and make changes. I’m happy with native Swift and either Core Data or SQLite under the hood—whatever you feel is faster for a clean, maintainable codebase. No complex sign-up, payments, or social features are required; the app lives entirely on device for now. A simple backup/export option (CSV or JSON) would be a bonus if it doesn’t add much overhead. Deliverables • Xcode project in Swift, ready to compile on the latest iOS versi...

Passengers choose a pickup/drop-off, request a ride, and watch the driver’s approach in real time on an in-app map or on the website. Payment processing is not part of this MVP, but the architecture must keep the door open for adding gateways later. Mobile build Feel free to propose native stacks (Swift/Kotlin) or a single code-base framework such as Flutter or React Native, as long as it delivers smooth geolocation, push notifications, and background tracking. I value a clean...
I’m building a new food-delivery product and need a complete UI conceived for both iOS and Android at the same time. The priority is a friction-free user experience: screens must feel instantly familiar, navigation has to be one-hand friendly, and every tap should move the customer closer to checkout without confusion. You’ll start from my rough sketches and notes, then shape them into polished, high-fidelity designs. Think onboarding, restaurant browsing, menu details, cart, payment, live order tracking, ratings, and account settings—everything a modern delivery app demands.
