I have a fully finished Android game that is ready to ship to Google Play. What I need from you is straightforward: use your publisher account or guide me through mine to get the build live, set up the listing (screenshots, icon, content rating, privacy policy link, etc.), handle initial release approval, and then provide ongoing maintenance—version updates, compliance checks, crash-related fixes, and timely replies to any store alerts. The build itself is final, so no code changes or feature tweaks are expected right now, and I’m not looking for extended ASO work; the focus is on smooth publishing and reliable upkeep once it is in the store. If you already manage several games on Google Play, know your way around Play Console policies, and can commit to quick turnarounds fo...

I'm looking for an experienced mobile app developer to help resolve several critical issues before we can launch our app on the market. Key Issues: - API Server Downtime: The primary issue is server downtime. I need a reliable fix to ensure stability and prevent any future outages. - Store Approval: I also need assistance in getting the app approved by the necessary app stores.

The goal is simple and measurable—drive a meaningful lift in Android installs for my app, which you can preview here: At the moment, visibility on Google Play is modest; I’d like to change that through a tightly-focused growth push that turns impressions into downloads. Scope of work • Analyse current store listing, keywords, creative assets and user reviews to spot quick-win optimisations. • Design and launch a data-driven acquisition campaign centred on Android users—social, influencer, paid placements or a smart blend of these channels if it maximises ROI. • Track installs, cost-per-install and retention day-7/day-30 so we can see exactly what’s working and iterate fast. • Provide weekly performance snapshots and a concise wrap-up re...

My Android app is fully built and every asset is packed and ready. What I now need is a reliable developer who can take it across the finish line by publishing it on Google Play for me and then keeping it healthy with regular maintenance. Here’s the rhythm I’m aiming for: once the app is live, I’d like a maintenance release roughly every month. These updates will focus on the usual upkeep—bug fixes, performance tuning, and any minor tweaks needed to keep users happy on the latest Android versions. I’ll supply source code, artwork, copy, signing keys, and release notes; you handle the build, upload, and rollout through the Play Console, plus any follow-up configuration that Google requires. To make expectations crystal-clear, the initial milestone is the succ...
I have finished builds for both an iOS and an Android app and now need a seasoned release partner to steer them smoothly through App Store Connect and Google Play Console. Accounts are already in place—my Apple Developer account and Google Play Developer account are fully active—so you can dive straight into the submission workflow. I will supply the signed IPA and AAB/APK files, artwork, copy, privacy-policy URL, and any other assets you request. Here’s what I expect from you: • Set up all metadata, screenshots, and compliance items in App Store Connect and Google Play Console. • Upload the builds, configure bundle identifiers, versioning, and in-app purchase settings if required. • Resolve any validation errors or policy warnings, then submit for ...
I need a full-featured VPN application built for Android, iOS, and Windows. The core experience must feel identical on every platform: users pick a server, hit connect, and enjoy a secure, leak-free tunnel. Essential functionality • Server list that can be refreshed remotely, sorted by real-time ping, and filtered before connection • One-tap Server selection plus an Auto-connect option that obeys user rules (on app launch, on unsafe Wi-Fi, etc.) • Always-on Kill switch that survives network changes and guarantees zero traffic outside the tunnel • DNS management inside the app so I can point users to custom resolvers or a local blocker Protocol support OpenVPN (TCP & UDP), WireGuard, L2TP, and an HTTPS Proxy mode must be selectable per server or globally. Swi...
I’m building a tech-driven start-up in the entertainment space and I’m looking for a true partner who can take our product from whiteboard concept to live deployment. Your deepest strength should be Mobile App Development, and I have already chosen Flutter with Dart as the core stack so we can ship simultaneously on Android and iOS while keeping one codebase. You’ll be responsible for both the customer-facing front end and the supporting back end, selecting the right cloud services and setting up a pipeline that lets us scale gracefully once the user base starts to grow. From early architecture decisions through ongoing feature releases, this will be your product to shape. Compensation is entirely equity-based to start: 15–20 % of the company, reflecting the imp...
Thorough functional testing is required for my hourly slot-booking app for futsal, live on both the App Store and Google Play. After installing the current production builds, explore every corner of the app, compile your own exhaustive feature list, and verify each item’s behaviour. What has to reach me at the end: • A feature matrix that you created yourself, showing every discovered feature and a clear Working / Not-Working verdict. • Reproducible bug reports for anything that fails, complete with steps, screenshots or screen recordings, and device/OS details. • A short executive summary highlighting critical issues, usability pain points, and quick-win improvements. Please include a detailed test proposal with your application—outline the devices ...
I’m ready to move my store into a fully featured mobile experience and need an experienced Flutter developer to make it happen. The goal is a single code-base e-commerce app that runs smoothly on both iOS and Android, follows current Flutter best practices, and is production-ready for App Store and Google Play submission. Core scope • Build a modern, responsive UI that reflects my brand’s existing look and feel • Integrate secure checkout, product listing, cart, payment gateway and order-tracking workflows • Connect the app to my current backend (REST API; JSON) and ensure real-time stock updates • Implement push notifications, deep-linking and basic analytics • Package, test and hand over both release builds with clear deployment instructi...
The task is to build a full-featured, cross-platform mobile application for an online store that must feel completely native on both iOS and Android. I need a single code-base solution—Flutter, React Native or a comparable framework is fine—as long as performance and UI polish match platform standards. Core features include a browsable product catalogue, intuitive search & filtering, secure user accounts, a streamlined cart/checkout flow, and integration with a mainstream payment gateway. Clean architecture, scalable state management and clear documentation are essential so future updates remain straightforward. Please focus your proposal on relevant experience delivering cross-platform e-commerce apps: the frameworks you used, any notable performance optimisations, and e...
I run an Android-only app aimed at the general public and, so far, the only growth lever I have pulled is in-app advertising. Installs have plateaued, so I’m ready for a fresh, data-driven push that combines smarter ad placement with organic tactics I have yet to explore. Here is what I need from you: • A concise growth plan that lays out the channels you recommend (Google Ads, Play-Store ASO, social media or anything else you find viable) and the projected cost-per-install range for each. • Full campaign setup and creative assets where required, followed by hands-on optimisation during the first four weeks. • Weekly reports that track impressions, clicks, installs and retention so we can quickly double-down on what’s working. Success will be measured...
I already have a cross-platform codebase in place, but it is still in a rough “skeleton” state. I need an experienced mobile developer to take that foundation, tidy up the architecture, and turn it into a production-ready application for both iOS and Android. The core work involves: • Implementing robust user authentication • Wiring up push notifications (remote and in-app handling) • Enabling in-app purchases that comply with Apple and Google guidelines • Dropping in the design assets I will supply (all screens, icons, and splash art are ready) Once the feature set is stable, I will also need you to configure release builds, prepare store-ready packages, and supply concise build/deployment notes so I can reproduce the process in future updates. Cle...
I already own the full source code of my business app and I keep an active Apple Developer account, yet the build that once ran on my iPhone and iPad now shows “no longer downloadable.” I have the project on my laptop; what I need is an experienced mobile developer to: • rebuild the current code in Xcode (and Android Studio, as the app was originally produced for both platforms), • upload fresh binaries through App Store Connect and Google Play Console so I can install the new version on my personal devices right away, • walk me through updating both the logo and the bundle/package name, supplying the new assets in the correct sizes and formats, and • configure paid distribution so I can charge other businesses that want to use the app under their own...
I want a specialist who can do ASO on English, Polish and Spanish, elevate it, then build fully localised keyword sets and persuasive store copy for the other two languages so the app can rank and convert consistently across all three markets. Your work should be grounded in solid keyword research, competitor benchmarking and an ear for natural-sounding, region-specific phrasing. Please keep metadata length limits, character restrictions and best-practice formatting for both the App Store and Google Play in mind throughout the process. Deliverables • Key word optimisation and short and long optimisation for key words • New, research-driven keyword lists for English and Polish and Spanish • Fresh English and Polish Spanish short & long descriptions, titles and subtit...
I have a live mobile app on both iOS and Android that needs a full refresh. My priorities span three areas at once: • Sharpen the User Interface so the screens feel modern, consistent and intuitive. • Optimise Performance—faster load times, smoother animations, lower memory use. • Add a short list of new features that I will share once you have reviewed the current build. I’ll give you access to the existing repositories and an overview of the current architecture. After an initial code and design audit, I’ll need a clear action plan with milestones, then iterative builds I can test on TestFlight and internal Android tracks. Deliverables 1. Updated source code with in-line comments and a brief change log. 2. New UI assets integrated and pixel...
Goal: Increase app installs by improving Play Store screenshots / Generate high quality ads App Type: Dating App (India-focused) Target Audience: * Male / Female - 18–35 which gives feel of high creatives

I already run a Classima-based listing site and have purchased the official React Native source code that RadiusTheme supplies for the companion mobile apps. Your assignment is straightforward: start at step 1 of the guide below and carry it right through to successful publication on both stores. What I will hand over: • The complete, unmodified app code package • My active developer accounts for both Google Play and Apple App Store What I need from you: • Build, configure and connect the app to the existing WordPress/Classima backend exactly as documented. • Apply a handful of minor tweaks I will specify once we begin (nothing structural—mostly wording and colour adjustments). • Create any missing store-listing assets—icons, feature gr...
I’m looking to keep my Android app visible and competitive on Google Play through continual App Store Optimization and organic SEO. Keyword optimization is the principal focus: I already have a detailed list of category-specific keywords and need a specialist who can weave them naturally into the title, short description, long description and update strategy. Beyond the initial rewrite, I’d like ongoing monitoring and fine-tuning so rankings improve steadily without relying on paid installs or ads. Deliverables I expect: • Refined metadata built around my existing category keywords • A short rationale explaining any wording changes you make • A simple performance report after each update (keyword positions, installs, retention) If you have a proven trac...
Requirement Title Flutter + Supabase Developer Needed for Campus Dating Logic, Aura System, RevenueCat Integration & Play Store-Ready Build Project Overview We are building a private campus network app for colleges, with a gated dating module inside the platform. We need a developer who can work on the matchmaking system, aura points system, RevenueCat subscription integration, Flutter integration support, and final Play Store-ready Android build. This is not a full app from scratch. The core app and some frontend/backend structure already exist. The requirement is focused on implementing and refining specific medium-complexity systems cleanly within the existing setup. Backend is based on Supabase and app frontend is in Flutter. Scope of Work We need help with the following: 1...
The Android app is finished, tested, and already signed; what I need now is a developer who knows the Google Play Console inside out to push it over the finish line. You will receive the final AAB file together with every required graphic asset—icons, screenshots, and the feature image are all ready to go—so you can focus entirely on the submission itself. Alongside the technical upload, I’d like you to polish and update the existing store description. You’ll work from my current copy, tightening it for clarity, keyword relevance, and policy compliance while preserving the app’s voice. Deliverables • Upload the AAB to my Play Console account, completing every mandatory section (content rating, privacy policy link, release track, country availability, ...
I already have the signed AAB/APK, screenshots, feature graphic, and full store listing text prepared, so development work is not required. What I still need is an experienced Play-Console professional who can: • Walk me through creating (or, if policies allow, create on my behalf) a new Google Play Developer account and make sure all settings—tax, content rating, privacy, and policy declarations—are correctly configured. • Upload the build to the console, set up the appropriate tracks, and obtain review approval. • Configure an internal test track for 20 users. I do not yet have the tester Gmail IDs, so I’m looking for guidance on the best way to recruit or generate them and manage their invitations. • Verify installation, basic functionality, ...

Creative Branding & App Store Assets My goal is to make the app look like a "Must-Have Professional Utility." Positioning Note: Although this is an MVP launch, branding should reflect a “Professional Early Access Utility” to balance premium presentation with realistic feature scope. 1. Visual Asset Creation (Screenshots & Icon) The Task: Design 5-6 high-fidelity screenshots for the App Store. Technical Requirement: Screenshots must comply with Apple (6.7”, 6.5”, etc.) and Google Play device size requirements. Deliverables should include export-ready PNG files for submission. Style Guide: Dark mode, professional, sleek, using deep indigos and neon "Profit" greens. Avoid cartoonish poker graphics. Tooling: Use Canva, Figma, or a dedicat...

Saya ingin membangun sebuah aplikasi seluler media sosial yang berfungsi mulus di Android maupun iOS. Fitur inti yang saya butuhkan adalah Pesan pribadi yang aman, cepat, dan mudah dipakai—pengguna harus bisa mengirim teks, foto, serta stiker dengan enkripsi end-to-end. Teknis yang saya bayangkan: • Stack lintas-platform seperti Flutter atau React Native agar satu basis kode dapat dirawat efisien. • Backend real-time (Firebase, Supabase, atau teknologi setara) untuk sinkronisasi pesan instan. • Sistem autentikasi sederhana via e-mail atau nomor ponsel. • Panel admin dasar untuk memantau laporan penyalahgunaan. Walau tahap pertama berfokus pada Pesan pribadi, arsitektur perlu cukup fleksibel supaya fitur lain—misalnya notifikasi push atau berbagi foto...
