Από 15,346 αξιολογήσεις, οι πελάτες αξιολογούν τους App Store Optimization Experts με 4.9 από 5 αστέριαI have purchased two complete Flutter app source code from Codecanyon, android applications and backend is ready now i will provide you with the full source code and the official documentation for ios apps. All I need is for you to follow those documents step by step and turn both projects into production-ready iOS builds—no custom features or redesigns, just a clean implementation exactly as described by the authors. Right now I have no Apple Developer account, Firebase project, or other API keys in place. Part of the job is therefore to help me create and connect whatever certificates, bundle IDs, or third-party keys the templates call for so the apps pass App Store Connect validation. Deliverables • Two Xcode projects that compile without errors on the latest stable Flut...
We are looking for an experienced Android app publishing specialist to help us prepare and upload our mobile app to the Google Play Store using a compliant Google Play Console process. The freelancer must have strong experience with Google Play Console, Android app release preparation, app signing, policy compliance, testing requirements, store listing setup, privacy policy, data safety form, and release management. Scope of Work: 1. Review our Android APK/AAB before submission 2. Check app compliance with Google Play policies 3. Help prepare Play Store listing: title, description, screenshots, icon, category, contact details 4. Configure app signing and release build 5. Assist with closed testing / internal testing if required 6. Complete Data Safety and privacy-related forms 7. Upload...
I have just finished translating my iPhone app into several additional languages and need a fast, detail-oriented check to be sure everything reads naturally and fits on screen. The job is intentionally small—about 20 minutes of work—covering the App Store description, the marketing screenshots, and a quick look at the in-app strings through TestFlight (link provided after award). Please open the materials I send, spot any typos, awkward phrasing, or text that gets cut off, and return a brief note with the corrections. One clean text file or a set of annotated screenshots will be perfect. That’s it—no heavy rewriting, just a precise sanity check so I can submit the update with confidence.
I need a straightforward chat application that runs on both iOS and Android so my friends and I can message each other in real time. The only conversation mode required right now is text, but it has to feel lively—built-in emojis and a browsable sticker picker are must-haves. No voice or video calling this round. A clean interface, quick message delivery, and solid history sync between devices are the priorities. You may use Firebase, , AWS AppSync, or another real-time backend you trust, as long as it keeps messages snappy and secure. The architecture should be flexible enough that voice or video features could be layered on later even though they are out of scope for this milestone. Deliverables • Fully functional iOS and Android builds with source code • Real-t...
I’m ready to publish my Base44 app and would like an experienced hand to guide the entire submission process for both Apple App Store and Google Play. The codebase is stable; what I need now is a smooth hand-off from build to live listing. Here’s what I still require: • Design and export final-spec app icons and hero screenshots for every required resolution. • Craft a concise, keyword-rich description for each store, including optimized short and long text, plus curated keyword fields for Apple. • Generate compliant privacy-policy and support URLs (simple static pages are fine) and link them correctly inside App Store Connect and the Play Console. • Configure both store listings, upload the builds, fill out all metadata, set age ratings, and submit f...
Tengo mi app Lovable casi lista, pero aún quedan varios detalles técnicos antes de publicarla. Busco a alguien que pueda cerrar este sprint y dejarla preparada para producción: 1. Conectar la API de la base de datos de artículos científicos que ya tengo seleccionada, mostrando los resultados dentro de la interfaz actual. 2. Configurar el plan de pago como prueba gratuita con opción de compra: el usuario disfruta X días sin costo y, al vencer, se activa el cobro recurrente que definamos. 3. Restringir ciertas funciones para estudiantes: solo quienes se registren con carnet y datos académicos podrán acceder a esas secciones. 4. Verificación de correo mediante código numérico enviado al email durante el regis...
I already have a fully working Android build created with OpenCode and AI Agent; the APK is signed, tested, and linked to Firebase. What I need now is an expert release engineer who can turn this work into two live store listings—one on Google Play and a brand-new companion on the Apple App Store. Google Play • Take my existing APK (or convert it to the recommended AAB) • Complete console configuration, data-safety form, screenshots, content rating, and rollout to production Apple App Store I am not yet enrolled in the Apple Developer Program, but I will handle the enrolment fees and paperwork myself. From there, I need you to set up every technical piece I’m missing—certificates, provisioning profiles, Xcode workspace, TestFlight builds, and the final...
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’m ready to take my finished iOS app live and need someone who can handle the entire App Store submission process swiftly and correctly. The build is complete, fully tested, and I already hold an active Apple Developer account. All required assets—icons, screenshots, descriptions, even the privacy text—are prepared and waiting in a folder. Your job is to: • Create the production build in Xcode (or validate the one I provide), sign it with the correct certificates and profiles, and upload it through Transporter or Xcode Organizer. • Configure the listing in App Store Connect: pricing, category, keywords, age rating, and any compliance questions. • Set up TestFlight (if you feel it helps speed review) and move the build into the “Ready for Review...
I need a production-ready Android app that lets Muslim investors search Indian stocks, see an immediate Halal / Haram verdict backed by transparent Shariah-screening logic, and dig into key financial ratios before subscribing for deeper data. Core flow • Users sign in with Firebase Auth, land on a clean Flutter UI, type any NSE/BSE ticker, and get real-time financials pulled from your chosen market data API. • Your code then runs my Halal screening rules, surfaces the pass/fail result, and shows the individual ratios that drove it (debt, income purity, liquidity, etc.). • A tabbed screener (weekly, monthly, quarterly, half-yearly) lets them filter and sort all listed stocks. • Each stock page embeds our educational YouTube playlist to explain the metrics in c...
I’m looking for a developer who can turn a responsive web application into fully-packaged builds for both Google Play and the Apple App Store. The core site is already outlined; what I need is the mobile layer that feels native, passes each store’s submission checks, and is ready to ship within the coming month. If you’re comfortable wrapping web code in a cross-platform framework (Flutter, React Native, Ionic, or similar) and can handle the store certificates, provisioning profiles, and final uploads, this project is a great fit. Clean, maintainable code and smooth performance on mid-range Android devices as well as recent iPhones are essential. Deliverables (by hand-off day): • Android APK/AAB and iOS IPA ready for store submission • Source code with cle...
I have an unfinished project that I am still working on, and I need someone who can help me publish it on Google Play. However, my account already has a limited number of projects uploaded. What I would like is for you to select one of the existing projects on my account and replace it with the new project. Please make sure you understand this request clearly. If anything is unclear, I kindly ask that you reach out and ask me for clarification.
My Android app is already live, but I need a reliable developer who can step in whenever I want to refresh or fine-tune it. The core of the job is feature-level upkeep: whenever I decide the icon needs a facelift, screenshots should tell a clearer story, or the Play Store description requires new wording, I want to hand the task to you and know it will be handled quickly and correctly. Typical requests you can expect: • Replace the current app icon with a new asset and push the update through the Play Console. • Swap in updated screenshots that better showcase new builds or seasonal themes. • Edit or rewrite the store listing text for promotions, keyword tweaks, or policy compliance. • Roll out light feature updates inside the APK when needed—think minor ...
I have two fully-built iOS applications ready to go and I need an experienced developer who can take them the final mile: publishing them under my Apple Developer account. The binaries are complete, so there’s no additional coding or testing required—your focus will be on a smooth, compliant submission. Here’s what I need from you • Log in to my Apple Developer account and App Store Connect (credentials shared securely) • Configure both apps with the standard store settings—nothing custom or complex this time • Prepare every piece of listing content: polished descriptions, compelling keywords, accurate category selection, and high-quality screenshots for all required device sizes • Handle the entire upload workflow in Xcode and App Store...
