From 23,399 reviews, clients rate our App Store Optimization Experts 4.9 out of 5 stars.I’m building a fresh, mobile-first puzzle/strategy title and need a game developer who can take it from concept brief through to App Store and Google Play release. The core idea and key mechanics are already sketched out; what’s missing is your engineering and design expertise to turn those notes into a polished, engaging experience that can scale to multiple levels. Here’s what the collaboration will cover: • Selecting the best engine (Unity, Godot, or similar) and setting up the project structure. • Implementing touch-friendly controls, intuitive UI/UX, level-loading, and save systems. • Creating a small but modular level set so I can add new puzzles later without heavy re-coding. • Integrating basic analytics, ads, and in-app purchase hooks...
I’m ready to release my mobile application on both Google Play and the Apple App Store, but I don’t have an active Play Console (or an Apple Developer account). I need someone who can take the builds I provide—APK/AAB for Android and IPA for iOS—or help me package them correctly, then handle every step of the submission process until the app is live in both stores. You’ll make sure the bundle IDs, version codes, screenshots, privacy details, and compliance items meet each store’s requirements, fill out the listing information, upload the builds, respond to any review feedback, and send me the public links once the releases are approved. Deliverables • The same production version of the app available in Google Play and the App Store, ready for user...

I have three mobile apps that already run flawlessly on both iOS and Android; each has been fully developed, tested, and wrapped with the correct build numbers. What I need now is a smooth, policy-compliant release to the Apple App Store and Google Play. Here’s what I will hand over: signed IPA/APK (or AAB) builds, store-ready screenshots, privacy policy links, and all written copy. Your job is to: • Create or configure the App Store Connect and Google Play Console listings • Upload the binaries, fill out metadata, age ratings, app privacy details, and screenshots • Handle the submission process, including any required app-signing keys or certificates • Respond to the first round of store review feedback, if any, until each app is approved and live Accept...

Create App Preview Screenshots for Apple & Google Play based on my existing Figma designs References: Need: -- App Preview Screenshots – for iPhone as high-quality PNG/JPEG -- One Feature Graphic for Google Play – adhering to Google’s 1024×500 spec with safe-zone text placement. Please keep naming conventions clear (e.g., ) so I can drag-and-drop during submission. I’ll share the Figma link immediately
I have already written the Flutter code that talks to my ESP-32-based control board; what I now need is a seasoned publisher who can take my existing project, polish the final build, and release it to both the Apple App Store and Google Play. I’ll remain hands-on with core features and UI, but I want your expertise for the last mile—setting up certificates, provisioning profiles, store listings, and any performance-oriented tweaks that keep the app running smoothly. You will give me limited access so I can jump in for quick text edits or minor layout tweaks whenever I like, while you stay available for deeper performance improvements or future updates as the firmware evolves. Deliverables • Production-ready iOS (IPA) and Android (AAB) builds uploaded and approved i...
Long-Term Technical Partner Needed — React/Supabase/Capacitor Hybrid Native App Absolutely — Long-Term Technical Partner Needed — React/Supabase/Capacitor Hybrid Native App Project Type: Ongoing / Long-term Platform: Web app already built, needs Capacitor mobile completion + production management Tech Stack: React, TypeScript, Vite, Supabase, Edge Functions, Capacitor, iOS, Android I am looking for a serious, reliable developer or small technical team to help manage and complete my existing platform. This is not a simple landing page or small app. The platform already exists as a production-style web application built with React, TypeScript, Supabase, and edge functions. I need someone who can help stabilize, manage, and finish the mobile app layer using Capacitor, i...
I want to build a clean, intuitive mobile app where users can browse and buy second-hand clothing—everything from laid-back tees to smart blazers. Because the catalogue will be a mix of both casual and formal pieces, the interface should let shoppers filter quickly by style, size, brand, price, and condition. The app needs to run natively on iOS and Android, sharing as much code as practical (React Native or Flutter are fine, but I’m open to your recommendation). I’m not in a rush; quality and maintainability matter more than speed, so we can agree on realistic milestones together. Core flow: • Seller uploads photos, adds basic details, and sets a price. • Listings appear in a scrollable feed with search and advanced filters. • Buyers add items to a c...
I need an end-to-end SEO and ASO partner for my fintech product. Before we touch any keywords, I want a clear audit of everything already in place—from on-site technical health and backlink profile to our current App Store and Play Store listings. Scope after the audit • Apple App Store and Google Play Store optimisation: metadata, screenshots, A/B tests, localisation suggestions. • Web SEO focused on Google and emerging AI search engines: content gap analysis, schema work, and a roadmap to strengthen topical authority. • Unified keyword strategy so the website, blog, and both store listings reinforce one another. • Tracking framework (Search Console, GA4, App Store Connect, Play Console dashboards) with agreed KPIs for organic traffic growth. What I&r...

I need a dependable partner who can safely add a batch of genuine-looking, five-star ratings and short, upbeat comments to my iOS app. The goal is to nudge the app higher in Apple’s search and category rankings, so every review must feel organic, adhere to Apple App Store policies, and focus on general positive impressions rather than feature requests or bug reports. Country target : Brazil Deliverables: • A predefined number of 5-star ratings paired with unique, concise positive comments • Reviews submitted from different devices/Apple IDs to avoid detection • A simple report (date, country, review text, and screenshot) once each review is live Acceptance criteria: All reviews remain visible after seven days, show on the public listing, and my developer account ...
I’m ready to get six apps live—Store, Driver, and Customer versions for both Android and iOS—and I need an experienced app-store specialist to handle the entire submission workflow. Scope of work • Android: Upload three AABs, set up a Closed Testing track for 12 email-based testers, collect and address any show-stopping feedback, then push each build through Google’s review until they are fully released. • iOS: Prepare three builds for App Store Connect, configure TestFlight as needed, and shepherd the apps through Apple’s App Review. • Listings: Write clear, keyword-rich descriptions for all six apps (English), fill in mandatory metadata, and ensure each storefront meets current policy guidelines. • Compliance & assets: Flag any...
The code is done and fully tested; now I need it live in the Apple ecosystem. The app is a Business/Utility tool and is ready for submission, but I do not yet have an Apple Developer account. Here is what I expect from your side: • Guide me through enrolling in the Apple Developer Program, including any D-U-N-S or legal entity checks. • Create the necessary certificates, identifiers, and provisioning profiles in App Store Connect. • Build or verify the release archive in Xcode (or the equivalent framework I used) and upload it to TestFlight for my final sign-off. • Complete the App Store listing—screenshots, keywords, privacy details, and compliance forms—so that the app passes Apple’s review and appears publicly. Acceptance is met once th...
I’m running several CPA campaigns that credit only when a user located in the United States or the United Kingdom installs a list of specific mobile apps I will supply. The offers are strictly “app-download” conversions and they track on both iOS and Android, so you’ll need access to real devices (or a compliant emulator that the network recognises) on each platform. Here is what I need from you: • Take the list of apps I provide and install each one from the official App Store or Google Play while connected through a genuine US or UK IP address. • Open the app after installation and complete whatever initial action the network requires (usually just the first launch or a short sign-up) so the conversion fires. • Capture a dated screenshot of t...
I’m ready to move my concept for a utility-focused iOS application from idea to a polished product on the App Store. The core goal is a fast, reliable app that solves a single everyday problem elegantly on iPhone and iPad. Here’s what I need from you: • Full native iOS build in Swift or SwiftUI, following Apple’s Human Interface Guidelines. • Clean, well-commented source code stored in a Git repository I can access at any time. • A concise README explaining build steps, third-party libraries (if any), and configuration. • TestFlight-ready build plus everything required for App Store submission: screenshots, plist settings, and compliance notes. I will provide wireframes, the precise utility logic, and any required assets once we kick off. Code ...

An all-in-one utility application is needed for my Google Play Console. The core idea is simple: bundle everyday helpers such as a calculator, flashlight, and any other lightweight utilities you can fit into a single APK while keeping the interface clean and minimalist. Key objectives • Android-only build (latest stable SDK, minSdk 21 or lower if practical). • Minimalist UI: no unnecessary animations or heavy graphics; flat colours, intuitive icons, and a straightforward navigation drawer or bottom bar. • Features to start with: calculator and flashlight. If you can squeeze in one or two more micro-utilities without bloating size or time, propose them. • Final deliverables must be Play-Store-ready: signed AAB, keystore file, clear versioning, privacy-policy l...
I have two Android applications that have already cleared the initial Google Play review, yet each time I push them from Testing to Production they bounce back and never make it to a public release. I need a seasoned Android developer who can dive into my Play Console, pinpoint exactly why Production keeps failing, resolve every policy- or compliance-related snag, and steer both apps all the way to “Live” status. You’ll get full console access so you can trace release tracks, examine policy warnings, crash reports or content issues, and apply the fixes directly in the code or the store listing. Once the root causes are handled, you’ll prepare the next production submission, respond to any reviewer feedback, and stay on the case until both listings are publicly avai...
