From 66,216 reviews, clients rate our Mobile App Testers 4.9 out of 5 stars.Two Android apps are at the final gate for Google Play approval and need real-world shake-downs. With your personal Google account on an actual Android device (no emulators), you will install both builds from the Play Console’s internal test track, explore every feature, and capture anything that could trip the review team. Here is what I expect back: • A concise test report for each app covering core features, overall usability, and performance observations (loading speed, responsiveness, battery drain). • Clear, reproducible steps for any bug, crash, or graphical glitch, plus screenshots or short screen recordings when possible. • Confirmation that installation, first-run experience, login, and normal daily use feel smooth on your hardware. Everything should b...
Hi, I have an existing mobile app built with React + Vite + Capacitor + Supabase. The app is already mostly done, but I need help fixing some issues and completing it. Main problems: - Login not working correctly - Notifications not working - Profile images not loading properly - APK not installing on all devices I need someone who can quickly understand the project and fix these issues without breaking existing features. Budget is €100 fixed, so please do not apply if this does not work for you. Before we proceed, please answer: 1. Have you worked with Capacitor + Android builds? 2. Have you used Supabase before? 3. How long would you need to fix everything? I will only reply to serious and experienced developers. Thanks
I’m running a 14-day closed test on Google Play and need exactly twelve unique Android users onboarded through my invite link. You’ll share each tester’s Gmail address so I can whitelist them. They must be from real devices. Here’s the flow I have in mind: once you’ve assembled the group, send a joint introduction email—copying me—so I can distribute the invite. Testers simply need to accept the invitation, install the app, and keep it on their phones for the full two-week period. There are no demographic or location requirements; any Android smartphone user is acceptable. Verification is straightforward. On day 1 collect an installation screenshot from every tester, and on day 14 capture a fresh “still installed” screenshot. If anyo...

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...

My app’s core features work well, yet users still struggle to find their way around. I want you to refine the navigation so the overall flow feels natural and self-explanatory without touching or removing any existing functionality. The focus is squarely on navigation. I’m looking for an “introduction and easer to use without changing features” approach—think clearer paths between screens, logical menu placement, and cues that guide the user from one action to the next. I’m open to adding a lightweight onboarding experience (maybe a short step-through or similar) if you believe it will genuinely improve first-time adoption, but I haven’t committed to it yet. What matters: • Keep every current feature intact; nothing disappears or moves so f...

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 will be running a three-day, live course for an intermediate audience who already build simple Power Apps and flows but now want to master advanced app architecture, sophisticated Power Automate workflows, and the newest AI features such as CoPilot, GPT connectors and AI Builder. The emphasis is on business-process automation and data-driven reporting, so the material needs to revolve around those real-world scenarios. I need a fluent English trainer who can explain concepts clearly, handle ad-hoc questions, and supply polished slide decks, demos and hands-on lab exercises. Existing courseware, sample solutions and datasets are a major plus because the class should leave with templates they can apply the next day. Logistics • Three consecutive days, six teaching hours per da...

I already own a tweaked APK of AirAttack 1941 that links energy-recovery to gameplay speed, but it caps out too soon and crashes after extended play. I need you to rebuild the mod so I can push the action far faster—ideally up to 8× or beyond—while keeping everything rock-solid. Here is exactly what I’m after: • Deliver a new APK/APKS (no source code available) where a single in-game slider lets me select any speed from the normal 1× all the way to the top limit you can safely reach (8× minimum). • Energy-recovery must keep scaling with speed just as in my current build. • The game must remain smooth: no random crashes, freezes, or stutters even during long sessions or heavy effects. • Gameplay, graphics, and progression must ...
I need a simple Android application whose single mission is to let me run functional, manual tests against the login flow of any build I install. The app should present a clean checklist-style interface where I can: • launch the target APK or activity, • step through predefined login scenarios (valid credentials, invalid password, empty fields, network error, etc.), • capture notes, screenshots and pass/fail status for each step, and • export the results to CSV or share them directly by email. No automation is required; everything happens through on-device interaction so the tester keeps full control. I will provide the exact test cases and acceptance criteria once the framework is in place. Deliverables • Android Studio project (Kotlin or Java) ready to...

I’m preparing to roll out an Android application built for professional adults and would like a seasoned set of eyes on it before launch. I need an experienced Android developer—or an influencer who knows what resonates with this audience—to install the current build, explore every major flow, and deliver constructive, actionable feedback. Please focus on three things as you test: • User interface design: overall look, layout logic, and how polished everything feels on modern devices • App performance: startup time, memory use, battery impact, and any noticeable lags or crashes • End-to-end user experience: clarity of workflows, feature discoverability, and whether the app genuinely solves a professional’s day-to-day need Deliverables 1.
