From 79,439 reviews, clients rate our Mobile App Testers 4.9 out of 5 stars.I need a meticulous QA specialist to run a round of functional tests on our mobile app’s in-app navigation under iOS 26 with the system language set to Russian.

I have a brand-new social media Android app that needs a focused, 14-day quality-assurance push.

I already have the PickCab Partner Android app live on Google Play (). I now need two additions: 1. Integrate the Razorpay payment gateway end-to-end, handling order creation, callbacks, success / failure states and error logging, then pushing a new build to internal testing so I can see live payments working. 2. Add a real-time, one-to-one text-only chat inside the app so drivers and riders can message each other. Basic features I expect are time-stamps, typing indicator and push notifications when the app is in the background. You are free to use Firebase, or any solid alternative. No extra authentication screens are necessary; the new modules should plug straight into the existing flow. Deliverables: • Updated, well-commented source code with Razorpay SDK and chat module integr...

I need a sharp set of eyes to diagnose what went wrong and outline clear, actionable fixes I can implement right away.

What I expect from you 1. A quick but thorough audit of the account structure, ad sets, creatives, optimisation events, attribution windows, and pixel/App SDK implementation. 2. Identification of the most likely bottlenecks causing the zero-install outcome. 3. A concise report (bullet points are fine) with st...

I’m rolling out a web application with online payment capability and I need fresh eyes from Australia who can run focused functional tests on an iPhone. Here’s what I expect back: screen recording, plus a screenshot. I’ll provide a test account and tell you how to do it; you simply follow it, explore beyond it, and flag anything unexpected. Because regional factors such as language settings and local payment gateways matter, you must physically be in Australia and perform the test on an actual iPhone (no simulators). If that matches your setup, I’m ready to send credentials and get your first run scheduled immediately.

I’m ready to move my existing mobile app to the next stage by introducing two key capabilities: secure email-and-password sign-up/login and a fully functioning in-app purchase flow. The current build is stable but still lacks these revenue-driving and user-management features, so I’d like to fold them in without disrupting what already works. Scope • Implement robust user authentication based strictly on email and password, complete with validation, forgotten-password flow, and token-based session handling. • Integrate in-app purchases (consumables and/or subscriptions, depending on what the store guidelines permit) so that purchases are processed, verified, and recorded on the backend. • Refactor or patch any surrounding code that these features touch to ...
I’m organising a one-day fun run for about 100 participants and need a simple mobile app to capture the day. The flow is straightforward: • When a runner opens the app, the first of eight Google-Maps screenshots I provide appears. Swiping (or tapping “Next”) moves them through the remaining seven sections as they reach each checkpoint. • At every checkpoint they must snap a quick photo with the in-app camera—no gallery uploads—then confirm the picture before progressing. Each photo automatically tags itself to the corresponding checkpoint. • After finishing all eight points, users either: – browse every participant’s shots inside a shared gallery, or – if the shared gallery proves expensive to host, let me alone see th...

I need a straightforward Android utility that lets users browse, organize, and share files stored on their device.
