TestMu AI (Formerly LambdaTest)Reviews of testmuai.com

Best app for Mobile app testing. I am using from last 2 year and I have great experience with this tool.

We use testmu AI strictly for manual real device testing for client projects across different regions. The biggest issue has been reliability. Devices show as available in the dashboard, but when we try to start a session we frequently get a “Device not available” error. Sometimes it works after multiple retries, sometimes not at all. We only do Manual testing for our clients, so availability is critical for us. I can understand occasional capacity constraints, but the frequency, especially for newly launched iPhones and Ultra devices has increased significantly compared to when we started. Free trial also showed so much more. For a paid service, device uptime is bare minimum.

It is easy to register for exams, provide learning material, step by step guide. Just one thing, Certificates not received even after 12 days of exam.

Great experience, very sopprtive people.

LambdaTest has been a great solution for testing websites and applications across multiple devices and browsers. It completely eliminates the need to purchase physical devices, as everything is available on the platform. The experience has been smooth and reliable, and it has significantly simplified our testing workflow, highly recommended for teams looking to save time and resources.

I’ve been using LambdaTest for several years to run automated cross‑browser tests, and it has saved my team a lot of time. The platform is easy to set up, integrates smoothly with our CI/CD pipeline, and the range of browsers/devices available is impressive. What stood out most was their customer support—quick responses and clear guidance whenever we hit a snag. Overall, LambdaTest has made our QA process more efficient and reliable. I’d recommend it to any team looking for scalable cloud testing.

Everything was super easy to use and navigate. I had no issues at all and rate the experience 5/5 stars!

Janky software. It showed my site's plug-ins were broken in windows pc, yet on my actual windows pc the plug-in were there and working. I canceled and asked for refund with no response, of course. Stay away from. You are better off buying the actual devices you want to test on.
