Ratings and reviews

Gimme Data! If this sounds like you, check out this app! It shows a wealth of information about your device. I seem to get caught with an overheating phone occasionally, and this app offers a floating widget showing the battery temp!

this app gives really good insights about your device and its in detail. I figured out cpu usage from this app and found there were certain apps I was using that had some services running that were occupying and due to that CPU was at high usage.

this is a simple diagnostics app to check your device is working optimally. it works perfectly, giving detailed and descriptive insights into your device metrics. I think the upgrade banner is a little strong on first opening, but you can skip it before buying after trying it out

What’s new

- Added advanced battery health analysis
