Surprisingly Useful, Not Just system Monitor

Downloaded it to check battery and RAM, but ended up loving the real tools. The home screen widgets show CPU & network without even opening the app. The Picture-in-Picture mode is great while gaming or on calls. Battery temp and cycle count were accurate, and it helped me catch another app draining my battery for no reason. One of the few apps I actually use daily, and the Lifetime price is very fair compared to others. Recommend it to anyone who cares about their device’s health.

Clear info about your phone

The interface is clean, the information is easy to find, and I ended up using it much more than I expected. If you're buying or selling a phone and want a better understanding of its condition, this app is definitely worth having. Highly recommended!

Very useful app!

Really useful utility app for checking device performance. I like how it shows CPU and system info in a clear, simple way without feeling cluttered. It’s handy for quickly understanding what’s going on under the hood, especially when something feels slow or off.

Love this app

Never thought I could see so many metrics of my iphone so easily. Very nicely designed app. Would love to go Pro for sure.
