Nice Things About Us
Dio Tony
Still exploring the whole functionality but it has been great experience so far. Thank you for your hard work Wishing that it could directly make a charge cut off but it seems like this is out of the scope
SARRAF
I'm honestly impressed at how often this app gets updated. And with each update, it gets better and better. The UI gets even more beautiful with each update. I have replaced my old battery tracker app and doze manager app with this one app. And it does more than those two combined! Absolutely love it.

1. It closes itself and i have to run again and again. If android closes it, then run it again by asking another permission from us while installing your app. 2. Why you read Android Device Configuration Service? You steal all our private data! 3. Your answer was not customer friendly.
Michael Clark
Great App! I have a smaller phone with minimal battery life so being aware of all the aspects of my battery are key in maintaining optimal battery health. This App has everything and the ads are discreet and don't interfere with the App operation or function. Excellent!
Savita
Very useful, user friendly. One suggestion. Discharge rate showing correction reqd. MIN shows larger rate of discharge e.g. -657 mah and MAX shows lesser rate of discharge e.g. -156 mah Its because of negative number . Also give another option of one time payment alongwith monthly, weekly options.
João Pedro
Very complete interface, lots of monitoring to improve battery life. Just amazing. Also liked the way ads are served, in an on demand way for free users. This non intrusive way is much more comfortable for users, trading off revenue. But UX is extremely improved this way.

This app is excellent! It provides detailed battery health information and tracks battery usage very well, making it highly reliable. It comes with many useful and important features that work great, and it's very easy to use. I highly recommend it to anyone looking to monitor and manage their battery effectively.

The overnight summary is fairly useless without information about what caused the wakes. Ok, so it woke up 12 times. That alone is not actionable.

I love it. Please add an option in which the app can automatically turn off the wifi when it's disconnected from a known network, also another good idea you should take into consideration would be to give the option to make the phone call you instead of normal notifications.
