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.

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.

I really enjoy your app, thank you! Good information to stay on top of my battery health and I like all the helpful hints offered as well. I also like how you're continually trying to improve the app by getting user feedback!

Pro app no ads, the app is the Best battery manager I've used in all my time using Android. My only recommendation allow white list of a certain app or apps if you enabled data saver to not sleep those apps

I wish the notification for charging threshold can use custom ingtone or custom a tone. I always missed to charge 80%. Overall this a great app. Good job!

Works great. Accurate with a lot of info. I just wish there was a one-time purchase option. I generally refuse to subscribe/rent software, but if the yearly amount was less I would make an exception for this app.

5+ stars for sure. It shows phone charging information accurately. Also the battery health is 99% accurate. Also it shows charging speed (in Watts) is a charm. Keep it going developers.
Keith Kramer
I really like this application. Over the years of using Android I have tried many battery monitoring tools. This one has a great UI, and provided the data I want in a easy to read format. Thank you
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
