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
Tom D
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.
Dave
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!
Shawn
Good app, you need to be rooted to use it to it's full potential. You should add a way to support the app with a one time purchase "pro" version instead of the subscription model.

Tried many of these proved to be the best. An application that makes it worth unlocking the bootloader and routing your phone. Battery life has increased significantly.
Subhanshu Mohan Gupta
Deep sleep doesn't work sometimes. Please fix this. And also please add an online backup option for all our charging and discharging records so that we can't lose our records even after removing the app.
Nahid Hasan Riad
A great battery app. The notification details. The protection features. The optimization. Evrrything works fine and the reading is accurate too. Definately recommending who want to save and properly use their battery.

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!
Toby Pollock
It includes everything I want. The battery status notification shows the discharge current and temperature, very useful for monitoring while using another app.
