This is a very good app that will help you maintain positive long term battery health for your mobile device. The ads are not annoying. The developer makes it very easy & gives you options to remove ads. The information is easy to understand & the app is well designed. There is one problem though & it's a big one. There is no audible alarm when your charge gets to a specific %. There are notifications & vibrations but they do not grab your attention. Accubattery does this better.

Very beautiful UI, simple and clear information and gives some good suggestions on maintaining/improving battery life. The monitor indicators on the top of the screen and the battery statistics readouts on the screen is clear, not in the way, and I've reffered to them rather often, nice since I don't have to look. It's a keeper.

Work great so far. The app gives you real options to control the way your phone charges and discharges. It allows you to turn off all of the tracking devices which I was unaware of. They take a good bit of power. The only issue is from reading the comments, I thought it would be a one-time payment and not a monthly subscription. I'm not fond of monthly subscriptions.
