Revised... I decided to rate this 5★, because it has many features, options, and stats. The Developer has email support w/quick response time. Also shows interest in user suggestions... However, it could use a couple of options. The weekly subscription is a negative, but is offset by watching a 30sec video, which removes ads for 24hrs.

Look, the app is great. My problem is the payment option. I always support the devs, I always buy apps. But $1.99/mo with no lifetime option? It really sucks. I have never seen a remotely similar model with other utility apps in similar categories. Please give us a lifetime option, or at minimum an annual option. This is important because the app is honestly too annoying with ads enabled. I'm currently on the monthly subscription, but now you know why I'm 3/5 stars

Hello, you don't need to pay anything to use the application. It's completely free, also no locked app features. Payment is there only if you want to support my work and nothing else. As a return you'll have ad free app. If you hate ads and won't pay there is free way (24h sub), unlimited times. I think it's fair and correct, if you agree, give 5😊

Very good details. Only issue is the fact that during normal charges (over 80) and longer than 8 hours you state it as a over charge. Overcharging is impossible during normal charging using the specified charger and cable. The device will not allow the battery to accept any more current or voltage. It will run off the charger untill the battery voltage drops below a set point then it will recharge it back to full. This can take several days.
