Been using for over 4 months, it gets the job done. You can set the custom level for either alarm at 5% or 5° increments, & how much nagging you desire. There is a short FAQ Help. 🙂 But the voice alarm is TOO LOUD and the volume setting does NOT work, & it sounds BOSSY & frantic. 😱 It makes me jump. Possible deal breaker❓ A soft, calm voice option would be nice. The battery & temperature charts need further explanation.... what values are they recording❓ (+ This Edit box SUX‼️❗)

I like this app. There needs to be an ad-free option, with a one-time small purchase fee, to remove the ads. Have only been using for a short time; it's functioning good so far. Especially, eliminate adds that popup and fill the whole screen when the app is not open. Ads equal 4 stars.

The best app out there for keeping your battery between 30 and 80 percent. Unfortunately, the notifications can be annoying. I turn off voice and alarm to just get text-like notifications. Most importantly, the notifications don't work consistently. I usually don't get the 80 percent notification.
