I've used the all about 6 months and totally rely on it. Well done developers and thank you! I don't charge my two phones overnight because they only need about 30 mins to reach 100%, so I plug them in each morning and the alarms sound at 90%. No overheating. Easy to set up, flexible about when alarms should sound (ie set a minimum and a maximum charge %) and a nice summary after you've unplugged the phone, telling you how long it took you after the alarm sounded. Superb.

pros: Basic feature works reliably. cons: Uses 40% of the battery charge on my phone, just this one app. Can't stop the alarm while the phone is plugged in, so can't charge the phone above the high charge setting while the app is installed without the alarm sounding continuously. The alarm sound repeats until you unplug although you have set it to play once. You get a notification when you unplug and there is no way to prevent that - except sometimes you don't so it is unreliable for anti-theft.

Thank you for developing this app. It works perfectly on my S23 ultra. I've set my reminder at 25% and full charge to 85% and it works flawlessly. It allows me to choose from the full list of alarm/ringtones from my phones data bank and I can set both the reminder and full charge individually which I'm very grateful for. I can also set the volume levels of each alarm separately. My battery even seems to last even longer since I started using app. I really cannot recommend highly enough .
