App is ok but it's really not great. So many good ideas but they aren't fleshed out. Example: my phone turned off from heat. I'm curious what it got up to but the data only goes back to when it booted. And there's lots of other things like that. Some things have really cool graphs (even if the data ranges aren't complete) others have a completely different style that is almost useless because the bars in the chart are too large. There's no granularity to its data presentation. Hope it improves.

battery info page is in 24 hour format does not give option to change to 12-hour format. Subscription based apps are what's wrong with this world. I'd gladly pay $50 one time and pay it again for significant version upgrades (rather than incremental updates which should be included free from within one version) so that you only pay to go from version to version.

Thank you for the detailed feedback! I’ll consider adding a toggle for 12/24-hour display. As for subscriptions, I appreciate your view. I'm an individual developer and rely on them to maintain and improve the app daily. However, there is a free 24h premium option that can be used unlimited times. Have a beautiful week ^^

This app saved me from having to reset my phone! My battery started to drain rapidly after I was on a video call with my brother about a month ago, and I have no idea why. I tried everything short of resetting my phone, which I was just getting ready to do. I found this app and decided to try it, and it immediately fixed the problem, and it's working as it had been before what ever caused the problem. Definitely recommend this app, and I'm extremely thankful I installed it, and that it worked!
