19 June 2017: seems to be working fine again now. Hanging since the last update. Battery history not working (OnePlus 2)
Been using it for almost 2 years now and it's a really good app. No issues whatsoever. Highly recommended!
Needs to restart itself after an update.

Irreplaceable Indispensable Essential (insert adjective) 👍 Absolutely love this widget and it's notification info. I only wish it's notifications skin themed according to the apps style chooser. That white is crucial on a Blacked out OS... If that could happen this would truly be a 360° perfectly well rounded application. 👌 currently only way I've found to blackout notification is run classic with chart on, set it to high priority. But that's a bit heavy just for dark notifications, but is what it is. Please make notification themeable!
I really enjoy using the app, especially the sleep/night mode. It gives one so much more battery time. It's survived 3 mobile cell phone telephones & 4 iterations of Android (Jellybean through Nougat).
