You'll be surprised by how gutless some of your chargers are and might buy better ones. This app is easy to use and read and provides the info I need about how the battery and charger are doing. (However, a minor bug afflicts the current version, causing both the drainage and charge rates to display negative numbers; the charging amperage should be positive. I tested on two separate devices. Don't let that deter you though. It doesn't effect the accuracy usefulness of the app.)

This app bombards you with ads while your are using it; while switching from the "Basic" tab to the "Advanced" tab, the ad was so aggressive, that at first glance I thought it WAS the "Advanced" tab! There are plenty of other apps in the Play store that offer the same features as this app, plus more, that will not harass you with ads while you're using it. You should definitely download one of those apps and not this one.

Dear Amanda, thank you for your toxic review. Luckily people have their own opinion, if you allow so, and they support my app. I have a unique feature, the shield widget, which you could just use and have the readings outside the app and thus without ads. I do not control the ads. I hope you understand that I have to get paid somehow. Thanks.

I used this app awhile back and it worked really well with a cheap Walmart phone that I had. But a few years later I come back to this app with the Galaxy S10 and it has told me that I had a negative charge when I was charging. At the same time I saw my battery percentage go up. so my thought was that the app was measuring wrong. Please fixed this! Update: Wait... I think this might have helped me actually now that I have plugged it into an actual wall outlet instead of a battery bank... Thanks!
