About this app

Nowadays almost any charger can plugin to any mobile device. This app checks if a charger is providing the sufficient power to charge the connected device quick and right. You can see the amperage live in mA (if your device supports this). Connect your charger to get the battery charging current or disconnect it and get the negative discharging current and be informed for your systems consumption anytime. Keep your battery in good condition and your device up and running.

Ratings and reviews

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.)

Good app for quick numbers. I have a wattage reader, close enough with negligible variation. Would like an option to toggle the milliamp reading to amps or watts instead of some mental math. Solid app.

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!
