It does what it says and gives you the status bar battery stats icon in watts. I like that this app shows watts, as others will only show the volts and amps making you do the math in your head. It doesn't have a ton of annoying notifications and alarms. A couple things I'd like to see is the ability to change the temperature reading to fahrenheit, and I'd like to have the wattage and temperature both displayed. Also, the W under the wattage isn't necessary and takes up a lot of space.

I wanted to get a simple icon in my status bar to indicate whether my device is charging or not, as my OS configuration shows the battery percentage in the status bar but doesn't specify whether it's currently charging or nit. I thought this app had this capability, but it doesn't. To the dev: please add another "unit" in the settings for the charging status, thank you!

Good concept. The "W" readings when charging seem to be a bit off by 4-5w also a few app crashes.

Thanks for trying the app! If you are up for it (especially if you can collect logs), you can open an issue at https://github.com/dubrowgn/wattz/issues, and I'll take a look. If you would rather not, no worries and thanks again!
