Ratings and reviews

I love this app. I've used it across multiple generations of phones, mostly for the widgets... I love the fact that I can set a battery temperature alarm. But I would like to set a battery temperature alarm for low temperatures, not just overheating, but also under cooling... All this would require is changing the equal or higher sign to equal or lower. But unfortunately I cannot change that symbol. It allows setting very low temperatures, but then the alarm is always on.

Despite testing all the different current monitoring options, the figures this app displays were always hopelessly wrong - I used an actual power monitor in-line with the USB cable to measure the power being supplied, and they were not even close.

edit: manually setting to ua fixed ma reporting This app has stopped reporting the correct charging MA. It is now doubling everything so instead of showing a charging rate of 1800ma it shows 3600ma. This is making a mess of the calibration page as well since it thinks my battery is now holds over 8000mah. Also the full screen ads are getting out of hand. Sometimes there is no X to click on to close them. I have to hit home, then recent apps, close the app, and reopen it to get the ad to go away
