units, time to charge or C rate

hi app easy to use and fast. A small thing and I don't mean to be picky. Is that the units for the charging current, "mA/h" which I think would mean "milliamps per hour" Ithinkshould just be "mA" , i.e. "milliamps". I don't mean to be picky. I just think people will notice that and worry that the app is not as good as it really is. Also, could you add a feature that shows how fast battery capacity is increasing given the phone type and the current going in and such perhaps the changing in voltage so we know how fast we're charging how long we'd have to wait with the charger we're using? thank you for consideration and for your work.

mAh is a measure of capacity; mA is a measure of current.

This app, as shown in the screenshots but just as bad in the app (erroneous "correction" to "mA/h"), displays a fundamental misunderstanding of electrical principles. "mA" is a measure of current, speed, power, like "miles per hour" (rate of change), whereas "mAh" is a measure of capacity, storage, energy, like "miles driven". I just came across this app to see the temperature of the phone/battery, but just couldn't give it a pass going this long without the author understanding the principles behind the app they wrote.

Good

I like this app. Seems fairly accurate to me, although some people may have had different opinions about that. I would like more is a stat showing how much time it’ll take to charge the phone completely based off how much power is left and the rate of charging. I would also like a stat showing how much time I have left before my battery dies based off the power usage (if charging at the same time, this will likely not make a be an issue assuming the cord and charger are alright, but a stat like this would be a good tell if your charger/cord/source of power is bad too). These are currently missing, but I feel they would be very useful, especially for those who are always on the go.
