App functionality:
Main Screen is configurable and will show The state of Charge, Voltage, Charge and Discharge current, The used capacity in Ah, Projected time until full and empty, finally also the temperature inside the battery. 
You can retrieve cycle count as well as the calculated capacity. This is improves the second hand value as well as giving you immediate information regarding any capacity loss due to for example low temperature.
Temperature is configurable (C/F)
