This used to be a good app. However a recent update made it much worse. You used to be able to find out the number of charge cycles you have accrued on your battery. The new update removes that which is one big reason why I bought this app in the first place.
The app also seems much slower and laggy when switching to the other tabs to see other types of data. The screen that displays the capacity is now constantly refreshing and gives me the sense that I cannot trust it anymore.
I would avoid this app until these issues are fixed. Especially since it is not free.
