First off, this app is very easy to use, and is quite handy to remotely monitor charging while at the flying field and away from my charging station. As the previous reviewer stated, this app needs to have notification functionality. This app does not show up in the notification settings screen on my iPhone 6S, therefore, you cannot set it to alert you with a notification tone when charging is complete, or when an error condition occurs. Also, I think the bar and graph screens are superfluous; I would prefer that the main monitoring screen during charging have the individual cell data added at the bottom of the screen (as on the bar screen), that way you can see all of the main charging info (current, pack voltage, time, temp, etc.) and the individual cell voltages, as well as the high-low-difference data, all on one page. Great charger (X2 AC Plus) and thanks for the app, Hitec!

Needs alert to app when charging is done, or when error occurs during charge.

Can’t find charger
