Badly needs a calibration function.
It looks like the connection issues have been resolved with the latest update. Everything seems to work ok but the resolution on the voltage measurement is quite poor...it typically over-reads by around 250mV (against my lab cal’d dvm). If the developer could add a calibrate function in the app ot would get 5 stars!!!
The device doesn’t auto connect to Bluetooth for a good reason.... when connected it draws around 12mA from the battery, when not connected to Bluetooth this drops to around 2mA. So you don’t want it connected all the time like when you are in bed etc. Overall it is very good value for money, just a shame the accuracy is not a bit better.
