Volt Battery Health Widget

Developer reply

Thanks for sticking with it, and sorry 1.2.1 didn't fix it. 1.2.2 is on its way and reads voltage from two-cell batteries like the Nord CE5's. If the card still shows no voltage, it will display the raw value your phone sends ("Unrecognised: ..."). A screenshot to support@mtgtechnical.com would let us fix it for good.

Thanks for trying Volt, and sorry the locks were a let-down. Everything it measures is free and stays free: battery health, capacity, temperature, voltage and the full measurement log. Only the five home-screen widgets are paid, a one-off purchase with no subscription, so you can check the figure is real before paying anything.
