User reviews

Been in use 5+ years

I use a LiFOS battery to power my amateur radio transceiver and a laptop for outdoor operating. I have used this iPhone app to keep an eye on the charge state of the battery ever since buying the battery in 2019. It works perfectly and has never given any trouble at all.

Underwhelming

Difficult to read dials, but always used to connect. Now doesn’t! Battery is visible and starts flashing as soon as open app, but nothing shows in app

Does what it should do.

If you want to know the general state of the battery, it works fine, providing all the information needed. It connects to the battery instantly, lets me know if the battery is charging, the level of charge remaining etc. etc.
I don't need a work of art, just info on my leisure battery, this app provides it. Excellent.

Poor

The scale of the dials is ridiculous and why not show digital number read outs instead?
