Didn't like the app
And now the company has gone poof!
Good App
App works as it should. Connects and displays battery info without an issue. Wish I could rename the batteries, and simultaneously see more than one battery.
A little wonky
We camped off grid for 2 days and the battery died. We thought we were at 87% when we left but with just LED lights, a bit of fan use, 10 minutes of heater fan use, and the slide out and in and out again, it died. Bringing it home and plugging into shore power, the onboard converter got the 100 Ah battery topped up again overnight and hopefully the Bluetooth module reset itself after the zero charge state. We’ll see how it goes. If it happens again, I’ll add a renogy or victron Bluetooth battery monitor.

Basic functions work well
If you just want to see SOC percentage, charge/discharge rates and time left to charge, then this app works well. They tried to include a lot of other data and graphs but they don’t work. For example the voltage display says my battery average voltage is “3.335 volts”. (Huh??) Also the graphs only update while you are looking at them. If your phone sleeps or your screen goes dark, then the graphs don’t update data. This makes them pretty much useless.

App doesn’t agree with charger
My app shows my batteries are fully charged, but the charger shows only 25-50% charge. 3 new batteries hooked up in series. Battery # 2 fully discharged according to app. Not pleased with purchase.
