### 1/5 — Connecting

*2024-06-21, version 1.1.1*

Sometimes connects sometimes it takes ages. Have tried all things to fix it. Reset battery, re install app. Tried different phones. Will be going back to shop to see if there’s a fault

### 5/5 — Single fin Travellers

*2023-07-06, version 1.1.1*

We find this app very useful. Easy to connect and run. Tells you everything going in and out of your battery. We are running the 135ah batt and have had no issues at all. Only using roughly 20amps every 24hr period to run the 80L Engel fridge. 

Only this I could recommend to this app is to install a option to view your stats in a graph form, from what’s going in and what’s came out, just so you can monitor it all down to a tee. 

Cheers Hardkorr 

Give us a follow @singlefintravellers
