### 5/5 — Love this app with my caravan

*2025-10-10, version 1.1.13*

Awesome BMs manager

### 2/5 — Lacking in detail

*2021-11-04, version 1.1.8*

There seems to be a lack of information on the features available in this app. There are quite a lot of details but no explanation or information. 
On the plus side, the buttons which are self describing work - just no idea what the other features/buttons do or should do.  Eg what does night mode do?
