### 1/5 — Requires account for no reason.

*2025-04-25*

There is no reason to require an account and when Rattan stops supporting it, then the bike is junk.

### 3/5 — Fonctionnalités disparue

*2024-12-28*

La fonctionnalité position du vélo sur une map ainsi que la fonctionnalité GPS ont disparues. Une application qui peut avoir du potentiel mais qui n’est pas régulièrement mis à jour.

### 3/5 — Half works

*2024-09-20*

No way to subscribe to get navigation function.

### 1/5 — App inutile

*2024-06-29*

App inutile. Non si possono nemmeno cambiare le impostazioni della bici dalla app…
