Apple Watch Support

Love the app but 2 request. Can you please add Apple Watch support to this app? I use Ride With GPS and I like to keep my iPhone on that app so it would be nice to see the CarBack info on my watch. Additionally, can you add support for Ride With GPS so I again I can see car data within the Ride With GPS app.

Radar

A veces no detecta coches cuando se vale en Grupetta o los detecta muy tarde.

Funciona perfectamente

Corregidos los problemas de desconexión. Una vez actualizada, no se desconecta y se puede usar a la perfección . Un 10
AGAitor Gurpegui

Decepcionado

Tras la actualización del firmware el botón del Carback no cambia los modos de luz y la app no conecta con la luz. Se queda en bucle pasando por bluetooth las preferencias de la configuración sin conseguirlo.
