Aggiornamento in peggioramento
Preferivo la versione precedente che permetteva di condividere con maggior facilità la posizione e le navigazioni con gli ospiti e chi restava a casa.
Imposible realizar la suscripción en la aplicación y tampoco en la web
Intento renovar la suscripción y es imposible la aplicación no te deja y en la web no aparece en ningún lado donde realizarla. Mandas mensajes y no te contestan y si lo hacen no te solucionan el problema…. El primer año funcionó bien pero ahora el servicio no es bueno. Horrible
No manuals
With the new update, my manuals disappeared. Update - the problem has since been resolved. It took a couple days but manuals are now back. Overall, the app is a handy tool for monitoring your boat while away. It’s nice to have the manuals available, but a little slow in loading and navigating back and forth. Other than that, I like it.
Werkt niet op mijn iPad IOS 15.6
Klik op plus om boot toe te voegen en de app sluit zichzelf. Werkt wel op mijn iPhone.
Verbeterpunten
Redelijke app, wat ik alleen heel jammer vind is dat er geen mogelijkheid is voor het schrijven van een journaal. Dan kan je je gehele logboek de deur uit doen. Ook vind ik het stoppen van een trip vrij omslachtig (als het al lukt).
A lot of features
I love the variety of features this app provides: tracks, sensor data, switching, manuals...
Service partner was incredibly slow
Took over two months for the service partner to register and enable the product - u need a way better program. This is negligence for a brand new boat that I paid a premium price for including this product.
Great app
It is great and gives you comfort on your boat
Complaint
I require to have all my sensors showing Not 4 at a time
Assistenza inesistente
Quando funziona è valida, il problema è che l’allarme sonoro su iPhone non va , e poi funziona a periodi, cercato di risolvere con chi lo ha installato e tramite Sentinel, ma nulla, si passano la palla uno con l’altro è non funziona.
