User reviews

No pairing with OSTC+

I tried for hours to pair my OSTC+ with my iPhone, without success. While the app finds the OSTC through Bluetooth, it never manages to establish the connection.

Ok mais est-ce bien utile ?

Pour moi elle fonctionne bien
Elle permet entre autre la mise à jour du firmware ok
Mais pourquoi ne pas y inclure l’extraction des plongées et constituer un carnet pour exploiter courbes de décompression ?

Pas intéressant

Je ne trouve pas l’application intéressante pour moi.
L’application plante avec mon ostc sport, dommage.

Parameter Error ... is nix gut 🤔😢😢

... muss ich so leider auf dem ostc lesen. 🤔
die app schmiert sofort nach dem vebinden mit dem ostc ab und der braucht eine gefühlte ewigkeit um sich aus dieser misslichen lage zu befreien. ist hier nachbesserung angedacht oder gar schon licht am ende des tunnels zu sehen?

Perfekt!

Einfach, übersichtlich, gut:
Seit dem Update klappt‘s auch mit meinem „OSTC Sport“ und mit iOS 13.5 !! 👌👌👌DANKE Euch!
