COSS develops apps and clockfaces designed for use with the Fitbit platform.
We have many years of experience in development for the wearable and mobile platform. We develop for iOS, Windows and Android.
We hope you enjoy our clockfaces and apps which are solely designed for use with Fitbit Ionic, Versa, Versa Lite, Versa 2, Versa 3 and Sense plus upcoming new models.
