Circular Smartphone App


The Circular application provides the user with specific health and personal performance insights based on the monitored data. Firstly, the baseline data is established for the user. The collected data will be compared to the baseline by a dedicated AI engine that will then provide personalized advice to the user.

Circular is, first and foremost, a wellness and fitness device, and the application underlines this focus. The application offers a modular design for the features supported - the user can add and delete different modules. In the future, new releases of the features, so-called circles, can be added.
