Usability - the base for success

Downloading health apps isn’t enough to drive impact. Users need to see a benefit, be engaged and stay interested enough to actually use them. Easier said than done; most apps and especially health apps struggle to achieve user engagement and retention.

juli was co-designed with participants, leading to a unique combination of retention elements such as gamification, reward systems and in particular a great usability for data capturing.
