Adding Body Composition Tracking (Body Fat & Muscle Mass) to Yazio

Dear Yazio Team,

I am a sports scientist and a regular user of your app, both for myself and for supporting my clients in nutrition counseling. First of all, I’d like to say that I really enjoy using your app – it is already very comprehensive and helpful.

However, I would like to share a suggestion that I believe could take Yazio to the next level: the possibility to track body composition.

In my experience, focusing solely on absolute body weight can be misleading. Many people exercise regularly, pay close attention to their diet, and visibly improve their physical shape, but the scale often shows little change. What truly happens is a reduction in body fat and an increase in muscle mass.

If Yazio users could see these changes reflected in the app, it would be highly motivating for them to continue. On the other hand, if they only see their body weight, they may feel frustrated despite their hard work.

Therefore, I would love to see an option to enter and track not only body wei
