Progress you can see, measurement by measurement.
A web app for the clients of a fitness platform: weight and body-fat dynamics from measurements, weekly trends and recommendations, in a mobile-first interface that feels like an app.
- trends in one view: weight and body fat

The challenge
A coached fitness programme depended on the coach collecting reports and turning numbers into progress by hand. The goal was a digital curator: clients report in a minute and see their own dynamics, and the programme changes from week to week without a developer.
What we built
We built a mobile-first web app that also opens as a Telegram Mini App. Clients fill in a daily report (weight, steps, training and nutrition imported from a food diary) and a weekly one with measurements. The app calculates body fat with the US Navy formula and draws weight with a moving-average trend. Admins build programmes from weeks, tasks and norms, and an AI assistant writes a daily analysis for every client.
