The app in action
A feed with your crew's workouts, live challenges, your progress and your achievements — all in one place.
The whole group seeing who trained today
A challenge is a group with a goal: how many workouts per week count for points. Every check-in shows up on the feed instantly, and the ranking updates itself.
At the end of each week and month, everyone gets a recap: who climbed, who dropped and who owes workouts.

What people say after a few weeks of challenges on Treinou.
“I was the king of 'starting Monday'. My group created a challenge and now if I skip a workout I get a screenshot of the ranking. It worked.”
“The weekly recap became an event. Every Sunday we check who climbed and who dropped — and nobody wants to finish the month last.”
“I use it to track my PRs and measurements, but what really keeps me going is the streak. 40 days and counting.”
