Follow your friends' pace in real time. See your progress for the week and check who trained in the last 24 hours. Instant visual motivation.

Your complete profile: attendance calendar (heat map), total check-in count, likes received and your personal gallery of physical progress.

Short streaks, kept week after week. That's what consistency actually looks like.
“I used to train for a week and then disappear for two. Now I close five days in a row most weeks, because whenever I feel like skipping I remember I'd break the streak.”

5-day streak
“What changed for me was seeing the attendance calendar filled in. It's that simple: when a gap shows up in the week, I train.”

6-day streak
“I use it more for the group of friends than for the competition itself. Knowing someone will see whether I trained today is motivation enough.”

The app was designed for people who train better when they can see their frequency, healthy comparison and small daily milestones. Every workout becomes a simple entry, with a date, an optional photo and points to track your own progress.
You can revisit previous weeks, spot days without activity, see who trained recently and use the monthly ranking as a nudge. The point isn't to reward perfection — it's to make repetition visible.
Your profile gathers all your entries and keeps your progress organised in one place. The privacy page explains which data is used to keep your account, history and social features running.
Tips, strategies and science to help you stay consistent.
