Put your training where your mouth is.

PropStar Fitness turns your own physical performance into a competition with your friends — recurring group challenges, scored automatically from Apple Health.

How a group challenge works

Start a group and invite the friends you actually want to beat.
Everyone sets a goal and a window — distance, steps, workouts, active energy.
Apple Health scores it. Hit your goal and you keep your entry — plus a share from everyone who didn't.

Because meeting your own goal always returns your entry, a group challenge comes down to one thing: whether you did the work. There's also a head-to-head format if you want to call someone out directly.

A contest of endurance, not of chance. Outcomes are decided solely by each participant's own verified physical performance. No random draw, no house, no wagering on anyone else's game.

Stars are play currency. They have no cash value and cannot be redeemed, withdrawn, transferred, or exchanged for money or anything of value. There is no cash-out — it's for bragging rights.

Your health data stays yours

PropStar Fitness reads aggregate workout totals — duration, distance, steps, active energy — and nothing else. It never reads your routes or location, never writes to Apple Health, and never uses health data for advertising. Read the privacy policy for the full detail.
