How it works
One pet. The whole squad. Real workouts.
-
1Hatch
Start a squad of up to 8 friends, pick an egg and name your Buffin together.
-
2Train
Lift, run, ride, dance. Workouts sync from Apple Health on their own, including from your watch or band. Nothing to log.
-
3Evolve together
Every workout from anyone in the squad feeds the same Buffin. Show up together and watch it get absurdly buff.
Your watch or band counts too · synced through Apple Health
Watch- Health
Your squad, keeping each other honest
Nobody wants to be the reason Brutus is small.
Your Buffin belongs to everyone. When someone trains, the whole squad sees it. When the squad slacks, Brutus gets lazy.
He never dies. He just grabs snacks and waits for you to come back.
- maya just trained · Brutus +40 XP
- jake ran 5k · +55 XP
- sam hit leg day · legs getting thicc
- Squad goal this week: 4 of 5 workouts
Every squad names its own Buffin. This one's Brutus.
Skip leg day. We dare you.
Your Buffin's body follows your workouts. Skip legs and everyone will know.
Nothing dies here.
Busy week? Your Buffin just gets lazy on the couch. One workout and it bounces back.

Questions
The quick answers
Is it free?
Yes. Hatching, training and every evolution stage are free. Squad Plus is optional, and one person can unlock it for the whole squad.
When does it launch?
We're aiming for January 2027, on iPhone first. The waitlist hears about it first.
What about Android?
Android comes after the iPhone version. Join the waitlist and we'll let you know when it's ready.
Do I need a gym?
Nope. Any workout saved in Apple Health counts: runs, walks, home workouts, dance, sports.
Will my WHOOP, Oura or Garmin work?
Yes, through Apple Health. Turn on Apple Health sharing in the WHOOP, Oura or Garmin app and your workouts will count. We'll walk you through it when Buffin launches. Apple Watch workouts count automatically.
