A cardio game where your pulse drives the dungeon. Hit your target zone and your champion strikes. Drift out, and the run stalls. Real workouts, wrapped in pixel art instead of another bar chart.
No buttons to mash. The game reads your live heart rate and turns effort into action. Set the speed, incline, or resistance to stay in your target band, and your body does the rest.
Pick a dungeon and start moving. Your effort sets the pace.
Each dungeon has a target band. Match it and your champion advances and powers up.
Hit the perfect beat and the sigil locks for a critical strike and a big score.
Treadmill, bike, rower, or elliptical. If it gets your heart rate up, it runs the dungeon. Bring your own machine; the game reads your effort, not your equipment.
Live heart rate comes straight from Apple Health, so any Watch, or any chest strap that writes to Health, just works. Your zones are built from your own resting heart rate, not a textbook formula.
Read from Apple Health in real time. No extra hardware.
Computed from your own resting heart rate.
Every session writes back to Apple Health as a workout.
Each ability is tuned to where you sit in your zone. The app recommends one for every workout. The choice is yours.
Eleven biomes built by hand, four classes, and a fight that only moves when your heart does. Prop your phone on the console and go. No presenter, no leaderboard, no bar chart.

Just you, your machine, and your heart rate.
