Turn your Apple TV into the command center for your gym sessions. HartCore TV is a passive display and session host for group workouts —
connect your iPhone and Apple Watch to see live stats, heart rates, and leaderboards on the big screen while you lift.
Built for training together:
- Live leaderboard — see every lifter's reps, sets, and volume in real time
- Heart rate & activity rings — cinematic display of everyone's effort at a glance
- Room codes — partners join in seconds with a 4-digit code, no accounts or logins
- Workout summary — celebrate total volume, PRs, and ring closures after every session
- Zero logging on TV — the TV shows; your iPhone and Watch track
How it works:
1. Launch HartCore TV — it auto-advertises on your local network
2. Open HartCore on iPhone, tap the Apple TV icon, enter the room code
3. Start your workout — every rep, set, and heartbeat streams to the screen
Perfect for home gyms, garage gyms, partner workouts, and gym crews. No subscription. No internet required. Works entirely over local
Wi-Fi.
Requires the HartCore companion app on iPhone.
