For independent gyms & training studios
Heartstream shows the live heart rate of everyone in your class on a TV, color-coded by effort zone. Members see their effort and push harder. Coaches see the whole room and run better sessions. The big-screen group-training experience — without proprietary straps or per-member fees.
Works with standard chest straps your members may already own — Garmin, Wahoo, and any other ANT+ or Bluetooth sensor.
How it works
Members strap on, walk in, and appear on the screen automatically. Updates are instant — the tile changes the moment the heartbeat does.
Any standard heart-rate strap or armband works — the Garmin or Wahoo sensors many members already own, or straps you hand out at the front desk.
A palm-sized receiver box plugs into a power outlet in your gym. It listens for every strap in the room and matches each one to the member's name, photo, and personal heart-rate zones.
Any TV or screen with a web browser shows the grid: one color-coded tile per member with name, live BPM, and effort zone — readable from across the floor.
Why gyms add it
When your name is on the wall, you don't coast. Members chase their zone, compare effort honestly, and leave knowing they earned the session — the experience that keeps them renewing.
One look shows who can push, who needs to recover, and who is quietly redlining. Coaches cue by real effort instead of guessing from faces.
No proprietary straps to buy, no subscription per member. Heartstream is open: standard sensors, your hardware, your data.
Built for
Everyone sees who actually hit the target zone in the work block — and who has more to give in the next round.
Catch members going too hard too early and keep long efforts in the zone where they build fitness instead of burning out.
Zones are personal — 80% effort looks the same on the screen for a beginner and an athlete. Everyone trains together, each at the right intensity.
What you need
Any screen with a web browser works — a smart TV, or any TV with a cheap streaming stick or a connected computer.
A small receiver box (a Raspberry Pi with a USB antenna) that we configure for you. Plug it in, connect it to your network, done. One installer covers everything — easy to roll out across multiple locations.
Members bring their own ANT+ or Bluetooth sensors, or you keep a set of straps at the desk as a rentable extra.
FAQ
No. Heartstream reads standard ANT+ and Bluetooth heart-rate sensors — the chest straps and armbands sold by Garmin, Wahoo, and other major brands. There is no proprietary strap to buy and no per-member subscription.
A TV with a web browser and the Heartstream hub — a small Raspberry Pi receiver with a USB antenna that plugs into a normal outlet. We deliver it pre-configured; setup is plug in, join your network, open the dashboard.
No per-member charges and no closed ecosystem. Heartstream works with sensors members already own, runs on your own hardware, and your member data stays yours.
The dashboard runs on your local network, so live heart rates keep streaming even if the connection blips. Internet is used to sync member profiles, and the system retries gracefully if it drops.
Each strap is registered to a member profile once — name, photo, and personal heart-rate zones. From then on, the member just puts the strap on and their tile appears automatically when class starts.
