Heart Rate Tracking and Leaderboards for Gyms and Studios
Commercial ANT+, Bluetooth and Apple Watch receivers that put every member on the board
NPE receivers pick up heart rate and sensor data from every member in the room, whether they wear a chest strap, an armband or an Apple Watch, and send it over your network to your leaderboard, class display or software. They work with leading group training platforms or with your own app through the NPE API.
How it works
-
1
Members wear what they already own
Any standard ANT+ or Bluetooth heart rate monitor works. Members with an Apple Watch use the heartbeatz Connect Pro app, so they don't need a separate strap.

Data flows to your leaderboard
Receivers send data over your network to platforms such as Swarm and HeartZones, or to your own software through the NPE API for .NET, iOS and macOS. See all supported systems on our Integrations page.

Pair members in seconds
The Pairing Pod reads the ANT+ ID of a member's sensor so staff can assign it to the right person on the leaderboard without guesswork.

Yes. With the heartbeatz Connect Pro app, GEM3-PoE connects up to 15 Apple Watches per radio directly, and HÛBB adds up to 15 Apple Watches to an existing WASP system. Learn more about heartbeatz.
Which leaderboard software works with NPE receivers?
NPE receivers power platforms including Swarm and HeartZones. Developers can also build their own leaderboard with the NPE API for .NET, iOS and macOS. See the full list on our Integrations page.
How are receivers installed?
GEM3-PoE and WASP-PoE4 are powered over your Ethernet network and mount in a standard junction box behind a double wall plate, such as our White Dual Gang Box.
