OnBeat is a free iPhone app developed by OnBeat LLC in the Lifestyle category, specifically targeting Health & Fitness. This app aims to provide the best fitness class cardio experience without the hassle of setting up for days. With OnBeat, users can easily download the app on their iPhone or iPad and start using it right away.

One of the key features of OnBeat is its "bring your own heart rate monitor" platform. Users can utilize their own heart rate monitors, eliminating the need for expensive proprietary ones. The app allows for the simultaneous connection of up to 12 Bluetooth heart rate monitors without additional hardware. For more than 12 monitors, users can purchase an antenna from OnBeat.

OnBeat also offers seamless integration with MINDBODY, a popular gym management software. Users can sync their MINDBODY accounts within the app, saving time by automatically importing class lists. This eliminates the need for manual entry of client information.

Designed for both small and large gyms, OnBeat allows for the display of cardio performance during classes. Users can link their clients' heart rate monitors to the app before starting a class, and the app remembers them for future sessions. It supports most modern Bluetooth heart rate monitors, but FitBits and Apple Watches are currently not supported due to their limited sharing capabilities with third-party apps.

Overall, OnBeat provides a convenient and efficient solution for gyms and fitness classes to track and display heart rate data during workouts. It offers flexibility in heart rate monitor options and seamless integration with MINDBODY for streamlined management.
