As hybrid training takes off, Hybrd has emerged from an invitation-only private beta to give athletes a dedicated place to track strength and cardio
Hybrd, a performance-tracking app designed for endurance and strength athletes, has launched publicly on the iOS App Store after six months in invitation-only beta.
Built by a team of former Whoop staffers, national rowers, triathletes and ultramarathoners, Hybrd is unifying fitness data, such as cardio, strength and wearable metrics, solving what its creators call a major pain point: the lack of a unified platform for hybrid athletes.
The app drops at a time when hybrid athletics is booming. Earlier this month, the VTLZR Hybrid Athlete Retreat held its second festival in New York’s Catskill Mountains, drawing everyone from hybrid fitness enthusiasts to seasoned pros. As Hybrd notes, interest in “hybrid athletics” has grown significantly, with search traffic tripling in the past three years and growing tenfold over the last decade.
According to the company, early users of Hybrd include Olympic medalists, professional athletes, national champions, Navy SEALs, Green Berets, Ironman Kona finishers and Hyrox winners.

Hybrd tackles the fragmentation by integrating with popular fitness tools and using AI to streamline data logging across disciplines, delivering what the company says is a complete, personalized view of how an athlete’s total training load is impacting performance.
A demo of the app is available here.
In the spirit of community and a shared love of hybrid athletics, Hybrd also offers free fitness groups access in Boston and San Francisco, featuring weekly workouts and social events.
