What's in it
Paste text, screenshot your coach's whiteboard, photograph a notebook. The app builds a structured, timed workout — every time.
Every station shows a target zone. Beat Boss tells you when to push, when to hold, and when to back off — in real time.
WHOOP 4.0+, Apple Watch, Garmin chest straps and modern watches, Polar, Wahoo, Coros, Samsung, Pixel. If it broadcasts BLE, we read it.
Max HR, time in zone, station splits, HR graph. Every session gets a post-workout breakdown the second you finish.
Hunter McIntyre's signature sessions plus classic benchmark and interval templates. No empty-app problem on day one.
Drag, resize, and rearrange widgets. Build the dashboard that matches how you train, not the one we decided for you.
Co-founder
“Every serious athlete I know writes their workout on a notepad, then stares at a stopwatch trying to guess if they're working hard enough. Beat Boss replaces the stopwatch with something that actually knows what you're doing.”
— Hunter
Co-founded and 50% owned by Hunter McIntyre and Austen Alexander. Launching together, August 2026.
Questions
You need any heart rate monitor that broadcasts over Bluetooth (BLE). That covers every WHOOP 4.0+, Apple Watch (via Apple Health), modern Garmin watches with broadcast mode, all major chest straps from Polar / Wahoo / Garmin / Coros, Samsung Galaxy Watch, and Pixel Watch. Older Garmin watches that only broadcast ANT+ aren't supported — you'd need a chest strap to use with them.
Launching August 2026
TestFlight beta opens in June. Early email signups get priority access, Hunter's launch-day workout, and founder content along the way.
