PaceGrid vs BeatZone

Make your next run or ride easier to understand. PaceGrid brings GPS recording, routes, heart rate and training history together on iPhone and Apple Watch. RECORD YOUR WORKOUT Follow distance, pace, time and splits. Review your route and elevation afterwards, or record from Apple Watch without carrying your phone. CONNECT YOUR HEART RATE Pair a compatible Bluetooth heart-rate strap from the Record screen. PaceGrid uses fresh strap readings during recording and makes connection problems clear. Supported smart rings add heart-rate, sleep and recovery data. Device features vary by model. SEE THE BIGGER PICTURE Explore training load, heart-rate zones, workout trends and recovery estimates.

BeatZone connects to any Bluetooth heart rate monitor — including WHOOP, Polar, Garmin, and more — and gives you real-time alerts when your heart rate leaves your target zone. Set your low and high thresholds, and BeatZone does the rest. A pulsing heart animation shows your live BPM, color-coded by zone. When your heart rate drifts below or above your targets, you get an instant audio alert. If you stay out of zone, recurring alerts fire at an interval you choose so you never miss it.
