PERFORM – RECOVERY, STRAIN & SLEEP FOR APPLE WATCH
Unlock WHOOP-style insights using the watch you already wear.
WHY PERFORM?
If you have searched for “Whoop alternative”, “Apple Watch Ultra recovery”, or “HRV readiness tracker”, you just found it. Perform converts your Apple Health data into three simple numbers every athlete cares about:
- RECOVERY SCORE – Morning readiness from HRV, resting HR, respiratory rate and last-night sleep
- STRAIN SCORE – Total cardiovascular load from time spent in elevated heart-rate zones (70-100 percent HRmax)
- SLEEP SCORE – Quality, depth and consistency from REM, Deep and Core stages
No extra straps, subscriptions or clutter – just Recovery, Strain and Sleep on a single page.
KEY FEATURES
- Apple Watch Ultra and Series 4-9 support
- WHOOP-style readiness zones (green / yellow / red)
- Advanced sleep tracking with REM, Deep, Core, disturbances and consistency
- Personalized HR zones and training load for runners, cyclists, CrossFit, HIIT and triathletes
- All data processed on-device via Apple Health and HealthKit – nothing leaves your iPhone
- Actionable notifications: “Good morning! Your Recovery is 86. Time for a tempo run.”
- Zero setup: grant Health access once – Perform syncs automatically in the background
WHO IT IS FOR
- Athletes looking for a WHOOP replacement on Apple Watch
- Users focused on HRV, sleep tracking, readiness, recovery and training load
- Owners of Apple Watch Ultra or Series devices who want deeper performance insights
- Anyone who values a clean, minimalist app that surfaces only the data that matters
