Grove: Recovery, HRV & Strain

Recovery, HRV & strain — without a $200 wearable or subscription. Grove reads the Apple Watch you already own and gives one daily score: should you push today, or rest?

Grove - Recovery, HRV and Strain Tracker

Turn your Apple Health data into a daily recovery score. Grove reads HRV, sleep, resting heart rate, and workout strain to tell you when to push and when to rest, using only the iPhone and Apple Watch you already own. No chest strap. No subscription required. No streaks to break.

WHY GROVE Most recovery trackers shout numbers at you. Grove gives you a single, glanceable readout of how your body is actually doing, built on the same metrics elite athletes pay hundreds a year to track, surfaced in an interface designed to be calm instead of demanding. Whether you are training for a marathon or recovering from burnout, Grove translates HRV, sleep, and strain into one daily question: should you push today, or rest?

WHAT GROVE TRACKS Recovery Score. A daily readiness reading from HRV, resting heart rate, sleep, and recent strain. HRV. Overnight heart rate variability, the gold standard signal for autonomic balance. Sleep. REM, deep, and core sleep stages with efficiency and consistency trends. Strain. Cardiovascular load from every workout, tracked without judgment. Trends. 7, 14, 30, and 90 day windows so you can see patterns, not just snapshots.

KEY FEATURES Works with Apple Watch Series 4 and later, including Ultra. Apple Watch is optional, since Grove also works with whatever HRV and sleep data is already in your Health app. On device processing. Your raw biometric data never leaves your iPhone. No streaks, no guilt, no aggressive notifications. Just a gentle morning summary so you start the day with one clear signal. Minimal interface designed to be glanceable. 7 day free trial of Grove Plus, then a free tier that includes your daily recovery score forever.

WHO GROVE IS FOR Athletes who want recovery, HRV, and strain insights without buying another wearable. Runners, cyclists, lifters, and CrossFit users tracking training load. Anyone managing burnout, long COVID, or chronic fatigue who needs to track readiness day to day. People searching for an Apple Watch recovery tracker, HRV tracker, or strain tracker that respects their attention. Anyone who tried a subscription wearable and wants the insights without the hardware or the monthly fee.

HOW IT WORKS Install. Sign in with email or Apple, then grant HealthKit access for HRV, sleep, heart rate, and workouts. Wear. Sleep, train, recover. Grove reads your data quietly in the background. Check in. Each morning, your recovery score and a calm summary tell you what your body needs.

PRIVACY Grove processes HealthKit data locally on your iPhone. Your raw HRV and sleep data are never uploaded. Only your computed daily score syncs to a private Grove account so your history is preserved across devices and reinstalls.

GROVE PLUS After a 7 day free trial, your daily recovery score and home view stay free forever. Grove Plus is 30 dollars per year and unlocks unlimited history, deeper metric breakdowns, and long term trend analysis.

Recovery, HRV tracking, sleep tracking, strain, readiness, training load. One calm app, on the iPhone you already have.
