Your smartwatch already has the data. Threshld figures out what it means.

One daily Recovery Score, 0 to 100, built from your heart rate variability, resting heart rate, and sleep quality. Calibrated to your own baseline and refreshed every morning, so the number means something for you, not for an average.

CALIBRATED TO YOU
Amazfit, Garmin, Samsung Galaxy Watch, Pixel Watch and other wearables write their biometrics to Android Health Connect. Threshld reads those numbers and applies one consistent algorithm, tuned to you over your first two weeks. A score of 65 means something different for a cyclist in peak training than for someone recovering from illness. Threshld accounts for that.

NO BLACK BOX
Tap the score to see exactly what each factor contributed. Heart rate variability shows how regulated your nervous system is after sleep. Resting heart rate is your overnight low. Sleep quality combines duration, efficiency, and stage distribution. Every input is shown on its own, so you can see what drove today's number.

SLEEP, IN FULL
The Sleep tab charts your night as a timeline: light, deep, and REM stages from first sleep to wake. Duration, efficiency, and a weekly trend show whether last night was an outlier or a pattern. Real sleep tracking, not a "you slept 7 hours" counter.

TRAIN WITH YOUR RECOVERY
Workout history with duration and heart rate. Daily steps, active calories, and weekly effort. Read your training load and Recovery Score together: high strain followed by a low score means your body is responding normally. Know when to push and when to back off.

YOUR DATA
Your raw health data stays on your phone. Threshld reads your HRV, heart rate, and sleep from Android Health Connect, a local layer on your device, and those detailed metrics are never uploaded. A free account, by email or Google sign-in, backs up your profile and your daily scores so you keep your history if you change phones. We never sell your data, and Threshld shows no ads.

WORKS WITH YOUR WATCH
Compatible with any wearable that writes to Android Health Connect: Amazfit, Garmin, Samsung Galaxy Watch, Pixel Watch, Fossil, Polar, Withings, OnePlus Watch, and more.

If you have looked for a recovery score outside Garmin's ecosystem, a Body Battery or Oura alternative, or WHOOP-style readiness insight without the dedicated wristband, Threshld covers all of it.
