Cadence reads your sleep, HRV, and resting heart rate every morning at 5:42 AM and rewrites your week. Push when you're recovered. Back off before you break. The plan adapts — you don't have to.
No more rigid training cycles that ignore the fact you slept 4 hours last night. Cadence adjusts every morning at 5:42 AM, before you wake.
Connect Apple Watch, Garmin, Polar, or Whoop. We backfill 90 days of HRV and sleep to set your baseline.
Race date, distance, or just "get stronger." We build a 4–24 week periodized plan tuned to your current fitness.
If your HRV's down 18%, today's threshold becomes easy aerobic. If you're sharp, we push harder. You just train.
Most plans pretend you sleep 8 hours and never travel. Cadence builds in base / build / peak / taper, then quietly shifts intensity day-by-day as your body changes.

I'd run four marathons. Three on rigid PDF plans from coaches who'd never seen my HRV. Every block ended in a stress fracture or a chest cold or a quiet conversation with my husband about whether I was OK.
Cadence pulled my data the first night. By day 3 it was telling me to skip the tempo because my HRV had cratered. I trusted it. Fourteen weeks later I ran 2:58:42 in Berlin — and crossed the line feeling like I could've kept going.

Everything in Plus, plus a USAT- or NSCA-certified human coach you can text.
Apple Watch (Series 6+, Ultra), Garmin (Forerunner 245+, Fenix 6+, Epix, Edge cycling), Polar (Vantage V2/V3, H10 strap), Whoop 4.0, and Coros (Pace 3, Apex 2). Workouts push to the watch automatically. We don't support Fitbit because the HRV API is locked. Suunto is on the roadmap for Q3.
We track rolling 7-day morning HRV against your 60-day baseline (rMSSD, log-transformed to handle skew). A 10%+ drop for 2+ days triggers an auto-deload. Your Pro coach sees the same chart and overrides the algorithm 12–18% of the time based on context the data can't see (work stress, travel, illness). The model is open — we publish the methodology and won't pretend it's magic.
Yes, but you'll get ~60% of the value. Without HRV we fall back on subjective wellness check-ins (sleep, soreness, motivation on a 1–5 scale) which still produce a reasonable adaptive plan but with less precision. We recommend pairing with a Whoop strap ($30/mo) or a sub-$300 Garmin if you're serious.
No. Monthly plans cancel inside the app in two taps and you keep access through the billing period. Annual plans are pro-rated and refunded for unused months if you cancel within the first 60 days. Pro plan (with a human coach) requires 14 days' notice to give your coach a clean wrap-up. We don't fight you on it.
Every Pro coach holds at least one of USAT Level 1+ (triathlon), USAC Level 1+ (cycling), NSCA-CSCS (strength), RRCA (running), or equivalent. ~38% are former pros or NCAA Division 1 coaches. We list each coach's certs, athlete count, and recent results publicly — and you can read your coach's actual plan before committing.
HRV is intimate data — it tells a story about your stress, your sleep, your moods. We store it under tight controls, sell it to no one, and let you delete it in one click.
Pair your watch, set a goal, and wake up tomorrow to a plan that knows you. No card on file. Cancel from inside the app.
