Sliptrack builds your daily recovery score from phone data and a 60-second check-in — sleep quality, perceived effort, soreness. No wristband, no subscription hardware, no $30/month. Built for runners, cyclists, and triathletes.
After each run, ride, or session, rate how hard you pushed. We convert it to a strain score that compounds across your training week — no heart-rate monitor required.
A 20-second check-in: how long, how well, did you wake up rested. No sleep tracker required — self-assessment is surprisingly accurate input for recovery math.
We compute your recovery percentage and give you a plain recommendation: push hard, train easy, or take the day off. No jargon, no ambiguity.
Training 40+ miles a week needs structure. Know when rest is the actual workout — before your body makes the decision for you on mile 18.
Track cumulative training load without a power meter or a coach. Understand when you're overreaching before the legs go flat mid-week.
You already have a bike computer, a GPS watch, and a heart-rate strap. You don't need another device — you need the insight those devices can't give you.
You've looked at WHOOP. $30/month felt like a lot. It is a lot. Try the model before you buy into the hardware — no wristband required to test the concept.
We're onboarding the first 500 users now. Free during beta — no credit card, no wristband, no catch.
