An AI coach that listens
and adapts to where you're at.
Pairform connects your workouts, sleep, HRV, and recovery into one place, then coaches you from it. Tell it how you're feeling, what you're training for, what's going on this week — it listens, reads your data, and adapts day by day.
Tell it what's going on
Work is crushing you this week. Your knee is a little cranky. You've got a race in six weeks and a bachelor party in three. Pairform's AI coach takes it in — the plans, the context, the mood — and folds it into what it recommends.
Grounded in your real data
Every recommendation is anchored to what your body actually did. Strava workouts, sleep, HRV, recovery, training load — all live, all synced. So the coaching you get reflects you today, not a generic plan written months ago.
Start freeEverything your coach needs to know you
Your workouts, recovery, and readiness — all in one place, feeding a coach that adapts with you.
Daily Readiness Score
A 0–100 score from training stress balance, sleep, HRV, recovery, and injury status. Tells you whether today's hard workout is actually a good idea.
Injury Risk Monitoring
Acute:chronic workload ratio (ACWR) flags when you're ramping into the injury zone before you blow up your block. The thing your training app should be tracking.
Training Load
Automatic CTL, ATL, and TSB so you know when you're fresh, fatigued, or ready to race — without having to spreadsheet it yourself.
