Your morning HRV rewrites today's session.
Veylan is an adaptive coaching app for intermediate-to-advanced lifters with an Apple Watch. Every morning your recovery signals — HRV, sleep stages, resting heart rate, training load — feed a validated algorithm that decides whether today's session runs as written, gets modified, or shifts intensity. The AI brief explains the call in 80 words, citing the specific signal that drove it.
WHY VEYLAN IS DIFFERENT
Other AI fitness apps prompt a language model with your raw data and hope. The result: different answers to the same data, hallucinations, and "you should take it easy today" with no specifics. Veylan doesn't work that way.
The recovery score, fatigue type, and modification level are calculated by a deterministic algorithm — the same input gives the same output, every time. The AI's only job is to write the explanation in plain English. Read 30 daily briefs in a row and they will be consistent, specific, and never vague about what changed in which set on which lift.
That's the moat: deterministic core, narrated output.
WHAT YOU GET, EVERY MORNING
— A daily brief that cites your HRV, sleep, and recent training load, and tells you exactly what changed in today's session.
— A recovery score broken down into the four signals that built it (so you can argue with it).
— Your workout, opened with the modification already applied — no "should I cut this set?" math at the squat rack.
WHAT YOU GET, OVER TIME
— Pattern detection: by week 4 the algorithm starts naming your weekly rhythms (HRV-low Mondays after long runs, PR-friendly Wednesdays).
— Adherence-aware coaching: the brief learns whether you actually follow modifications, and adjusts framing.
— Weekly summaries that cite your specific data points, not generic encouragement.
BUILT FOR
Lifters with 6+ months consistent training history who know the difference between RPE 7 and RPE 9, train 3–6 days/week with a hypertrophy or strength bias, and own an Apple Watch.
Not built for: day-one beginners, casual gym-goers, or athletes without an Apple Watch (manual-only path lands in a later update).

PRIVACY
HealthKit data is used exclusively for your recovery score and your coaching brief — never used to train AI models, never shared, never used for advertising (per App Store Review Guideline 27.9). The AI brief generation runs server-side via encrypted edge functions; the prompt sees aggregated values from your last 14 days, not raw heart-rate streams.

Your recovery score, from day one.
Veylan now imports 60 days of Apple Health history when you first connect, so you get a real recovery score and fatigue read immediately instead of waiting two weeks for a baseline to build.
A sharper recovery engine — improved HRV and sleep signal handling, with clearer confidence when your data is still thin.
Morning brief notifications — your daily score and today's adjustment, delivered before you train.
Per-set rest timer — auto-starts when you complete a set, survives screen lock and backgrounding, with adjustable durations.
Faster loads across home, training and progress.
