Vayl PRO

Reveal your biology. Vayl is a private tracking instrument for serious athletes — the people who already track macros for months, measure body composition, and read their own labs. It consolidates what your body signals into one obsidian instrument. BODY — sleep, HRV, blood pressure, VO2max, weight, body composition and skinfold trends. Your biology, read like a terminal. TRAINING — strength sessions with tonnage and muscle distribution, cardio zones, mobility. Every loaded rep counted. NUTRITION — macros to the gram, weekly adherence, meal plans, hydration. ALCHEMY — plan and log your medications and therapies on a schedule, and model them over time. A model of your schedule. LABS & RECORDS — bloodwork, measurements, symptoms and recovery, tracked over time. Apple Health sync. Offline-first: logging works without signal and syncs to your private account. Export or delete your account anytime. Vayl reveals; it never prescribes. Zero medical advice. Adults 18+. SUBSCRIPTION Vayl Pro is a subscription. New subscribers get the first month free, then $12.99 per month or $99.99 per year. With the free month, payment is charged to your Apple Account when it ends; without it, at confirmation of purchase. The subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Manage or cancel it any time in your Apple Account settings. The same subscription opens the web terminal at vayl.pro. Terms of Use: https://vayl.pro/terms Privacy Policy: https://vayl.pro/privacy
