Revivex is your daily health hub. It connects the trackers you already wear, reads the signals they produce, and turns them into one clear answer each morning: how ready are you today — and what should you do about it? ONE READINESS SCORE Recovery, sleep, and strain from your connected sources are distilled into a single Readiness score with plain-language guidance. No more jumping between apps to piece together how you're doing. CONNECT WHAT YOU ALREADY WEAR • WHOOP — recovery, sleep performance, strain, and workouts • Oura — sleep and recovery signals • Apple Health — steps, heart rate, HRV, workouts, VO2 max, and more Data syncs automatically and every screen shows exactly which source it came from. TRAIN WITH INTENTION A daily Train score calibrated to your recovery tells you when to push and when to protect. Get suggested sessions matched to the day — from Zone 2 runs to mobility flows — and generate a workout that fits your equipment, goals, and available time. SLEEP & RESTORE See sleep achieved vs. what you actually need, track sleep debt across the week, and get evidence-informed wind-down guidance for the hours between training. NUTRITION WITHOUT THE SPREADSHEET Log meals in seconds — snap a photo, scan a barcode, or search a database of everyday foods. Revivex scores how closely your day tracks your calorie and protein targets, derived from your goals. HEALTHGPT — ASK YOUR DATA ANYTHING Your AI health coach reads your last seven days of connected data and answers with structured, signal-driven guidance. "How did I sleep this week?" "Should I train hard today?" Ask, and get an answer grounded in your own numbers. KNOW YOUR ENVIRONMENT Air quality, UV, pollen, and weather for wherever you are — with practical calls like whether it's a good day to train outside. SUPPLEMENTS, ORGANIZED Build your stack, check it off each day, and see research-informed suggestions matched to your goals. YOUR DATA, YOUR CALL You choose what to connect, and you can disconnect any source at any time. Revivex provides general wellness information and is not a medical device.
