Know exactly what to do today for a longer, healthier life. synqology turns the Apple Watch you already own into a longevity platform. No extra hardware. No monthly strap. At its core is the Vitality Index: a single 0–100 healthspan score built from your sleep, HRV, resting heart rate, VO2 max, activity, and strength over a rolling 28 days. It cuts through daily noise to show your true long-term health trend—and the one thing to improve next. VITALITY LOOPS Three rings a day—Move, Train, Sleep—sized to your own data every morning, not a generic goal. Close two of three and the day counts toward your streak. One repair a week keeps a slip from breaking it. A PLAN YOU SHAPE YOURSELF Slide your weekly steps, cardio, and strength and watch your 30-day Vitality Index projection move with them. Save it, and that becomes your plan—your rings, your brief, and your Watch follow it. MORNING & EVENING BRIEF Every morning, synqIQ tells you where you stand and what matters today. Every evening: the day's numbers and which loop you can still close before bed. ON YOUR WRIST AND HOME SCREEN • Apple Watch app: your rings and streak on the watch face, and a buzz on your wrist when a loop closed—without opening your phone. • Home Screen widgets: pick the ring or the streak. Free for everyone. Apple Watch delivers workouts instantly, but step and exercise-minute totals arrive in batches, so a Move close can land a few minutes after the fact. KEY FEATURES • Vitality Index: A 0–100 healthspan score from a rolling 28-day baseline of your physiology and behavior—your true progress, not today's fluctuations. • Daily Readiness: A recovery score each morning from your HRV and resting heart rate versus your personal baseline. Know when to push and when to rest. • Sleep Score & Sleep Debt: Go beyond duration—combine efficiency and stages to understand your sleep quality and manage the debt you're carrying. • Momentum: See your consistency toward the daily signals that build a stronger baseline. • synqIQ AI Chat: Ask "Why is my recovery low today?" and get clear, evidence-informed answers grounded in your real Apple Watch data. FREE PEPTIDE, SUPPLEMENT & HABIT TRACKING Log peptides, supplements, medications, and practices in seconds—completely free. • Peptides & supplements: Track your stack and dosing over time. • Practices & habits: Meditation, cold exposure, breathwork, yoga, HIIT, and more. • Custom metrics: Mood, pain, hydration, blood pressure—anything you care about. APPLE WATCH + OURA Seamlessly sync steps, heart rate, HRV, workouts, mindfulness, and sleep from Apple Watch. Prefer Oura for sleep? Connect it for sleep tracking (recovery scores use Apple Watch HRV). PRICING synqology is free to start—no trial required. Your core longevity tools stay free forever: the Vitality Index, daily Readiness, Sleep Score, Sleep Debt, Momentum, Vitality Loops with your streak, the morning and evening brief, Home Screen widgets, the Apple Watch app, food and water logging with the full nutrient panel, peptide/supplement/habit logging, your first two Weekly Longevity Reports, and a monthly allowance of synqIQ AI chat and AI food scans.
