Your health apps track pieces. 4sight shows you the picture. 4sight is the AI-powered wellness platform that unifies your sleep, fitness, nutrition, and mental wellness data into one intelligent dashboard — revealing cross-pillar correlations that single-purpose trackers can never show you. WHY YOUR CURRENT APPS AREN'T ENOUGH Your calorie tracker can't tell you why you're not losing weight. Your sleep tracker can't explain what's draining your recovery. Your fitness app doesn't know your stress levels are sabotaging your gains. Each app sees one piece. 4sight sees the whole story. FOUR PILLARS. ONE SCORE. ZERO BLIND SPOTS. MOVE — Steps, calories, distance, heart rate, HRV, VO2 Max, blood oxygen, 24+ workout types with sets/reps/weight tracking, body composition, blood work labs with trend tracking across 30+ biomarkers. FUEL — Calories and macros from your favorite trackers, hydration logging, caffeine clearance timer, intermittent fasting with eating window tracking, medication and supplement adherence monitoring, and a 400M+ food database with barcode scanning. REST — Sleep duration, efficiency, and stage analysis (deep, light, REM), sleep and dream journaling, bedtime consistency tracking, HRV-based recovery scores, and 11 relaxation activities including breathing exercises, meditation, cold plunge, and sauna sessions. RISE — Mood, energy, and stress tracking with a visual mood calendar, gratitude and diary journaling with sentiment analysis, Pomodoro timer, deep work sessions, flow state tracking, guided meditation with immersive mode, and visualization exercises. GALEN AI — YOUR PERSONAL HEALTH ASSISTANT Ask your health data anything in plain language. "Why am I always tired on Wednesdays?" "How does caffeine affect my sleep?" "What do my best days look like?" Galen analyzes your data across all four pillars and gives you real answers — not generic advice. THE COMMAND CENTER Your composite wellness score (0-100) shows your overall balance across all four pillars at a glance. The Time Machine lets you revisit any day and see an AI-generated narrative of how your pillars interconnected. Spot patterns you'd never find on your own. CONNECT EVERYTHING YOU ALREADY USE Fitbit, Apple Watch, Garmin, Whoop, Oura Ring, RingConn, Renpho, Strava, LoseIt, MyFitnessPal, Google Fit, Headspace, Calm, and more through Health Connect and HealthKit.

Your body has an age your birthday doesn't show. FixMyAge helps you measure it, understand it, and reverse it. Standard healthcare waits until something breaks. We measure how fast you're actually aging — then give you a protocol built from your own lab results, and the tools to follow it every day. WHAT YOU CAN DO IN THE APP Overview See your biological age, aging rate, and key health metrics at a glance. Track your trajectory over time and know exactly where you stand. Protocol Following Access your personalized longevity protocol — built from your lab results and tagged with the evidence behind every recommendation. Supplements, nutrition guidance, training, and recovery procedures, all in one structured plan. Supplements Management Log your daily intake, track compliance, and stay on top of your stack. Know what you're taking, when, and why — with dosing and timing built into your protocol. THE SCIENCE Every protocol links to published research from journals including Nature Aging, Cell Metabolism, JAMA, and The Lancet. Recommendations are tiered by evidence quality so you always know what's well-proven versus emerging. IMPORTANT FixMyAge is an AI-powered health advisory and tracking service, not a medical practice. Protocols are generated by AI based on published research and your personal data. For diagnosis, prescriptions, or treatment of medical conditions, consult a licensed physician.

Verdict
The clearest difference is in-app purchases: FixMyAge at none against 4Sight Fit's 2. 4Sight Fit's advantage is update cadence (every 11 days vs every 5 weeks) and iOS requirement (15.1 vs 17.6). On price, ads and device support there is nothing between them.
