ReactLog

See What's Actually Working

Free · In‑App Purchases

Do your supplements actually work? Is that new food making you feel worse? ReactLog answers these questions by connecting what you put in your body with how you actually feel. ReactLog is not a medical device and does not provide medical advice, diagnosis, or treatment. Always consult your healthcare provider before making changes to your routine. Log your inputs (supplements, medications, food, anything) then check in with your mood and symptoms throughout the day. The more often you log how you feel, the more data ReactLog has to work with. Over days and weeks, the app surfaces patterns you'd never spot on your own. WHAT REACTLOG DOES: • Tracks what you take: supplements, medications, food, and more • Logs how you feel: mood, energy, symptoms in quick 10-second check-ins • Connects the dots: surfaces correlations between inputs and outcomes • Syncs with Apple Health: pulls 15+ biometrics automatically • Keeps your data private: everything stays on your device WHO IT'S FOR: • You take supplements and wonder if they're actually doing anything • You suspect a food is causing brain fog, gut issues, or inflammation • You're managing a chronic condition and need to track triggers • You want to understand your energy, mood, and sleep patterns • Your doctor asked you to keep a symptom journal (but notebooks are chaos) HOW IT WORKS: 1. Log what you take: tap to add supplements, meds, or food (takes seconds) 2. Check in with how you feel: rate your mood, energy, and symptoms throughout the day 3. See your patterns: ReactLog analyzes your data and shows you what's connected The key is frequency. A single mood check-in per day is good. Three or four is where the magic happens. The more data points you give ReactLog, the faster it finds the signal in the noise. PRICING: Free to download. Full access for $2.99/month. Cancel anytime. Your data is yours. Export it, share it with your doctor, or delete it completely. We don't sell your information. Ever. Questions?
