## What is ReactLog?

You take a supplement every morning. But is it actually doing anything?

You cut out dairy last week. Did it help — or was it something else entirely?

You can't answer these questions with memory. You need data. ReactLog turns your daily habits into clear, actionable intelligence about your body.

How it Works: Log what goes in — supplements, medications, food, caffeine, anything. Then check in with how you feel throughout the day: mood, energy, focus, symptoms. Takes 10 seconds.

Over days and weeks, ReactLog's on-device engine analyzes your data and surfaces the correlations hiding in plain sight. That magnesium you started three weeks ago? It's correlated with 18% better sleep. That protein bar you eat on Tuesdays? Your afternoon brain fog spikes every time.

This isn't guesswork. It's your own biofeedback data, processed privately on your device.

What you Get: 

- Biofeedback OS — A living intelligence layer that monitors your active signals and flags what matters
- Smart Correlations — See exactly how each input connects to how you feel, ranked by strength
- Mood Intelligence — Track psychological states across 5 dimensions with quick check-ins
- Supplement Tracking — Log any supplement, medication, or compound with one tap
- Apple Health Sync — Automatically pulls 15+ biometrics including sleep, HRV, steps, and heart rate
- Insight Engine — 38+ smart signals analyzed continuously as your data grows
- Timeline — Visual history of everything you've logged, searchable and exportable
- Protocols — Build and track structured supplement or wellness routines
- Achievements — Stay motivated with milestones tied to real consistency

Who is this For?

You take supplements and wonder if they actually work. You suspect certain foods are tanking your energy. You're managing a chronic condition and need to identify triggers. Your doctor asked you to keep a symptom journal. You want to optimize how you feel — not guess.
