Symptom Tracker - BodyFeel

BodyFeel — Spot the patterns in how you feel

BodyFeel is a private daily journal for meals, sleep, energy, mood and the symptoms you'd rather understand. Log in seconds. BodyFeel quietly looks for the patterns connecting them.

What you can track
• Meals — quick-add by name, with categories
• Symptoms — type and severity (1–5)
• Sleep — hours and quality
• Energy — five-step scale, drained to peak
• Activity — type, duration, intensity
• Mood — one-tap check-ins
• Hydration — water intake in ml
• Cycle — period flow and cycle stats (for women)

Tap a quick-add tile, fill what you remember, done. Every optional tracker can be turned off in Settings.

Patterns, not diagnoses
BodyFeel runs a small statistical model on your own data — Welch's t-tests, two-proportion comparisons, and false-discovery-rate control — to surface observations like:
• "On symptom days, sleep may be less."
• "Meals containing tomato may be followed by symptoms within 6 hours."
• "Symptom frequency may be falling over the last week."

Every observation comes with hedged language, the sample size it's based on, and an effect-size label. High-confidence findings only appear when they replicate in both halves of your data.

This is a tool to spot patterns to discuss with your clinician. It is not a diagnostic, and it does not provide medical advice.

Built for clinician conversations
• Tap any logged entry to view its full details.
• Calendar view to step through past days.
• One-tap PDF report (over a date range you choose) you can email or AirDrop to your doctor — includes summary stats, saved insights, and a timeline.

Your data stays on your iPhone: BodyFeel never uploads your logs to our servers. Everything is stored locally on your device. You can export an encrypted backup file at any time, restore it on a new device, or wipe everything in one tap.

Free, with optional Plus
• Free: log up to 5 entries per day across all categories
• BodyFeel Plus ($4.99/month or $34.99/year): unlimited entries and deeper insights

## Important: BodyFeel is intended for informational purposes only and is not a medical device. It does not diagnose, treat, cure, or prevent any disease or condition.
