Give it a few weeks.

Patterns need data. Two to four weeks of ordinary life does it.

See what repeats.

Intestigator surfaces the correlations, trends, and spikes in your own logs.

What you’ll see

Bloating Yogurt · 9/13 · ~5h

Correlations you can see.

Which foods and drinks tend to show up before a symptom — with how often they co-occur and the typical delay. Your data, nobody else’s.

Spikes and highlights.

When a symptom jumps against your own baseline, you’ll see it — like “Cramping ↑ 4.3× this week.”

Doctor-ready reports.

Export your history as CSV or PDF for your next appointment.

Private by design.

Your logs live on your device and in your iCloud. No accounts, no ads, no selling data.

Patterns, not prescriptions

Intestigator never diagnoses and never gives advice. It shows you your own data — patterns worth a conversation with your doctor, never a substitute for one. You’ll even find that reminder inside the app.
