What Bauchgefühl does
A diary that thinks along.
Log what you eat. Note how you feel. And finally understand where the connection lies.
Optional AI ingredients
With your own OpenRouter key, the app reads ingredients from a photo or dish name. Off by default — you decide if and when.
Open Food Facts
Search products and barcodes for free — no key, no account — thanks to the open food database.
Link your symptoms
Record your own symptoms with a severity level and link them to meals via multi-select — changeable any time.
Spot the triggers
The correlation engine finds likely triggers and shows a lift factor — e.g. “glutamate + fat: 2.6× more likely to cause symptoms”.
Export for your doctor
Every meal in a date range plus a summary, top ingredients and symptoms as PDF or CSV — perfect for a doctor's appointment.
Logging
Captured in seconds — your way.
One tap on “Add meal” and you choose the fastest route.
- Photo of the plate — a picture beats typing.
- Scan a barcode for packaged products.
- Enter manually when you know exactly what it was.
Ingredients
Suggestions you always review.
Whether from AI, Open Food Facts or by hand: ingredients are always suggestions. You confirm, correct or add — nothing is taken over without your say.
- Ingredients as chips — remove one with a tap.
- Transparent: you're shown where a suggestion came from.
- Time freely adjustable, note optional.
Insights
From a diary to a lightbulb moment.
The more you log, the clearer the picture. Bauchgefühl crunches the numbers in the background and shows which ingredients and combinations coincide with symptoms unusually often.
- Likely triggers with a lift factor.
- Charts for reactions, symptoms, severity and tags.
- How well each property is backed by data, at a glance.
Privacy
Your meals are yours. Full stop.
Bauchgefühl is built as a private tool. There are no third-party servers your entries land on. Everything stays local on your device — and, if you want, synced through your own private Apple iCloud.
Local & in your iCloud
Your data lives on the device and — only if you wish — in your private iCloud. You can turn sync off at any time.
No tracking, no ads
No analytics tools, no ads, no selling of your data. The app makes no money off you.
AI only with your key
AI detection is off by default. Only once you add your own OpenRouter key is a photo or text sent there.
No account needed
No sign-up anywhere. Install the app, get going — done.
Trust your gut.
The app is coming to the App Store soon. Until then, you can already see exactly how it all works.
Not a medical app. Bauchgefühl is a personal self-observation diary and is no substitute for medical advice, diagnosis or treatment.
