Shall we start? 
Meet Mampf
Your friendly hamster companion. Mampf's mood depends only on whether you check in - never on what or how much you eat. Keep it up and he goes wild with joy; stay away a while and he gets a little sad. He never judges your food - and Quiet Mode calms him down completely.

Mampf has many sides
Sometimes cool, sometimes head chef, sometimes totally over the top - in the widget, on the watch and in the app, Mampf likes to go wild. Never because of your food. Just because you showed up.

Privacy
Your data? It's yours.
Mampf is curious about you - not your data. No account, no tracking, no data selling.
- Your diary stays on your device - optionally in your own iCloud. We never see it.
- No account, no login. Just start.
- Photo scan: the image is processed briefly, never stored - location data removed first.
- No ads, no trackers, no data brokers.
"Other apps feast on your data. I'd rather snack on sunflower seeds." - Mampf
Barcode scan
Scan a product, pick a portion, done. Data from Open Food Facts, cached locally - the second scan works offline too.
AI photo scan
Photo of your plate, AI estimates calories - as a smart first draft. Always editable, with an honest confidence hint. Never sold as magic truth.
Frequently asked questions
Is it really free?
Yes. No subscription, no premium, no in-app purchases, no ads. Satt doesn't fund itself through your data.
How accurate is the photo scan?
Honest answer: photo estimates are typically 15-25% off, more or less depending on the dish. That's why every result is editable and shows a confidence. Use it as a quick first draft, not an exact measurement.
What data do you collect?
In the app: none. Your diary stays on your device (and optionally in your own iCloud). Only for the photo scan is the image briefly sent to our service and to Anthropic, processed there and not stored. Location data (EXIF/GPS) is removed beforehand.
