Krasis reads what you're about to eat and tells you whether it will hold you — and what one thing to add if it won't.
Protein · fibre · healthy fat. Three vessels, filling.
No calories. No macros. No logging. You say what you're about to eat, in your own words. Krasis answers in a sentence, and if something's missing it suggests one thing to add — drawn only from the staples you told it you actually keep. It never suggests quinoa to someone who has never owned quinoa.
About two hours later it asks one question — still full? — and one tap answers it. That's the whole loop. Over a few meals it learns which of your plates actually hold you, which is something no calorie count can tell you.
κρᾶσις — the blending of elements in due proportion, from κεράννυμι, to mix. In Hippocratic medicine a good krasis was health and a bad one illness. The same idea applied to a plate: protein, fibre and fat, mixed well enough to hold you.
Krasis is free to use: unlimited checks, the read, the rescue, and a kitchen of up to twenty-five staples. Plus adds your history and the pattern it reveals, unlimited staples and more than one kitchen, check-backs timed to you, widgets and a Watch complication, and saved combos.
Eurozone prices. The App Store shows yours in your own currency, and that is the price that applies.
Krasis works entirely offline, from a table built by merging four openly licensed national food composition databases — BLS 4.0 (Germany), Ciqual 2025 (France), CoFID 2021 (United Kingdom) and USDA SR Legacy (United States) — with hand-curated entries where those four leave gaps, largely Greek foods. Full attribution is in the app, on the About screen, as those licences require.
