⚡ How It Works
Step 1
Type what you ate
In plain words, like "two slices of sourdough" or "a turkey sandwich on wheat". Brand and restaurant foods work too.
Step 2
CarpeCarb looks it up
Brand and chain foods are matched in USDA FoodData Central first. Everything else is checked against the web and USDA survey data.
Step 3
It joins your day
Carbs, protein, fat, fiber, and calories go into today's log under the right meal, labelled USDA, Web, or Manual.
Step 4
Track your day
Watch the progress bar fill toward your daily carb goal, with a total for each meal. Your day resets at the hour you choose.
No guesses: if CarpeCarb can't find a reliable carb count, it says so and asks you to enter it from the label. It never fills in a made-up 0 g.
🆓 Everything Is Free
Every feature in CarpeCarb is available to all users — no paywall, no locked screens.

🔒 Privacy & Security
- No account required — CarpeCarb uses anonymous authentication. We never know who you are.
- No ads, no data selling — your food log stays on your device and in your own iCloud.
- Apple Health data stays yours — it is never sent to our servers.
- Lookups stay anonymous — they go through our own server, tied only to an anonymous ID, and we don't keep your searches.
- Keys stay on the server — the keys for our lookup services live in Google Cloud Secret Manager, never in the app.
- Rate limited — every request is checked against a per-user limit to prevent abuse.
