Features
Simple to log. Hard to get wrong.
Search, pick a serving, log.
Typo-tolerant search over a verified catalog. Servings in grams, cups, or the real menu item.
Provenance on every food
Official, reviewed, or estimated — always labeled. Restaurant data is imported from approved sources and re-checked.
Recipes with real math
Per-serving nutrition from snapshotted ingredients. Publish, copy, and star what works.
Never lose a log
Offline drafts retry on their own. Every write is idempotent, so a flaky connection can never double-log.
Private by default
Your diary is yours. Export everything as JSON or delete your account in two taps.
iPhone, Android, web
One app, native on iOS and Android, the same diary everywhere.
For agents
Built for agents first.
The same services behind the app are exposed as a remote MCP server. Your assistant signs in with OAuth 2.1 + PKCE, you approve the scopes once, and it logs what you ate for you.

FAQ
Questions, answered.
Is Calorie Cub really free?
Yes. Logging, the food catalog, restaurant menus, recipes, and export are free with no time limit. Pro adds logging by chat from AI assistants and a larger photo and voice allowance.
How does the Pro trial work?
The yearly plan starts with 3 free days. Cancel before the trial ends and you pay nothing. If you cancel later, Pro stays on until the end of the period you paid for.
How do I cancel?
On iPhone, in your App Store subscriptions. On Android, in your Google Play subscriptions. On the web, from Manage subscription in Settings. Apple, Google or Stripe handles payment; we never see your card number.
Where does the nutrition data come from?
The USDA, restaurants’ own published nutrition guides, and foods people add. Every food is labeled official, reviewed, or estimated, so you know what you are logging.
Do you sell my data?
No. We don’t sell data, show ads, or use your diary for advertising. Export everything as JSON or delete your account anytime in Settings.
Can I bring my MyFitnessPal history?
Yes, on the web. Unzip your MyFitnessPal export and choose its Nutrition-Summary and Measurement-Summary files in Settings. Each meal comes in with its calories and macros, and your weigh-ins come too. Individual foods don’t carry over, because the export doesn’t list them.
Which assistants can log for me?
Any app that supports remote MCP servers, including ChatGPT, Muse and Claude, where Calorie Cub is a community connector in the Connectors Directory. You approve each app once, and you can disconnect it from Settings at any time.
