Nibble used to be called Macra

Same app, same account, same data. If you installed Macra, updating from the App Store gives you Nibble; nothing needs to be re-entered and your subscription carries over.

Logging meals

  • Photo — tap the camera, snap your plate, and Nibble's AI identifies each item and fills in calories, protein, carbs and fat. You can edit any item or portion before saving.
  • Voice — hold the mic and say what you ate ("two eggs, toast with butter, a latte").
  • Barcode — scan packaged food for exact label nutrition.
  • Search — look up a food and enter the amount by hand.

AI estimates are estimates. For packaged food the barcode is always more accurate than a photo, and you can correct any entry after the fact.

Subscriptions and billing

  • Plans: Nibble Premium is billed through Apple as a monthly or annual subscription. Prices are shown in the app before you buy.
  • Manage or cancel: subscriptions are handled by Apple, not by us. Open apps.apple.com/account/subscriptions (or iPhone Settings → your name → Subscriptions). Cancelling stops the next renewal; you keep access until the end of the current period.
  • Refunds: Apple processes all refunds. Request one at reportaproblem.apple.com. We can't issue refunds directly, but email us if you're stuck and we'll help.
  • Restore purchases: new phone, or Premium not showing? open the Premium screen in the app and tap Restore purchases at the bottom, while signed in to the same Apple ID you bought with.

Apple Health

Nibble can write nutrition and weight to Apple Health and read weight back. Turn it on in Settings → Apple Health; you choose exactly which data types to share. If sync stops, check iPhone Settings → Health → Data Access & Devices → Nibble.

Your data

  • Export: email us and we'll send your log as a file.
  • Delete your account and data: use Settings → Delete account in the app, or email us from the address on your account and we'll delete everything within 30 days. This does not cancel an Apple subscription — do that separately (see above).
  • Privacy: we don't sell your data. Full details in the Privacy Policy and Terms of Service.

Something's broken

First try updating Nibble from the App Store and restarting your phone. If it still misbehaves, email us with your iPhone model, iOS version, and what you were doing when it happened. Crash reports help enormously.
