What people use Luca for

Same app, different reasons. Pick the one that sounds like you.

Calories without typing

Take a photo of your meal and get an editable estimate of calories and macros in seconds. For people who gave up on logging because of the typing.

Tracking protein

See an estimate of the protein in each meal and how the day adds up against your protein target, from a photo, your voice, text or a barcode.

Packaged food by barcode

Scan the barcode on packaged food and log its label nutrition in seconds. Unlimited on Luca's free plan, with label reading as a fallback.

Eating out

Restaurant meals rarely come with a label. Photograph the plate for a quick estimate of calories and macros, then adjust for what you can't see.

Logging with a friend

Add a friend by a 4-character code, share streaks and challenges, and keep meals private. Friends see streaks and badges, never calories or photos.

Macros for beginners

New to macros? Luca shows calories, protein, carbs and fat for every meal from a photo, so you can learn what is on your plate before chasing numbers.
