LucaMyFitnessPal and Luca both count calories, but they start from opposite ends. MyFitnessPal is built around searching a very large food database. Luca is built around pointing an iPhone at a plate and correcting an estimate.
Where MyFitnessPal is the better choice
MyFitnessPal does a lot that Luca does not, and it is fair to say so first.
- A huge searchable database. Its App Store listing says you can log from 20.5M+ foods, including restaurant dishes. Luca makes no claim about a database size.
- More platforms. MyFitnessPal has iOS and Android apps and a website that sync through one login. Luca is iPhone only.
- More than food. The listing describes recipes, a meal planner, a water tracker, workout and step logging and an intermittent fasting tracker. Luca tracks calories and macros and nothing else.
- Devices. MyFitnessPal says more than 35 apps and devices connect to it, including Apple Watch, Fitbit and Garmin.
- Community. There are public forums and diary sharing with friends.
- Guidance. The listing describes an AI nutrition coach built into the app.
If you already log by searching and weighing, or you need Android or a browser, MyFitnessPal is the better fit.
Where Luca is different
- Photo first, with one free scan a day. Photograph a meal in a square frame and Luca returns an estimate of calories, protein, carbs and fat with an item list. Every item and number can be edited. In MyFitnessPal, Meal Scan, Barcode Scan and Voice Log are Premium features. See how Luca works.
- Four ways to log. Photo, voice, a typed description or a barcode. Barcode and manual entry are unlimited on the free plan.
- No account. There is no sign-up and no email. The app uses an anonymous identifier.
- Where the photo goes. Photos are sent for analysis to servers the developer runs, not to a third-party AI provider, and are not stored on the server. Meals live on the device, and in your iCloud if you have it enabled. More on the privacy page.
- Friends see less. Friends see your display name, avatar, streak, whether you logged today, whether you met your goal and your badges. They never see calories, macros, meals or photos. In MyFitnessPal you choose whether friends can open your diary.
- Price. Luca Pro is $6.99 weekly, $9.99 monthly or $49.99 yearly in the US. Details are on the pricing page.
If typing is the part of tracking you skip, read counting calories without typing.
What neither can promise
A number from a photo is an estimate in any app. MyFitnessPal’s own help page says Meal Scan “gives you a starting point, not a final answer”, and the same is true of Luca: check the items and portions and adjust them. Database entries, in any app, can also be incomplete or out of date.
Neither app is a medical device, and nothing here is medical or dietary advice. Calorie and macro targets are general information, not a plan made for you.
