Snapkin

Snapkin is a calorie and protein tracker that works from a photograph of a meal instead of a barcode scan or food database search. It is built for people who have quit other calorie trackers because logging felt like too much work, letting them photograph a plate and get calories and protein without weighing ingredients.

After a photo is taken, Snapkin names what is on the plate, works out portion sizes from the plate and any knife or fork in frame, and counts cooking fat and sauce most trackers miss. When one detail would change the estimate materially, it asks a single question and shows how much the answer matters, then adds the calories and protein to the day without anything to confirm or save.

Snapkin remembers past meals so a repeated dish can be logged again in a few taps with no new photo, and it learns habits over weeks so familiar meals need fewer questions. It reads weight from Apple Health or Health Connect, suggests a calorie target that adapts to results after a month, works in ten languages, and can suggest meal ideas from a photo of a fridge, cupboard, or restaurant menu.

Snapkin is available on the App Store and Google Play, with widgets for the home screen and iPhone Lock Screen and dials on Apple Watch and Wear OS. It is one subscription at €9.99 a month or a discounted yearly launch price, with a three-day free trial and no card required; there is no free version. On a typical meal it was tested within 17% of a kitchen scale, and it offline-queues photos with no signal.
