Snapkin
Estimates a meal's calories and protein from one photo — no scale or barcode scanning needed.
Snapkin estimates a meal's calories and protein from a single photo, using the plate and cutlery for scale, and sometimes asks one follow-up question — like 'pan-fried or baked?' — when it would change the number. Tested against 500 weighed meals, it lands within 17% of a kitchen scale, and every ingredient shows what it assumed so you can check it. It works offline and uploads later, reads your weight automatically from Apple Health or Health Connect, and costs €9.99/month or a launch-price €49.99/year, normally €99.99.
What holds up
- +Tested against 500 weighed meals, landing within 17% of a kitchen scale — a stated number, not a slogan.
- +Works without signal — photos queue on the phone and upload once you're back online.
- +Shows what it assumed for every ingredient, so you can check or correct the estimate.
- +Remembers repeated meals — logging a usual meal takes a few taps, no new photo needed.
Mind the limits
- −€9.99/month subscription, or €49.99/year at launch price — no one-time purchase option.
- −Accuracy is 90% over a week and within 17% per meal — an estimate you're trusting, not a scale reading.
