Point your camera at any meal and PortionSnap estimates the calories, protein, carbs and fat for you. No searching a food database, no weighing, no typing out every ingredient.
Take the 60-second quiz →Take a photo of your plate, or just type or say “two eggs, toast and a latte.”
See each food with its portion, calories and macros. Slide a portion up or down, or correct it in plain English.
Your daily ring and protein bar update instantly, so you always know what's left for the day.
Most calorie apps were built around a food database. PortionSnap is built around the way you actually eat.
Log however is fastest in the moment: a picture at dinner, a sentence on the go, or your voice while you cook.
Every food gets its own portion slider, because “a bowl of pasta” can mean 300 calories or 900.
“It was three eggs, no butter.” Type the correction and the meal updates. No digging through menus.
Your plan sets a protein goal alongside calories, so you're not just eating less but eating better.
Runs in your phone's browser. Add it to your home screen and it opens like an app.
Searching for “chicken stir fry,” picking from 40 entries, guessing grams. PortionSnap turns that into one photo and a glance.
See my plan →Illustrative comparison of the steps involved, not a measured study.
No barcode, no label. Snap the plate and get a sensible estimate for each item, then nudge the portions to match what you actually ate.
Get started →Portion: 0.5× medium serving
Your quiz sets a daily protein target. Every log fills your protein bar, so you see at a glance if dinner needs a little more.
Find my protein goal →Photo estimates are a fast, sensible starting point, not a lab measurement. Accuracy depends on the photo, hidden ingredients like oil and sauces, and portion size. That's why every item has a portion slider and you can correct the meal in a sentence. Consistent, quick logging beats perfect logging you give up on.
