Gramwise uses your iPhone's depth sensor to measure how much food is really on your plate, then tells you how much protein you're getting. Smaller portions leave less room for guesswork.
Launching first on iPhone 12 Pro and newer. Photo mode for other phones.
NIH researchers tested four popular photo-based calorie apps on more than 100 lab-prepared meals. On average, every app underestimated each meal by this much, and missed about 30 g of fat.

Most food apps guess portion size from a single 2D picture. A half-cup of yogurt and a full cup look almost the same from above. When you're eating less, a 30% miss on protein is the difference between hitting your goal and losing muscle.
Two seconds. The LiDAR sensor in iPhone Pro models reads the height of every item on the plate.
It separates the foods, measures their volume and converts it to grams. Scan a bowl once and it remembers the shape, so soups and noodle bowls work too.
You get grams of protein per meal and a confidence range. If something can't be seen, like oil or a sauce, it asks one quick question.
Daily and per-meal protein targets come first. Calories are still there when you want them.
Couldn't finish your plate? Scan what's left and Gramwise counts only what you ate.
Log injections or daily pills alongside your food so you can see how your appetite changes through the week.
Export a clean summary of protein, weight and meals to share with your doctor or dietitian.
Scan your usual dishes once. Every scan after that is more accurate.
