Photo Facts
* An AI estimate from one photo, not a lab value. % Daily Value uses the 2,000-calorie reference on US food labels. In the app, you set your own goal.
Directions
For every meal. Set your targets once, before the first meal.
Set your goals
Tell the app about yourself and your goal. It suggests daily calorie and macro targets from standard formulas. You can change them.
Snap your food
Take a photo of a meal or snack. The AI finds the foods and estimates the portion, the calories, and the macros.
Check the estimate
Hidden oils, sauces, and mixed dishes are hard to see in a photo. Change the portion if it does not match what you ate. Then save.
See your day
Each meal adds to your daily totals, so you see how close you are to your targets.
A photo gives an estimate, not a lab measurement. A kitchen scale is more precise. Many people log by photo every day and weigh food when they need more detail.
