How we picked

This list is made by the Nutrilogy team, so our app comes first — we'd rather say so upfront. The others are popular App Store apps whose descriptions explicitly mention logging food from a photo. Ratings are from the US App Store as of November 6, 2026; features are taken from each app's own description.

How to choose

  • Check whether the app recognizes several dishes on one plate and shows the portion weight — that is where accuracy comes from.
  • Make sure you can fix a result: change the weight or add hidden ingredients by voice or text.
  • Apple Health or Health Connect sync lets the app count your steps and activity.
  • Use the free trial to test accuracy on your everyday food, not on the photos from the app's ads.
