ProTrack AI in your language

The whole app is translated: onboarding, Today, History, Progress, Settings, the scanner, and the Home Screen widgets. ProTrack AI switches automatically to your iPhone's language. Each guide below is written in its own language and shows the app's screens in that language.

English is the app's primary language and is covered on this page. To use ProTrack AI in a different language from the rest of your iPhone, open Settings > Apps > ProTrack AI > Language.

What ProTrack AI is designed for

  • Logging meals quickly from a photo, a barcode, or a manual entry.
  • Hitting a daily calorie or protein goal, and tracking carbs and fat.
  • Weight loss, keto, low-carb, and high-protein diets.
  • Lifters and athletes who eat the same meals often and relog them in one tap.
  • People who don't want meal photos or a food diary stored in the cloud.
  • Tracking without internet, for example while travelling.

What ProTrack AI is not

  • Not medical advice. Calorie and macro values are estimates for personal tracking.
  • Not perfectly accurate. Photos can't show every ingredient or portion, so review and edit estimates before saving.
  • Not on Android. ProTrack AI is an iPhone app.
  • Not connected to Apple Health or Apple Watch, and it does not sync between devices.
  • Not a coaching or meal-plan service.
