  • Option to scan foods into the app.
  • Save favorite foods and exercise for easy recall and entry.

Bottom Line
Calio stands out from the typical calorie-counting app with its voice commands. It’s ideal for those who need the audio direction and support for entering data quickly. It also acts as a reference, shopping list and tracker.
