Cylack

This is by far the best calorie counting app. It is easy to use, syncs with Apple Health data, and has a robust database of food and free UPC scanner to input food. Other apps I have used in the past started charging for UPC scanning ability. Also, the paid features of fatsecret look good with dietician designed meal plans. I may try premium in the future. There is no reason to be paying for other apps when fatsecret has everything you need in its free tier.
