This is the first app review I have ever written. But this app is so great I had to. Beautiful, intuitive app interface, clear communication of data, very simple layout, easy to navigate. It communicates seamlessly with my iPhone "health" app and also with my EasyHone digital scale app. The library of foods to choose from to register what you ate is gigantic, you will never have to write your own just adjust the serving size to suit and you are good to go. The "create a meal" function is awesome for saving complex new recipes so you dont have to re-so then every time you need to enter that food again. And its free! The in-app purchases dont affect any of the real in portably functionality of the app. But even if I did, Id pay. This app is that good! 55 year old male, first nutrition/weigh loss regimen Ive ever done. This app makes it fun and easy to track calories, exercise and more. It makes a tedious chore fun.
