I demo'd this app, along with DietController, and opted to buy this one because it seemed to allow easier food and tracking customization. The "Check In" page is a bit funky, along with the calendar, but once you get used to the way that works, its a snap. Fairly easy to save or enter custom meals or foods, and that saves time for entering certain meals I have on a regular basis. The charts are pretty much the norm as other products out there.

Launches fast, no crashes so far (using daily for more than 3 months),

It's not perfect, and its not the "slickest" looking food management app (DietControllers calendar is neat), but it does the job for me and my wife. I'm satisfied.
