First let me say I really like this app. I ran a couple different apps for a few days and chose this one because I liked it better.
There are a couple little things that would make it so much better though ...
1) When I add a food and tap number of servings, select the existing data so I don't have to backspace to delete it, I can just type in my new size.
2) From the view that looks like a notebook page ripped at the bottom - I get here after saving a meal - if I tap back I leave the app. I would like to go to the main view with the calorie slider again.
3) If I go over calories for the day, display the number of calories I am over on that main view.
4) I do the same exercise every morning for the same amount of time, and the same exercise at night but the time/distance varies. It would be nice to have a recent or frequent here so I don't have to enter them from scratch every day.
5) on the Meal view show the total number of calories I have entered so far for that meal
