this app is so simple, but at times it's a bit too simple. the simplicity works for many people, and mostly for me as well, but its missing a few features as pointed out in other reviews. one feature that is pretty important is being able to see previous daily calories. i believe the data is deleted at the end of each day, and some people probably like that, but id like for there to be an option to choose whether you want to be able to keep and see your previous daily calories or to leave them to delete at the end of the day. and maybe even be able to set a time you want them to reset, maybe you are eating past midnight and you still are eating for the previous day. . . i would also like to be able to input my weight from days in the past. . .anyways, sometimes simple is great, but this just feels like it needs a bit more.
