I'll confess, I'm not nearly as organized as everyone else, but I do try to plan. I have just a plain old notebook that I write in. I know, sounds very primitive, but it seems to work for me.

I know that based on my schedule I use my calories at certain times of the day. I know that I will use 200-300 calories in the morning and another 200-400 at lunch, and so on. So, my goal everyday is to stay within my range. If I don't plan..well...it gets ugly. I have a few options at breakfast everyday that fit into my normal range, cereal, egg substitute and toast, or sometimes a turkey sandwich. Same for lunch. So I change things around all the time, but it all has to fit. I can fill in some meals a day ahead if I know my plans for the day. It really takes the pressure off and I'm much less likely to think about what I could be having if I have already committed to my choices. HTH
