Well, let that be a lesson for you. Record your foods daily. I think it's a good practice.
Look at it like this. You're either serious about tracking or not. By skipping report days, as you suggest, it does the following:
1) Gives phony data. So what good is the data if it's not accurate?
2) Makes a person think they're "serious" about tracking when in fact they are not. Being dedicated and serious is to track DAILY.
3) You're asking for this option to be implemented, encouraging a more unhealthy lifestyle by supporting the of skipping days.
4) You're asking for a programmer to take time to develop this option, just to support #3, which is not a good enough reason.
I think FitDay HAS IT RIGHT.
Think of food as fuel for the body instead of feeding emotions
