Logging for past days

Natalie
I have seen many people asking this question - but never actually seen an official reply from support.
To me, the ability to log things for past days should be a standard feature in any app like this. 
I'm not going to immediately pull out my phone after having sex to log it!
Is this something that Ruby is fixing? Without this feature the app is only half usable, I love the design and feel, but the tracking won't ever be accurate, and therefore is not helpful. 
Can I actually get an official answer on this?
