doesnt work with Apple iOS 7

I loved this software until I updated my iPhone 5 to iOS 7. Now Share-a-bill doesnt work anymore. I can view my data, but if I try to add a new expense the application closes when I try to assign the payee. Will it be updated? My emails to the developer have gone unanswered.

But, before this, the software was great! I track all sorts of shared expenses on it.
