Needs updating
I have been using Billings since Billings 3 and have enjoyed the Billings Touch app. This is even greater for me, because it syncs in the cloud. But... I would have expected ios7 interface updates. The old keyboard is horrible. Please take care of this. But functionality is exceptional. I have never had issues with Billings Touch or Pro.
