Congratulations on the launch of your Beta testing! That is half the battle. My advice would be to slowly do another round of Beta testing and inviting people who you know will give you good feedback and help you improve your app. Then in the mean time get PR to pump up your app again for launch in a month.

Not every app when it launches is perfect, we all have to update apps on our phone constantly so do not be afraid to go live. If you would like to set up a phone call I would love to chat more in depth because I have two friends who have get apps that I may be able to connect you with who have been in the same shoes as you!
