The Strange Agency has updated CP 1919 with a release designed to improve performance.
The developers note:
We held off updating our development iPad to iOS 4 while finishing the app to keep it compatible with the old OS, and after launch we found it ran like molasses on the latest iOS. Imagine the horror! A great deal of low-level optimization later: we have a far slicker CP 1919 for you, clipping along at the 30fps we’ve all grown to love. Same great taste, more responsive interface.
Pricing and Availability
CP 1919 1.0 is available now for US $14.99. Version 1.1 is in the approval process.
