Very unstable!!!!

I was very disappointed as 4€ app in version #3.4 should work correctly. In spite of well working iphone/mac versions, the iPad v. remains very unstable, there is a problem in communication with iphone and mac, moreover the app causes constantly repeating wi-fi connection loosing. Such mistakes are unforgetable for developer. 0/5!!!!!!!!!!!!!!
