Fun little App, Great support!

I originally purchased this app and was having difficulty getting it to work as advertised. I contacted the developer, who responded by email within 24 hours, and who followed up the next day when I had not been able to respond to him. I eventually was able to get the app to work and it is a fun little thing to play with. I recommend it! And I am very appreciative of the excellent support offered!
