Bad program

I have iphone 4s, ios 7, macbook pro, cubase 6.5. After i start the app it hangs for several minutes and only then finds my computer. After a minute of usage - remote controlling - app hanged again and cubase on computer hangs too. Full of bugs app, i will not use it and on stage a fortiori. And i wont risk buying pro version for 13 bucks
