It does work with my Ipod touch OS 5 but there are lots of annoying things:
-strangely 2 Seconds is rather 0,5 Seconds, so unusable
-next step is 10(!) seconds which is to long
-the double beep indicator that should be on the 9 or 8 is actually on the 10 when the photo is taken (lol)
-you won´t see the photo afterwards, you´ll have to the menu
-seems to be no way to delete taken photos you have to go to the main Photo app
Makes me wonder what Version 1 was like:)
But it´s cheap and it works so 3*
