iTMSRemote for iOS (iPhone, iPad and iPod touch) is available from iTunes. Link is here
Below is a graphic from it:

iTMSRemote is similar to the TMSRemote client for PC but not exactly the same. It requires the same backend TAP (TMSRemote) as the PC client.
Additionally it supports pinch/swipe/expand gestures. For more info on how it works go to my iTMSRemote help site at http://members.iinet.net.au/~deangelj/t ... Remote.htm
I have had to charge a small fee to recover some of my costs in licenses to produce the app. Hopefully it won't be too onerous. I will be updating the app free of charge with several enhancements over the next few months.
