I see a lot of similar apps in the App Store. I'm sure you are aware of that, but it never hurst (much) to mention the obvious.
The only other possibility I can think of is to use a remote desktop app to run the desktop version. I don't know how well that will work, translating mouse to touch. Probably awkward but not impossible.
The two most popular apps are LogMeIn Ignition and SplashTop.
