This is a remote control app for members of the R2 Builders Club. Apart from looking pretty, and playing sounds (if you upload them to the application), it doesn't do anything unless you are building an R2-D2 replica robot and have MarcDuino receiver boards (as described in www.marcduino.com and on my build log on Astromech.net). If you do, lucky you, it will allow you to control the dome panels, holoprojectors, sounds and dome lighting of your Droid in all sorts of interesting ways. You can see a demo of how it works with my R2 here: http://www.youtube.com/watch?v=AUod3LRQ1DI The app can run all the way down to iOS 8 on an iPhone 4S. The app doesn't include any sounds by default. If you want sounds to play directly from the app or through Bluetooth, you must upload your own sounds files to the App using iTunes. The sound files are typically the exact same you'd use in your remote sound system of the robot such as my MP3Trigger setup (described on www.marcduino.com). Commands, in the form of programmable short ASCII strings, are sent via the internal WiFi iPhone radio to a remote WiFly receiver. Alternately, the app also generates a 9600 baud serial output stream on the earphone audio port. This way you can send serial command to an external XBee transmitter radio for a more reliable link. You'll need a small level adapter board to use the audio serial capability, also on www.curiousmarc.com. Since you can customize most buttons and commands, you could also use this as a generic remote control app to send any short serial string via WiFi (to a WiFly radio fore example) or serial link (through an XBee). And with a spiffy R2-D2 inspired interface to boot!

Verdict
The clearest difference is review sentiment: R2 Touch at 80% against zComms's 33%. R2 Touch also leads on iOS requirement (8.0 vs 12.0). zComms's advantage is price (Free vs $5.99) and update cadence (monthly vs every 10 months). On ads, in-app purchases and device support there is nothing between them.
