YES, yes, you CAN, set the UIRequiredDeviceCapabilities stating that the app requires telephony. This means it will only work on an iPhone. Please read more about it from the Apple Documentation here –

UIRequiredDeviceCapabilities – setting conditions so app store knows which devices to allow installation on

Within this page, search for UIRequiredDeviceCapabilites and it will tell you more from there.

I hope this helps anyone with this issue
