Master Server alternative for iOS basic LAN multiplayer?

I’m trying to create an iOS multiplayer game using peer-to-peer networking. I wanted to implement it so that players could just hit one button to be placed into an already existing game or create a server if there was not already one (similar to Spaceteam’s design).

I created all of the networking code using Unity’s built in networking and even got the Master Server working but once I tried to put it on my iPhone I found out that it’s unavailable on iOS without Pro. Is there some alternative that works similarly to the Master Server solution?

If you’re stilling searching for an answer, if you’re up for some C#, I recommend the Photon Networking Engine. It does NOT require a pro iOS/Android license, and you can find it here:

Here is a handy tutorial for it:
