Wonderful so far, but what about sync? – Knitting Chart Review

I’ve been really enjoying the iPad version of this app, enough that I bought the full version. But do I also need to pay for the full version separately on my phone, and how do I get my projects to sync between devices if I did do that? I don’t want to remake my entire project on the phone version just so that I have it on both devices.
