One of the advantages of expo is the fact that ci integration is as simple as doing expo build:ios
/ expo build:android
and you'll get a binary built on their servers. If you don't have mac servers, this is an advantage. I just got their latest newsletter, and they are extending their build service to ejected ('bare') apps in the New Year.
this is great news indeed!
aw I think it's a paid service tho :s
