I have enjoyed it so far

While I am new to using Expo, so far my experience has be delightful. With open sourced dev tools I often run into at least one issue getting it set up and working. Not with this. Developers keep up that good work!

Easy for developers, not so great for users

While it’s quite fantastic what Expo has managed to do for the developer community and RN, the majority of the apps I have come to use and test often feels cheapened and watered down. Sure, it’s nice to “get 2 for the price of 1”, but maybe instead of being so focused on making the lives of developers easier, it also makes sense to consider the quality of apps that are being released into the ecosystem. It is regular people, after all, and not just developers that use apps.

Incredible Tool

I was pretty overwhelmed at the idea of getting started with building a mobile app. Expo takes care of all the tedious bits so you can focus on building features. Can’t recommend it enough!
