Expo

Good at simply being a virtual device on your physical device, but opening the developer menu by shaking the device was a terrible idea. There is no way to stop remote debugging. EDIT: Here I am a few years later. I better understand Expo and development overall. I was very frustrated and overwhelmed b/c I was learning everything on my own. Expo has been instrumental. I know I am not using all the tools available to me, but even just for simulating on a physical device, it's doing it's job well

Expo Go has always been a part of our workflow and works well, but the new-ish limitation of only working with latest version of Expo SDK is a bit annoying. I have had to turn off auto update but previously when the app auto updated it forced us to immediately upgrade to continue using Expo Go which we weren't quite ready for. Additionally as a feature request, please as the three finger touch to bring up the dev menu like iOS Expo Go has. Thanks!

As long as your app works and doesn't depend on native code, then it works like a charm! One thing to keep in mind and wish there could be a workaround (possibly code pushing where users opt-in to expand support for earlier versions??), is when it updates for new Expo SDK versions, it removes support for earlier versions. As long as you understand those limitations, then this is a great tool for React-Native projects.
