Exponent apps have URLs, so if you have the URL for an Exponent app, you can just download the Exponent developer app from the iOS App Store / Play Store and then open the URL.

Ex. Try opening https://getexponent.com/@exponent/floatyplane from your phone.

If you have the source code for the app, just open the project directory in XDE (our desktop software) and it will give you a development URL that you can open in the Simulator or on your phone.

In general, testing Exponent apps is way easier than testing apps other ways. We put a lot of time into making it simple.
