We are using TestFlight (an app that let's beta users access the app early in the App Store) to run our iOS beta test. We expect this beta test to be completed by the end of August 2016.
For those of you who have known us since we opened up shop in Austin (around Apr 2014) we ran a previous beta test with a web application prototype to solicit feedback and do additional research. That application is being scrapped and rewritten from the ground up. We anticipate launching it formally around the time our Android app is launched.
