If you have been invited to test the iOS app, installation is a two-step process. Look for emails sent via Crashlytics. In the first email, you will need to allow installation on your phone, and send the ID of your phone. Then we have to rebuild the app and send it out - this can take a few days. That will result in a second email to you which will allow you to install the app. The Crashlytics software will also place a web-view app which you can use to look for upgrades or download again, or you can delete this "app" (the icon looks like a settings gear).
