Short answer, everything worked great!
I logged into the iPad first then Zwift on my laptop. I got my bike setup and paired with the laptop and bike computer (JouleGPS). A few seconds after choosing “Just Ride” and starting to peddle, the App screen automatically switched to the stats screen. After warming up, I swiped to the other screen and choose a few random gestures, and sounds (I did not hear the sounds because I have Zwift on mute and stream music). After a few laps and getting the 50mph achievement I ended and save my ride using the App. I really like ending the ride with the App because I am better able to stop both Zwift and JouleGPS at the same time.
I also installed the App on an iPhone 4S, and will test and review that soon. I look forward to testing the Droid App if I get chosen.
