I was able to install the app on my Garmin 920xt but had to jump thru a couple of hoops to get there. On Garmin Connect, when trying to download the app I get an error message that my 920xt software has to be compatible with IQ 1.2.1 SDK, which is not the case for the latest 6.20 software available at the Garmin website. I had to get the 6.26 Beta downloaded and installed on the 920xt in order to be able and use WhatchOut! (WO!). Anyways, after this is done then it was just running thru the process of creating a profile on the WO! website and adding the cards. Then I had to go back to the garmin connect on my phone, put my login info for WO! and synchronize. I say that the whole process is about a 6-7 in a scale of how difficult it may be for non-tech savvy users to go thru all the paces. I know that WO! will continue to grow and evolve as they get the user feedback, I really commend you on your work. The app is working fine on my 920xt and have used it at the gym and the supermarket.
