it would help a whole lot if you would put d1 pocket crono as an option. I can not figure out which option to pick. I pick the one below the words newer model and the text that pops up says v2 not D1 so I have no idea how to use this app. I am trying to get everything ready for when my D1 arrives but I'm stuck on the very first screen. Just make it easy on folks and put D1 as an option. i have to give it 1 star for now for this reason. maybe once the D1 arrives I can give it more stars.
