1) It doesn't always upload the activity to Garmin Connect. Strangely every once in awhile it syncs and brings Connect activity down to the phone, but still doesn't upload the missing activities that are on the phone, but not yet on Connect. How in the world do you force them to upload?
2) I'd like to see the ability to add more data choices to the main screen or at least be able to choose which data field to display. They chose instant pace to display on the first screen, which is a waste because it's too jumpy and delayed to be of any use. This isn't unique to this app and instant pace is a waste of time on most apps and even GPS watches. Instead I'd love to be able to swap that out with lap pace or average pace, which is much more reliable. After you complete your first lap you do get an additional screen showing "avg pace" but I think they mean avg pace on the current lap. They should re-label that as "lap pace." It's also strange that you only get this added screen after you have completed one lap. You almost would rather just hit the lap button 1 second into your run just to get the added screen...kind of klunky.
3) I have a Motorola Photon, which is already known for excellent signal and GPS, but Garmin Fit in my tests seems to overstate my distance compared to Endomondo and Runkeeper, which are always close to my car/pedometer/web-mapping.
4) A dedicated Fit App forum here so we can track the development in a community dedicated to just the Fit App.
