I would be really handy to have an offline mode for the Garmin Connect app.
I appreciate it needs a connection to upload you FIT data to your account on the web and show you a map of the route etc
But when you are in remote locations without a connection it would still be nice to still be able to sync/save the data from your watch etc with the app and see the data on the larger screen without the need for a connection. It could then upload the data the next time you are on wifi/4G
Thanks
