Just saw this app..
https://apps.garmin.com/en-US/apps/9c29c8a2-2fb2-41da-87e9-508f5fb591cb
it's an exact replica (well, except for the added seconds on the ELAPSED time)
been out for a while and all these happen.
Just want to be clear and fair to ifanchi - as stated above in one of my replies - I'm OK w/ the idea usage.
What I wasn't too OK w/ was that it was just a copy (exception on the way the timer is done)
As the app progressed, I can see that it is now supporting HR Zone (this is different - which is good)
Also - I see the desc stating that it is aimed at doing ClimbData which would be excellent.
As it stands right now - there's not much (IMHO) that can be put into the DataFields already - given the current SDK // API available metrics. But then again - humans always surpises w/ ingenuity.
