Latest app will not work with the Edge 1030 it appears it doesn't communicate with GCM to auto update the signature now I am just stuck with the default 1200 MPA.

You may just need to start a recording to get the app to fetch the new values. It might take 5 minutes or so. If you happened to have done a hard reset on the 1030, it unfortunately may then take a few hours. Issue we let Garmin know about.

Wrong values concerning MPA ... on yesterday's ride I should have had at least three Breakthrough efforts (although MPA value decreased too fast in my opinion), my garmin 1000 showed even a breaktrough badge ... in the end on xertonline I had not even one. may be a good approach, feels embryonic.

Try configuring it with your Xert Code. It will correct the errors in MPA.

I love this app and everything that stands behind it! I have two comments though: 1. The MPA field seems to have a wrong value. My MPA in xertonline is around 800, but the app on my Garmin has it as 1200... making it ineffective. 2. While I fully understand the math behind TrainingPeaks, Xert has a bit of a learning curve, at least for me. I tried to load "all" the xert apps into my Garmin 520, but then found that it is limited to 4 ConnectIQ fields, forcing me to choose some xert metrics over others. It would be great if Xert could provide a single app (datafield) that has all the relevant metrics, and have Garmin refer to it as a single ConnectIQ. Nevertheless, very interesting approach to training!

Formatting a multi-datafield app for all the various screen sizes and activity profiles is the main challenge. We are considering a number of updates including what you're suggesting as well as a new apps with additional metrics, improved algorithms and reducing reliance on Garmin Express/Garmin Connect Mobile for configuration. Thank you for your comments.

Is this going to be available for the 935 anytime soon?

GasDoc - email me directly through Cycling Center Dallas and I will walk you through setup. It's not Xert, it's Garmin.

When I enter my Xert code Garmin Connect closes. It does restart and reconnect to my 520 but I am still unable to successfully enter my Xert code. Android 6.0.1 Any advice - really want to make use of this IQ app - looks interesting. Happy to beta test any fixes or provide diagnostics.

Okay - if there was ONE APP that could alter your training and testing and competitive nature forever, THIS IS IT! Used in conjunction with XertOnline, you'll be able to actually determine, in REAL TIME, your Maximum Power Available, and see JUST HOW MUCH JUICE you have left in your system, for any interval of time! Use for interval training, use in rallies, use in racing, all of it. THIS IS GOLD!

Sorry, no statistics available yet.
