December 7, 2021 | Version 3.7
Loaded it as a data field app (was expecting it as a widget) on my Garmin 1030plus but it does not work. Garmin showing realtime power so do not understand why this does not work. Incompatibility?
September 30, 2021 | Version 3.7
Easy to setup and use on Edge 530. Running 2 field screen - Power and FTP. Would like to better understand what the algorithm is following that brings the circle to 12:00+. At age 70 with resting HR=41, max HR=160 and LTHR=140 I find it difficult to reach the top and hold it without being fully gassed. FTP is around 190. Thoughts?

On My 530 it still on 100 and no move from this value...any solution?

Works perfectly on the Edge 1030 Plus

This app either doesn't work, or my FTP is 100 (Hint! My FTP is not 100).

Xert Premeium Subscription is well worth it because it has many useful features than simply measuring your FTP. I'm going to purchase the subscription after the free trial!

Rob S: Seems o give accurate values based on all the different types of tests I've done. The best garmin app i've used by far and one i'd be happy to pay for as a one off. But not £100/yr subscription. Tried the premium service, very good but just cant justfiy the cost per use.

Thanks for another year. Very much appreciated!
Would like to sign up for XERT, but I'm to amateur and time pressed to make good use of it atm. That time might come though...
August 10, 2019 | Version 3.3
Has been a very nice app for the (pretty good estimated!) quick 'n dirty on-the-fly-FTP on my various head units for quite some time now.
But this is not the first time, this app unexpectedly quits functioning. Last time they eventually provided an update. Although, the one hour shedule is new and very much seems to be on purpose. Since I have not updated for some time now (even think I was still on the previous version when it started) it feels like it must have been sleeping in the code to be finally activated recently.
Armando, if this app from now on merely is supposed to be a teaser for your paid XERT services, why not openly say so? And explain, how to get that code for this app. Appp description and your own website still say pretty different...

It was a great data field, but recently shows error: that it is expired and needs a code...

My xert IQ app doesn't work anymore. What means "Xert code required"???
August 8, 2019 | Version 3.3
It's very inconvenient when you try to ride your best and the app instead of showing FTP estimation shows message "enter xert code"
August 7, 2019 | Version 3.3
I've been using this app for about a Year without problems, but now it also gives me the failere "enter xert code" eact time after around 1 hour of riding.
August 4, 2019 | Version 3.3
After some days it stopped working, enter xert code. Lacks information about that code.
May 2, 2019 | Version 3.2
Is this Also functional for running ?

It should be but may slightly underestimate your threshold power. Try it out and share your experience.
November 21, 2018 | Version 3.2
I like Xert and this app just works fine on my Edge 520 plus.
October 9, 2018 | Version 3.2
This won't work on a Fenix 5X Plus? :-/
September 3, 2018 | Version 3.2
App works great. Its fun to watch the your results improve with each ride. With the current update the code error was resolved. I cannot however change the reset to Off for each lap. When I set to off from my PC it does not hold. I cannot edit this setting from the device (Edge 1030) or my iPhone.
August 30, 2018 | Version 3.2
the app is listed on GE and GCM but does show on my fenix 5. what do i miss?

Not sure. It works like any other datafield. Make sure you following the correct app install and configuration sequences.
August 28, 2018 | Version 3.2
Great app. Sometimes it will return a message about expired licence (Yes I have the latest version) but most times it works fine.
August 22, 2018 | Version 3.2
I use is all the time...but after about a month of use is says "Time expired enter Xert code" or something like that. I thought this was a free app?
August 9, 2018 | Version 3.2
Generally a good app but can not update it to latest version. Always says problem with deinstalling. WHat shpuld i do?
July 4, 2018 | Version 3.1-upd2
Just given 3 stars as when it was first installed it was reasonably accurate although easy to spoof and get an extra 10-15 W by putting in a surge in the last 2 mins of an 20 min FTP test. Recently it's stuck on 200 W whether it's getting power from PT hub, Quarq crank or Zwatt crank arm.

For best results, the first time you use the app, perform a Peak Power effort (i.e. obtain your highest power possible) while you are fresh and before you attempt an exhausting effort. Look for an opportunity to put out your highest wattage possible first and from then on you should be good to go.
If previous power data errors are causing it to now show invalid values, simply reset the app using the reset function in the app's settings.

i am struggling to get it to show up on my fenix 3 HR. I have tried to install it several times with resets of the watch, but it does not show up on the programs. Any help would be appreciated.
