What's My FTP? - Xert


This revolutionary new app determines your FTP *on-the-fly*, continually updating and increasing the value the harder you ride. Using a sophisticated Xert™-based algorithm, the app uses patterns in power data coming from your power meter and looks at how you fatigue to provide an estimate of your FTP.

I have an edge 820. Downloaded using Garmin mobile. Only getting "IQ!" on data field on unit. Any suggestions?

Try and restart the unit. If that fails, uninstall and reinstall. The app is pretty simple and should work without any issues on the 820. If this still doesn't work, you may want to contact Garmin to see what they say.

is necessary sensor of power? because I have a 520 without sensor of power and I ride 1h and all time I see 100w

FTP means "Functional Threshold Power" and you will need a power meter in order to use this app.

Sounds good on the paper, but I don't understand why value is reset to 100 many times during my ride. I'm using Fenix 3, with auto-lap 10km. Is reset applied at every lap ?

There is a "Reset on Lap" setting that you can disable using Garmin Express or Garmin Connect Mobile.

Got it working on my Edge 520 with the latest firmware 12.10. Added a new screen an displaying 2 fields with Power and the My FTP app. No issues so far.

Tried it out today on a Fenix 5x. Seemed to work sometimes. After the 5 mile lap it got stick at 100 and didn't do anything. Also, there's no rings, just a number.

I have a Garmin Edge Explore 1000 and I haven't been able to get this to work. The data field is on my device. I have it setup for it's own separate screen. I have a stages power meter. All it gives me is IQ with a little yellow circle with and explanation point in the middle of it. I've tried to uninstall it and re-install it, but that didn't work. What am I missing?

Try using Garmin Connect Mobile rather than Garmin Express to install and setup the app. This often can work better.

Test of the FTP app by BaronBiosystems/Xert with a Power2Max powermeter and Garmin 520 FTP value initially stabilised at 177w but later during climb effort recalculated and showed 185w Rode at several different exertion levels including some max efforts. App is very simple and it is easy to see when calculations re initiated and when they are completed.

not getting the fancy graphics on my 520 - just the number

Strange. We've not seen this issue at all. Do you get colours when you use it on profiles with multiple fields?

Ian Blackburn

This is a data field, not an app - so I guess that is why I only see the number and not the coloured rings show in the screen shots on an FR935? Or am I missing something?

July 18, 2017 | Version 1.3.1

No color ring, as on screenshots, in Fenix 5

No issues on the 5X that we've tested with. Which model do you have? We're the numbers affected?

Sorry, no statistics available yet.
