What's My FTP? - Xert

Description

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. Use it during regular riding or use it during FTP tests, if you prefer. You don't have to ...

The app seems to do what it promises, however, the initial experience is sub-par. The configuration options clearly state "reset on lap" -- that's "LAP", so to me, that means the LAP button, not the start/stop button. OK, so that means I can press the stop button for a long pause in my ride, and then press start to resume, and a reset should not happen. To the contrary, start/stop DOES RESET the app, just like, I presume, LAP does. Disappointing after giving it my all, only to find the reading had been reset after I used the start/stop button mid-ride. 3 stars for an average first-time use and lack of instructions. Otherwise, I'd give it 5.

The results provided by this app are very much similar to the one I had for FTP. It is awesome to see a trustable FTP real time.

Be sure errors don't creep into the datastream. Since it doesn't use 8 or 20 minutes worth of average data but instanteneous data instead, errors will be amplified. If you suspect an error, delete the app and reinstall it to reset its internal settings.

Gave results that were almost identical to my 20-minute test. NOTE: You have to throw down a hard effort. I'm talking 90+ TSS for an hour. Load a hard workout, and watch it do it's magic. Lots of these other reviews seem to be user error. The algorithm seems to work.

I really like the idea but can't seem to get it to work. Installed on my F5X and it worked the first few times. But now it is stuck at either 100, 200 or 400 from the start of a ride and never changes even as my power changes. I also do not see the colored ring to indicate progress of measurement.

Try removing and reinstalling the app to reset it to the default settings. Power spikes can cause errors.

Installed app fine on F3 but is it supposed to upload the "determined" value to Garmin Connect? I do not see it anywhere (trial version). Otherwise interesting and will be useful.

Unfortunately Garmin doesn't enable this ability for downloaded apps.

Great tool and seems accurate as well. One thing to improve; let the last FTP stays as baseline for the next ride... Seems I start over at 150W every time...

We had considered that but opted to have it reset to a lower value so you can get a broader understanding of the efforts needed during your rides without having to push yourself to your limit every time.

The previous version has done pretty well with the estimate, maybe even a bit too optimistic identically Fenix 3 and Edge 520. But the current 1.3.3 is something wrong: power intervals 8 min: 220-230W plus rest very light, 1h NP slightly over 200W AVP 1h: 190W (a lot of effort was missing), and this one enumerates on F3: 188W, on E520: 166W. Previously suggested on both 210W FTP devices, and that just makes sense - similar forecasts also give me GoldenCheetah, and in fact so much I should get from the standard FTP test (but I do not want to tire;)), test 2x8min IMHO slightly inflated and after cutting this About 10W the most real maintenance for me for a full hour would be about 205W (with a rising trend;)).

The Fenix and Edge should have identical results since they are using the exact same algorithm. Check that you are not resetting things by either have autolap enabled and/or pausing the recording. This will always result in lower values.

Had no problem with installation on 520. My only power meter is based in a set of Elite Digital Interactive Rollers. The app read this and it seems to respond actively and my FTP was adjusted as I did a workout with 10 intervals ranging from one to four minutes in length. Reading the earlier reviews tipped me to the need to set the app up not to restart on every lap. Seems the default should be to NOT restart with every lap. Installed with Garmin Express on the computer and changed setting with Garmin Connect on my phone, so both of these functioned well with it.

Incredible way to get validation of FTP settings. Thanks!

From one of the reviews I learned you need a power meter. Maybe that is something to add to the description of the app? And how would that work with a watch? Are the power meters for running as well?

Thank you for pointing that out. Description has been updated.

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

Developer Reply

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.

Sorry, no statistics available yet.
