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 worry about pacing or interruptions. Just ride as hard as you can, right to your limit, and you'll then have your FTP.</p>

Glad the developer is active responding to feedback! The app is very cool. I didn't realize that the FTP resets every lap button press until I saw their notice about that; I had thought that the app was just experience errors or I needed to update it or something. Definitely going to toggle that off for my riding since I have autolap enabled on my Edge (I don't need it resetting every couple of minutes - 5 miles). I think it should be more obvious that the app will reset its FTP estimate every time there's a new lap.

It’s great but it doesn’t work with the latest edge 820 firmware update. are you going to fix it?

Nothing has changed in the Garmin ConnectIQ platform that requires any changes to the app software. Try using Garmin Express and/or Garmin Connect Mobile to re-install the app. Perhaps there was an error that occurred during the firmware update process.

By far the best Connect IQ feature I have found. It will be my method to gauge my FTP for this season. Many thanks to the developers.

Loved it when it worked. Stopped suddenly working. Wonder if it has anything to do with 12.50.

The FTP calculation resets when ever you click lap on you garmin, rendering it useless during an interval session.

Simply great. The app works well on my 520. I've tested the app for 2 month in several trainings & a lot all-outs now (I was very sceptical) & I'm sure: it works. Furthermore the numbers at the display motivate me during the all-out which is also a big plus. Bye bye old (& horrible) 5 + 20 test. Welcome What's my FTP app. Great Job Xert. Thanks a lot :-)

Seems OK, but I cant remove from my 520 unit, either remotely using Bluetooth and my phone or when plugged in via USB to my PC?

I am very interested in this app! I am having a problem with my iphone 8 as it says it can't update the latest update though. States that it has an uninstall error. Any thoughts, as I would love to update. Great app otherwise!

Is it possible to save the data of the ride to Garmin connect?

It's really a great and motivating tool ! Congrats for building it ! A feature that would be very nice is the possibility to show at the same time : - the FTP of the day - and the FTP of the lap. Is that possible ? Vincent

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.

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.

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...

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;)).

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.

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?
Sorry, no statistics available yet.
