Great app, it is always in my Edge 830!both in real-life riding and in Virtual riding (Rouvy) I wish the display is in kj instead of % like is in GoldenCheetah. All the research papers including all the data from Dr Skiba is in kj Again thank you very much for this great app

App data field is blank on my Garmin Edge 1040 Solar.

Updated to last API and it should work. A greeting.

April 21, 2023 | Version v3.4

edge 840 update please :)

April 10, 2023 | Version v3.4

Useful to monitor training efforts above threshold

Nice to be able to overview the body battery while racing. Great app.

November 4, 2021 | Version v3.3

Unfortunately it doesn't work with Stryd powermeter.

August 27, 2021 | Version v3.3

what does tau means? and how can I chage it in app?

This is great on my Edge 820, but why not working with Fenix 6 watches if it works with Fenix 5?

June 16, 2021 | Version v3.3

Hello! I wrote another review elsewhere, but thanks for replying in there. It is a pity that runners cannot use your app with Garmin Pod since you cannot use this data, as Garmin does not make it available. Any idea if this will happen any soon? Thanks!

The most needed app in my Garmin. Thanks!

May 23, 2020 | Version v3.3

Is it possible to adjust TAU value in order to w' recovery be more slowly?

April 19, 2020 | Version v3.3

It doesn't work on my edge 830..always display 100%

Hi, Have used this app on the Edge 520 in the past and enjoyed it. Simple and effective. Any chance of making it available for edge 830 and 530? Thank you

Glad to see this app - I wondered when someone would try to implement it in the garmin. It does seem to use battery on my garmin 820 really fast and I found recharge rate really slow compared to what golden cheetah workout editor predicts. Although I think golden cheetah seems to show recharge to be too fast I think compared to the maths I have looked at from phil skiba - any ideas?

Hi! MattinG, I have been using your app and I love it, I think it is an essential complement to my potentiometer. It works great and it matches perfectly my capabilities and it has even helped me to calibrate my CP and W’. Just one minor remark. The time to exhaustion (in my opinion one of the most useful data) is very variable. It is not the app´s fault, it is just the nature of how powermeters work when instantaneous power is involved. That is why most of us use 3 or 5 seconds power as “instantaneous”. So, my suggestion/question would be if it is possible to implement some kind of rolling average (maybe the last 3 or 5 seconds) to the time to exhaustion, so that the value is more stable. Anyway the datafield is amazing, thank you very much!

May 20, 2018 | Version v3.1

Now it works perfect for me. Quick support from the developer that reliable synchronisation only works with Garmin Connect app. I like to use it in combination with the w/kg data field to get a better feeling when to save energy or speed up.

Siempre me ha funcionado perfectamente en mi Edge 520 pero desde que puse la última versión, al rato de haber iniciado el ejercicio, me desaparece el campo y me aparece en pantalla el simbolo de IQ. He probado a desinstalarlo y a reinstalar, pero me sigue pasando. También he observado que la grabación de los datos aumenta considerablemente el consumo de batería. Un Saludo.

Normal that consumes battery if saved in file FIT, that is why with version 3.1 has the option to disable the saving of the metrics. I find your assessment very unfair without having configured correctly and having consulted before.

Please add an option to disable saving the data to the ride.

Don't work with the new Garmin Edge 1000 Update 12.1 12.2 The last version that work is 12

April 12, 2016 | Version v1.4

v1.3 was working great. It would be nice to be able to set the font color to just black though. When i upgraded to v1.4, I now just get a data field with "IQ" and a "!" in the middle of it.

March 30, 2016 | Version v1.3

Nice app. One question though: could you add the current 3s power to the datafield. When doing intervals I would also like to see the wattage I am currently doing next to the depletion / revocery numbers. Would be great!

March 20, 2016 | Version v1.3

Top App !!! Thank You
