The vPower data field app has been developed for those who are not fortunate enough to own an expensive power meter. Firstly, this is not 100% accurate. As you can imagine, there is a lot of variables at play to calculate power on the pedals accurately. This is my best attempt to take all these variables into consideration and developed the app with the following key features:</p><p></p><p>Version History</p>


Added support for more devices and more indoor trainers (Jetblack Z1-Pro, Elite Fluid Elastogel (round unit), Elite Elastogel Force Mag 5 (3/5), Tacx Blue Motion (8/10))

Now with the peaks corrected is the best of the bes iq app for estimated power thanks a lot you save me a powermeter!!

I used to be quite happy with the data shown. But the new release with the “no cadence“ option does not make any sense at all. Is there a possibility to use the app without this nonsense?

Respuesta del desarrollador
24 de marzo de 2018, Shane.Coetser

Sorry for that Stephan. The calculation should however work correctly if a cadence sensor is connected.

Great for what it is, downloaded 5 different virtual power data field apps for my Fenix 3 hr, and tested against my Garmin power meter, and this was by far the most accurate and stable. I just wish the data shown, could be uploaded to Connect with the rest of the ride data, is that even possible????

There has been a few issues, but looks like data is now uploading to GC.

You also could match the values that calculate with BPM... With BPM you have another way to calculale Power. Maybe both inaccurate ways to calculate virtual power would be better tan one :) And decide if do an average or a weighted average towards one or another depending of the moment (Changes of bpms, altitude, cadence or so...) As powercal, with a little TEST with a real power sensor at home (in the trainer) you could calibrate or ask for results to get BPM/power rates and so... Then when going outside with any bike without power sensor, trying to estimate it better... In example for me at this moment, at constant efforts aprox: 167W - 115bpm 228W - 140bpm 274W - 159bpm 319W - 177bpm 365W - 185bpm

A few weeks ago. VPower only collect peaks of data while cycling. I replace the sensor but nothing happend. All other sensor on different bikes show the same result. What has happend ??

This should now be fixed.

Is ok in the flat route. During the climb it don't work beacuse don't read the % of slope and set wrong power ( normally from 10 to 70 watt max) . To calcolate the power the reading of the slope is necessary. I hope to use it with the next upgrade .

Respuesta del desarrollador
20 de marzo de 2018, Shane.Coetser

Slope is included in calculation, although it depends on the device accuracy also. I hope latest version shows better results.

Hi, I wonder if other have experienced it, but since the last update I am getting very low values - avg of 25W with a max of 65W... Before the last update it was all working properly - the only difference is that I changed the average value to 10 seconds, I changed it back to 3 in the middle of the ride but it had no effect... Before this update it was working really nice.. any idea? Itay

9 de diciembre de 2017 | Versión 1.80

It doesn't work on my edge 1030. I obtain amazing high power values descending, while power is close to 0 climbing. It seems that calculation is not taking into account my weight and/or bike's, although they are correctly set in my profile (me) and in the data field configuration (bike)

28 de noviembre de 2017 | Versión 1.80

awesome, I use it since the day one, always improving.. the only problem, the beginning of the ride is very often a peak about 1000 watt or more, so the power graph on the website becomes less visible.. sometime I press the start button while moving on a flat road not pushing on pedals and it helps, but not always..

Do you want to send me the fit file so that I can see what parameters are causing the spike please?

24 de noviembre de 2017 | Versión 1.80

Great update now it works and i think it´s very accurate a little bit overestimated on aceleration but when i see the fit in connect i see a peaks with 65500 watts i hope you can fix this thanks

tq for providing the update. now successfully installed at my edge 520. contacted garmin supported previously they said might due to mine is taiwan version...

Bonjour à quand une version pour fenix 5x?

10 de agosto de 2017 | Versión 1.7.1-upd1

Been using the app for several weeks and recommend it for anyone who wishes they could afford a power meter. I would prefer to use the watt/kg option but found the display does not show a decimal value only whole numbers like 1.0, 2.0... I'd like to see values like 1.6, 1.7, 1.8....

Overall it seems to work quite nice. The values are also seem to make sense. There is one problem that I've noticed - often (I could not find any repeatable conditions when it occurs) the power will drop to zero and then after few seconds will climb back. This happens at a time when there is no change in the slope, my cadence and speed. These frequent drops, have dramatic effect on average value which appears to be too low (compared to the values I am getting during the ride). It feels as if there is a memory issue or calculation limit on the garmin device. I am using the edge 1000. Did anyone else noticed this behaviour?

Muy buena! Lo de la gráfica integrada en connect es un punto a favor pero creo que debería hacer una estimacion de 3 o 5 segundos porque al ser instantanea fluctua mucho y, aunque seguirá siendo estimada, será algo más fiable. Todas las salidas me ha marcado bien pero hoy me marcaba al revés, es decir, subiendo me daba 5 wattios y bajando se ponía a 200 o más, es como si los cálculos con la pendiente los hiciera al revés.

11 de abril de 2017 | Versión 1.7.1-upd1

La aplicacion marca siempre la potencia instantánea y varía mucho. Deberíamos poder ponerla a 3 segundos o 5 segundos. Donde puede que la estimación sea más acertada sería en puertos. Pero aun así es un estimador. Seguiré utilizandola. En Garmin conect aparece una gráfica y la media y máxima potencia. Un saludo. Y espero que sigan desarrollandola.

2 de abril de 2017 | Versión 1.7.1-upd1

Great job! Only one thing: I don't know if it's possible to detect if GPS is off or if a trainer is connected and then turn on the trainer mode, and switch if off as you detect GPS is ON.

This is great and I think it is accurate. I really like to see the graph in Garmin Connect, but should show the average and maximum power in numbers. But it's great, Congratulations and very good work. En Español, -Está genial y creo que es certera. Me gusta mucho poder ver la grafica en Garmin Connect, pero debería mostrar la media y maxima de potencia en numeros. Pero está genial, Felicidades y muy buen trabajo.

Great app. I'm using it for dedicated intervals on a trainer. Since I use a Cycleops Super Magneto Pro, I would love to see its power curves added to the app for the fifths star.

I've been using it for a week and think it's great. I don't know how accurate it is, but I like to see the trends of the numbers and"chase" down certain wattage during the high intensity parts of my ride. Thanks for developing the app!
