Thanks for reviewing, if you do not have a cadence sensor set Always Calculate Power to On.

Congrats for the app! It is very useful to have an idea of the power developed! As Antonio and others, I see the three graphs, but I cannot see the Average Activity Power data, Maximum Activity Power data (I can guess with the graph), Max FTP data (I can guess with the graph as well). In the reports section these data are empty. Thanks

Hello. I use a edge 820 to go to work, if I pause and turn off the ciclocomputer, when I restart after 3-4 hours, I wait for the GPS signal, but I have an error until restarting a new workout. If i use in continuos, this is a great app.

Hello, I am installing the application and it does not work. First field I have the Dozen of Cycles and the second field I have established 4, with epower, FC, Speed ​​and FC Zone. My question is, does the Epower application work with a cadence sensor or only with the gps? Thank you

thanks for the review, If you do not have a cadence sensor, check the 'Calculate Power Always.

Hello. I think it's a very interesting application. I see the maximum power information and the power and grade graphs. I can't see the average power data. I have a cadence sensor but it indicates power without giving pedals. Finally, is it possible to use garmin the power data for the VO2 calculation? Thanks

thanks for the review, there is a setting in configuration that stops power when not pedaling.

Enjoying this, thanks. I maybe missing it but can't seem to get average power in garmin connect?

thanks fro the review, Soon this datafield will be updated to the power that is in DozenCycle.

e-Power is the best app, thank you ......... but in the flat it shows too little performance, is the correct? Thanks in advance.

Thanks for the review, I'm looking into different calculations for estimated power.

nice update about cadence but estimated power is still very low on flat maybe you should compare the formula with de omnifield https://www.gribble.org/cycling/power_v_speed.html

Thanks for the information, i will look into this approach.

Previously rated 5 stars but now I only get a zero reading and an empty curve because I don't have a cadence sensor. Same with the competing apps so I guess I'm left with nothing. Ironically since I ride fixed gear I can't stop pedaling no matter what. ::

Sorry i will make that an option to select!

very bad calculation omni bike, vpower, power4bike, has better calculation it needs 10 second interval, not to calculate when not pedaling and the omni bike formula on flat

I made the change to zero power when zero cadence in v2.0, im going back that out of the code and make it a configurable option.

Works well. Saving max and average power to garmin connect would be nice. The vpower datafield does, but doesn't work for me for other reasons. I would assume that calories based on this value would also be interesting to know.

perfect! can you do a version por MTB? I have a road bike and MTB and the estimated power is different. thanks

Cette application permet de gérer beaucoup de paramètre, comme la surface de contact, le profil de l'athlète, une estimation du rendement... Toutefois l'estimateur de puissance se base essentiellement sur les accélérations et décélérations ou en fonction de la pente ou de la descente. Sur le place à vitesse constante, même à 40km/h, il affichera 50W. Puisque la montre est connecté au téléphone il devrait pouvoir avoir accès à la météo et connaître le sens du vent et ainsi mieux estimer la puissance. C'est donc bien ce qu'il propose mais ça reste énormément perfectible.

Thanks for the review, but getting internet wind speed is very unreliable. And would add another unknown variable that could cause eratic results. Maybe if Garmin invented a ANT+ wind speed sensor?

Great Companion app to Dozen Cycle Estimate Power and %Grade are ~95% accurate compared to other riders with the $$$ power pedals getting similar power readings.

Sorry, no statistics available yet.
