Hi Martin thanks for reviewing and letting me know the Edge 840 was not supported. I updated and you will find all new devices are supported including the Edge840. Also added some minor improvements. Thanks Brian.

After using this data fields for a year, i'm happy to use this as a pacing partner while climbing. But recently i shocked because these power data appear in Strava even though i'm not using any Power Meter. (Shocked)

Lupentacho

Regarding the functionality this Data field is great. But the results on my Bike Trips are disappointing... E.g. Strava calculates average Power abiut 160 W, this field only calculates 70 Watts. Regarding the used calories, seems that Strava was not so Bad .. To correct this mistakes, i Change the Parameter cdxa to unrealistic values... But this is Not optimal... Why Not using the calories information for Generating a correcture facture for the detailed calculated Power... I think with this proposal the Data field is able to correct itself... Self learning after some Rides.... And i think the Garmin Calories are quite realistic... Greetings Peter

It's an interesting data field and I really want to like it but I can't trust it. I'm not expecting high accuracy as I don't use it with a cadence sensor, but It shows 0 watts for minutes at a time when I'm pretty sure I'm putting some effort into pedaling. Maybe I have to tune the settings a little more before it will work better so I will keep it for a while and see how it goes but for now I can't give those five stars (but I want to :). As a complementary note to anyone using this for the first time: initially the data field was showing nothing until I activated the "Calculate Power Always" setting and although I suspected this was necessary I was confused by the app description which stated that the setting should be set to off when not using a cadence sensor.

ottima app peccato sia con i caratteri troppo piccola riesco appena a vederla con gli occhiali di vicinanza

Just one question, as I couldn't find any information about this: What type power is displayed exactly? It is not raw power, that's for certain because of the lag. But is it 3 sec, 5 sec, 10 sec (...) average power it displays? It would simply be nice to know because not knowing what exactly you're seeing is a little, well, counterproductive.

To use the power-calculation in a data field is a very lean possibility. The calculated datas are quiet realistic. I love to use it, thanks!

enable to uninstall epower from Garmin app. How to uninstall it ?

Developer Reply

I received your email but you did not leave a reply email. Remove the data field from the bike app and then it will uninstall. The installing is a Garmin Connect issue not an CIQ issue.

Decent looking app but the data is unusable small on the Edge 130. Can't the text scale?

The application works well on Forerunner 235. Its possible to add the average power of 3s? I think its more important.

I have installed the app in both my Vivoactive 3 and Edge 530. It works fine in both except for one detail: in the Edge 530 the size of the numbers is too small to see while driving. Can you help me?

Congrats for the app, it is very useful. In my opinion an average window of 20 or more seconds (programmable by user) could be more effective to avoid erratic data. My epower and grade graphs are hill and down even if I cycle still and flat. It could be great to have a "power average lap" and "grade average lap" field too, and a full screen version with more customizable fields (like dozen cycle). Thank you in advance!

ManuS5
August 27, 2019 | Version 2.9.1

after few email with the developer, he solved some bugs and made the app perfect! it shows ftp. grade of the road and actual power based on some parameters so no need of a power meter

ManuS5
August 14, 2019 | Version 2.7

The only positive note is that the app doesn’t count watt on a descent so values are more accurate. Otherwise, gradient graph doesn’t show negative values on the connect app and the estimated ftp doesn’t work at all! I always have about 5 watt after a ride..also, I often have high max watt peaks on the statistics but the graph shows don’t show them

Erik Rogne

I would love to see 3s and 5s avg power estimates

Sergio
July 11, 2019 | Version 2.7

It works in my fenix 5x, I can see the average power data and grafic and max power data, but there is a problem with MAX ftp. for example, in one activity of 2 hours I have an 260 power average, but in Max FTP apears only 24,82 watts???. I have cadence and velocity sensors. I don't know if I have anything wrong in my configuration. On the other hand It would be possible to have an option to calculate the power for 3s / 5s to avoid erratic data??? Thanks and good job!!!!!!!!

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

Developer Reply
October 16, 2018, f3b

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