Users Feedback  (thank you for your feedback !!!)
"I use this app on my every ride. I think this is by far the best power estimation I’ve ever used! "
"Overall, it’s been a great app from the day one since its release. I have used xxxx , and boy it’s horrible. I expect it to be about 100w but it only says like 30w or so. I’ve seen comments and people complained about the same problem. Your app is the one with the most accurate power estimation, and I would love to see it getting better! "

If you encounter problems, please do the following: 

MAKE SURE YOU ARE USING THE LATEST VERSION. THE VERSION NUMBER IS DISPLAYED IN THE DATA FIELD. Make sure you have read all the doc.

- Connect your device to Garmin Connect app
- Update (bluetooth)
- Connect your device to Garmin IQ app (bluetooth)
- Install or update Virtual power 
- Set your custom parameters - nb: some old devices such as Fénix 5, Edge 130 do not support wind correction. Disable it.
- sometimes : sync again with Garmin Connect ??
- Some devices need to be powered off / on to finish the update process

If you still encounter problems :

a) Desinstall the datafield from your device with connect IQ app.
b) Check that it has really been uninstalled on the device
c) restart device 
c) Reinstall the datafield and set your parameters
d) Restart your watch
e) reinstall your datafield in your activity screen

f) In some cases I have been facing the need of a full reset of my watch.  I hope you will not have to do this.

**FAQ:**

**Q: How does it work?**  
**A:** The app estimates power by combining speed, elevation, and wind data. It calculates climbing power from elevation changes, air friction from speed and wind, and wheel friction from speed and tire type. Momentum correction helps with sudden changes in terrain.

**Q: What does the smoothing time setting affect?**  
**A:** The number of seconds sets how long data is considered for smoothing. For example, 3 seconds means the app averages power over the last 3 seconds, while 30 seconds smooths values over a longer period, making the display more stable but potentially less responsive to rapid changes.

**Q: Can the app's power value be used as a Bluetooth power meter for the  device?**  
**A:** When "display in Strava" is set, the power is shown as a native field. However, Garmin Connect IQ limitations mean this data might not integrate seamlessly with device features due to restrictions by Garmin.
