App del tutto INUTILE! Trasmette soltanto la frequenza cardiaca su swift ma per trasmetterla non serve nessuna app! Basta andare nelle opzioni ed attivare la trasmissione del cardio da polso

Used to pair vivoactive 4 with echelon Fit app when nothing else would work. Requires the companion app but works as described. Great work!

I was kind of surprised at how well this works, but it does work, at least with my Forerunner 235. It's not completely clear from the description but essentially this app transmits your heart rate from your watch to the companion app on your phone. Then your phone re-broadcasts your heart rate as a standard Bluetooth sensor. So for Zwift, for example, I connect my watch to my (Android) phone, then my phone shows up on Zwift on my iPad as a heart-rate sensor. It sounds more complicated than it is, but it does work really well once it's set up. The only downside is I think it could do with some better instructions, either for this app or the companion app.

IQ! shows when using the app via FENIX 5PLUS looks like the app is bug or not compatible with the latest software

The app idea is fantastic but it's not working, The soon as I start the app, it shows me "IQ!" error message. On my phone I can connect wit ZWIFT perfectly, I also did a manual run and works very well.

Craches on venu. Just giving me and small iQ icon and nothing happens :( really wanted this to Work with zwift

Works well on Garmin Venu and but the companion Android app required means you only have 8 mins of recording before you are met with the pay wall. I upgraded and it's been great for virtual cycling in RGT Cycling and Zwift. One Criticism is that the position of the data fields isn't very central on my Venu

The instant you start, The IQ Message appears , Do you know how to fix it
