Works perfect with my elliptical on running apps
I am forced to work out indoors since it is now over 110° in Phoenix. I paired the QZ app with my elliptical which at first had a few bugs that Roberto worked out with ease. Very happy now I can run indoors with my running apps.

Great App!
I had trouble setting this up. I contacted the developer and they responded within a few hours. App is now up and running with my peloton bike and it does exactly what I want wanted it to. Great app and fantastic support.

It drains battery very fast
I used on a iPad and only work on a rower for one hour. It drained 68% power. The battery log said I used 6 hours. No sense.

Phenomenal!

Bait and switch
Bought the app and installed it on my Nordictrack. Can only get 80% of the functionality to work. Contacted the developer on Facebook, did a bunch of debug and still can’t get it to work. Developer asked me to jump to another monthly subscription and still not working. Stay away from this guy.

Terrifically useful app
This app allowed an Echelon bike, in a small apartment building gym, to be used with third party apps. A firmware change made this impossible, but the developer worked diligantly to find a solution. The app now allows the formally practically useless Echelon bike to become a “virtual” smart bike. I cannot praise enough the developers responsiveness to queries nor how customizable and how perfectly the app works.

Great app and support
I was unsure if the equipment was compatible and Roberto got to me very quickly and helped me confirm.

Great app!
I had given up on connecting zwift to my 2020 keiser m3i. I upgraded the bike “computer” a couple of years ago to add Bluetooth and it connected to zwift no problem. I lost interest in zwift but recently tried it again and zwift apparently changed their connection protocol and I could not connect no matter what. Enter QZ! Run the app on your phone start peddling, connect to the bike with qz, open zwift and voila! Amazing job, Roberto!
