Comments on QZ Fitness for Android

★★★★★ Han-Wei Lee · May 3, 2026

Fantastic app great bridge between treadmill and zwift, heaps of settings. Support and responsiveness from Roberto is amazing!

★★★★★ Tony S · Nov 28, 2025

Works great on my Yahoo V5 with Swift click to add virtual gears. Roberto was super helpful and very quick answering questions I had.

★★★★★ Chris Owen · Aug 3, 2025

Great app - warning to Echelon owners. Wonderful app with outstanding support. This has allowed me to connect to Swift which has completely changed my fitness training. Please note that Echelon have recently updated their firmware. If you install that update via the Echelon app it will lock you into the Echelon system. So if you want to use Swift, My Whoosh or Rouvy (etc.) the best advice is to ditch the Echelon app asap! My Echelon bike (Ex3) is great but this move by them really sucks!

★☆☆☆☆ Chris Lukasek · Jan 15, 2026

App doesn't work with Echelon bike if bike firmware was ever updated. Of course, there's no way to know that ahead of time since it doesn't say this in the description. Asked for refund and creator said he couldn't do refunds, even though official Google documentation says the app developer provides refunds. Glad I was able to line this guy's pockets some more.

★☆☆☆☆ Daniel Mello · Jan 4, 2026

It doesn't work. The UI is ridiculously poor. The developer was super quick to harassing and patronize me for a poor review, but it's been days since I removed the review and requested support, and I haven't heard back from him yet.

★☆☆☆☆ Jean Rossi · Jun 20, 2026

Unfortunately could not add the GPX file successfully even though it said it was uploaded. It also didn't sync with the treadmill even though it said connected.
