The developer support is 2nd to none and Roberto will help you set it up exactly as you require. ### 5/5 — This app is great! *2026-08-11, version 2.20* I bought an Echelon EX-15 used on Facebook marketplace, and didn’t want to pay for their app. After some research online, I found a few people mentioning this app, and thought it was worth a try. I had some minor trouble setting it up, but it was because all my Bluetooth permissions weren’t enabled. Once I fixed that, I was up and running in no time. The little dashboard is so easy to use and gives me all the details I want. I never write reviews, but am just so happy with this app I wanted to let others know how great it is! ### 5/5 — Excellent app and support *2026-08-07, version 2.20* A great app to allow me to use my peloton with other apps such as Mywhoosh. When I struggled to get it to work, the support was instant and got it working straight away. Fantastic work thanks ### 1/5 — Doesn’t connect *2026-07-29, version 2.20* Brand new burdock track treadmill and it won’t connect…kept connecting to our tv and refusing to connect to anything else. ### 5/5 — Superb *2026-07-25, version 2.20* Game changer - enabled automatic incline sync from Zwift to my Horizon treadmill. Super easy to set up - everything connected seamlessly (treadmill + heart rate monitor) & immediately recognised by Zwift. Took 5 minutes to set up compared to about 1 hour trying to connect the treadmill / Zwift without this app. ### 5/5 — Great Customer support *2026-07-23, version 2.20* Had issues with the app, wasn’t complicated and got instructions to fix and the app works as advertised. ### 5/5 — Fixed *2026-07-09, version 2.20* The developer was great and helped me fix the issue! ### 5/5 — Must have app! *2026-07-06, version 2.20* This app is amazing for anyone wanting to get the most out of their fitness equipment! Don’t get me wrong, takes a while to get used to it but once you’ve had a look at what works for you and ensured the tiles you prefer are what’s shown, it’s great! Support is also fab and any issues or questions are dealt with straight away! ### 5/5 — Works extremely well. *2026-07-01, version 2.20* Excellent app, excellent support. ### 5/5 — Amazing unblocker! *2026-06-20, version 2.20* Very grateful this exists, the settings looked a little complex at first as it covers lots of hardware but it works really well and I didn’t have to actually do that much tinkering to get my set up going great. Roberto also replied to my questions very quickly and is a total gem! Worth every penny ## Frequently asked questions about QZ ### What does the QZ app do? The QZ app acts as a bridge, allowing you to connect your compatible home exercise bike, treadmill, elliptical, or rower to popular virtual fitness platforms like Zwift, Peloton, Fulgaz, and Rouvy. It essentially gives your existing equipment a second life by enabling it to be recognized by these training apps. ### What exercise equipment is compatible with QZ? The app supports a wide range of equipment, including many Echelon bikes and rowers, Domyos bikes, treadmills, and ellipticals, as well as Proform bikes and treadmills, Concept Rower 2, and several other brands. Specific compatibility details and firmware checks are available on the developer's website. ### How does the app handle heart rate monitoring? QZ can integrate with HealthKit to read your heart rate directly from your Apple Watch or any Bluetooth heart rate belt. This heart rate data is then saved within your workout logs, providing a more comprehensive record of your training sessions. ### Is the QZ app free to use? The app is free to download and use for its core functionality of connecting your equipment. However, there is an optional auto-renewing subscription called the 'Swag Bag' available through an in-app purchase to support the app's development. ### Can I use this app with my existing exercise bike and Zwift? Yes, if you have a compatible exercise bike (such as Echelon, Proform, or Domyos) and want to use it with Zwift, this app is designed for that purpose. It allows Zwift to recognize your bike's performance metrics, enabling you to participate in virtual rides. ## Version history (last 5 releases) ### 2.20 — 2026-03-24 - Garmin Connect Integration added - Peloton Walking Treadmill classes handled and API improvements - Wifi support for Rouvy and Mywhoosh - Intervals.icu integration added - Workout editor added - Workout history added - Voiceover added - Air Pods Pro 3 Heart rate support - Mywhoosh Rower compatibility added - Automatic virtual shifting - Peloton auto sync improved - Apple health without Apple watch - Live Activities - Elevation on apple health for treadmills - ERG mode improved for device that doesn't have ERG mode implemented - Technogym Ride supported ### 2.19 — 2025-07-09 - Peloton rides fixed - proform treadmill 995i added - proform carbon tls added - Start and stop icon in the 3d map - fix for Concept PM5 Rower - BODY Bike Smart+ integration - Apple watch integration crash fixed - Kingsmith treadmill Runna integration - Kinetic trainer control added ### 2.18 — 2025-06-11 - new peloton login - zwift play over dircon - tacx improvement - core sensor supported - a lot of new devices supported! ### 2.17 — 2024-10-14 Auto Inclination on Zwift for all the treadmills Zwift Ride compatibility added with virtual gears to all the platforms (Zwift, Indievelo, Rouvy and Mywhoosh) ### 2.15 — 2023-08-09 iOS12 crash fixed! ## Apps similar to QZ | App | Rating | Price | Category | | --- | --- | --- | --- | | [Stryd](https://appshunter.io/ios/app/stryd/id938379154) | 3.9 (239) | Free | Sports | | [ROUVY Companion App](https://appshunter.io/ios/app/rouvy-companion-app/id1585185144) | 2.5 (48) | Free | Sports | | [ROUVY: Real Indoor Cycling App](https://appshunter.io/ios/app/rouvy-real-indoor-cycling-app/id1478239111) | 3.8 (518) | Free | Sports | | [MyWhoosh Link](https://appshunter.io/ios/app/mywhoosh-link/id1561724525) | 2.2 (33) | Free | Sports | | [Canyon](https://appshunter.io/ios/app/canyon/id6443914990) | 4.8 (2,451) | Free | Sports | | [Running & gait analysis - Ochy](https://appshunter.io/ios/app/running-and-gait-analysis-ochy/id1531481638) | 4.5 (283) | Free | Sports | ## More apps by Roberto Viola - [ARadar](https://appshunter.io/ios/app/aradar/id1625452581) - [Ultratrack](https://appshunter.io/ios/app/ultratrack/id6443868636) - [Greppy](https://appshunter.io/ios/app/greppy/id6477757109) - [ClimbTracker Watch App](https://appshunter.io/ios/app/climbtracker-watch-app/id6479173765) All apps by Roberto Viola: https://appshunter.io/developer/951920407 ## Related topics [qz zwift](https://appshunter.io/ios/topics/qz-zwift) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
