Can’t say enough good things about this app. Firstly, it can integrate in so many different ways, and with so many devices, it’ll likely do whatever you need it to do. Personally, I needed an app that could connect to my indoor bike, grab all of its stats - speed, distance, cadence, watts, etc - and post them to Apple Health when my workouts ended. I also needed something that had an Apple Watch app so I could see those stats as I ride, and so that my rings would get closed properly. QZ does all of that perfectly and then some. But what I’ve been even more impressed by is the developer himself. I had tried so many different setups to accomplish what I was looking for, and none of them worked right, so before I had even downloaded the app I emailed him to see if QZ could do what I needed it to do. He responded to me within a few hours letting me know it could. Not only that, but as I’ve used the app we’ve corresponded about the various features and how they work, and within a few days he had made a couple of changes and added new settings based on my feedback. Unreal. If you’re looking for an app to help enhance your workout tracking - download QZ. Believe me, it’s worth it. 10/10
As an avid user of both the Peloton and Zwift apps, I've long sought a solution that seamlessly links my exercise bike to these platforms. Fortunately, I stumbled upon an absolute gem: an app that not only effortlessly connects my exercise bike to Peloton and Zwift but also comes with unparalleled customer support. The brilliance of this app lies in its simplicity and reliability. With just a few taps, I can sync my exercise bike to both Peloton and Zwift, and the bike I bought was only $300 (Echelon EX-3, I didn't eve need to spend over a thousand dollars on a peloton bike to get the full peloton experience!). Whether I'm chasing personal records in Zwift's virtual landscapes or engaging in Peloton's energizing classes, this app ensures a seamless transition between platforms, allowing me to focus solely on my fitness goals. What truly sets this app apart, however, is the exceptional support provided by its creator. Whenever I encounter an issue or have a question about setup or functionality, I simply post my question on the creator's website. Without fail, I always receive a response resolving the issue on the same day. This level of dedication and responsiveness is a testament to the creator's commitment to customer satisfaction and sets a standard for excellence in app support. It is no surprise that this app has all 5 star reviews, it is well deserved!
Updated review: I made a mistake and wanted to apologize. I didn’t know how the buymeacoffee website worked and thought it was a subscription contribution like patreon. It’s actually a one time fee, which I think is valid for the effort behind the app and the support given by the developer for free to whoever buys it. The app itself is great, especially with the newer functionalities that are being integrated, like 3D Maps for virtual GPX workouts, Zwift and QZ on the same iPad. I was wrong on my initial review and it wasn’t fair to the developer and to what the app delivers. Original review: The app itself is great, but the developer wants you to pay extra if you want newer functionalities, such as using QZ and Peloton on the same iPad, for example, on what he calls beta versions and takes a long time to release newer versions here in the app store (last one was more than 4 months ago). His words for me on the support community on Facebook were: “the $3,99 is not enough for all the development behind it” and “I will release a newer version in the app store when there is a major issue with the current version”. So unless you’re willing to buy the app here, then fund his development on Patreon monthly ($6) to have updates, think twice. Why not make the app more expensive instead so you know where you’re stepping into when you buy it? I appreciate the support and the app functionality as it is (definitely worth the 3.99 - I’d even pay more if it was more expensive), but I’m not adding another subscription to my already large list.
