The UI was clearly created by engineers, with no information designer involved. Try figuring out how to set a preset for your PEQ for each headphone. Good luck! Documentation does not provide a coherent answer this basic feature, or is not updated correctly. Unacceptable. ### 5/5 — Learning Curve but worth it *2026-02-16, version 3.1.7* The EQ provides amazing results. It can make any IEM sound much better. And in some cases it can make good IEMs sound incredible. ### 5/5 — The great app, and even better developers *2025-10-31, version 3.1.7* Super long term support. I can’t believe they updated the app for the new design language. Only app I’ve seen actually do it. NO bugs. Runs well. No crashes. It’s a good app ### 1/5 — Wont recognize any Bluetooth devices *2025-10-11, version 3.1.7* I Followed the setup instructions to the t. Once that didn’t work I did the same with the troubleshooting instructions. Would not recognize my headphones or earbuds. App is useless if you can’t connect a device to it. ### 1/5 — Doesn’t work on iPhone 15 *2025-10-10, version 3.1.7* Read all instructions, will not connect in app. 0 stars ### 1/5 — Russian/Korean Spyware *2025-09-16, version 3.1.6* Check for yourself… ### 4/5 — Works fine on MacOS Sequoia *2025-05-31, version 3.1.6* Great control app for Quedelix 5K, works fine on MacOS. Developers, it sure would be nice to have a Firefox or Safari extension. ### 5/5 — All the parameters! *2025-03-21, version 3.1.6* I really can’t say enough good things about this app or the device that it supports. No other portable DAC that I’ve come across offers the same amount of control and flexibility via an app, and the Qudelix itself sounds and works great. ### 5/5 — Absolutely perfect *2024-11-22, version 3.0.8* I bought the qudelix 5k originally feeling somewhat skeptical but it has went above and beyond my expectations, the app is incredibly functional that gives me full control over even the littlest part of the amp, the app is smooth and bug free. I would prefer a slightly nicer ui but as it is, it’s almost perfect ## Frequently asked questions about Qudelix ### What does the Qudelix app do?
