User Reviews

Reviewers generally find KeyLinker easy to use for basic setup and calibration and note firmware updates can improve recognition. However, the app suffers from widespread Bluetooth connectivity and detection problems, a confusing UI, limited mapping features, privacy concerns, and lag or performance issues that hinge on firmware updates. Overall, it works inconsistently and is unreliable for many users, though some enjoy the firmware/calibration capabilities when it does connect.

Pros

Easy to use for basic setup and calibration when a device is detected.
Can update controller firmware from the app and recognize devices after updates.
Useful for calibrating sticks on third‑party controllers.
Offers basic customization options and some features work as advertised (e.g., Turbo).

Cons

Unreliable Bluetooth connectivity and device detection (pairing drops, blank/grey screens, inability to connect).
Confusing UI/UX with settings not saving, gear icon loading, and navigation issues (buttons hidden or hard to access).
Limited and inconsistent button mapping (e.g., M1/M2 not supported) and weak macro/overlay capabilities.
Privacy concerns and security worries raised by multiple users (possible data privacy risks, accounts alerts).
Performance issues and firmware dependence (lag with certain features like Amiibo; frequent firmware updates required).

(Nyxi Hyperion 3) You need to manually give the app nearby device permissions otherwise you won't be connecting anything, it does not automatically request this permission. Once this permission is granted, press A on the right joycon to turn it on and it will appear as detected in the app, tap it to pair. The same is done with the left but I pressed left on the dpad to turn it on for detection. Nowhere in the app or device manual does it explain how to connect it to the app.
