Comments on ctrl4U for Android

★★★★☆ Aiman Dossou · Feb 13, 2026

It would be truly perfect if you could make the scrolling mode smoother and/or make it possible to adjust its speed within the app. I primarily use this mouse ring to scroll through my webtoons and these changes would greatly enhance my experience. Thanks a lot for making this handy product!

Wrong description. This app is for a ring "mouse" controller for phone & tablet. OnCtrl ring control device. Whether it works or not, don't know yet.
