It's just the best app for bringing smooth scrolling to mac. When I was using windows and Linux in the browser, I had smooth scrolling, but once I started using mac with my mouse it was very uncomfortable. This app not just brings smooth scrolling to the mac, it does it better that windows and Linux as smooth scrolling works in every app not just the browser. The app is very simple doesn't really bother you and after install it works as intended across entire system. Summarized, I can say with confidence, this is the best implementation of smooth scrolling not just for mac but across every system.
