About Lock.in

The ultimate study app. This app lets you summon Subway Surfers gameplay overlay on any website to help you stay focused. Just click the extension button or click Ctrl + Shift + L to toggle the gameplay on/off while you study, code, or grind through lectures. It’s a lightweight, distraction-friendly background companion that gives your brain something to “idle on” without pulling you away from your work. Use it when you need a focus boost, a break, or a fun way to make long sessions feel less heavy. Move it wherever you want on your screen to find the optimal spot for your work. Note: This is a fan-made productivity overlay and is not affiliated with the official Subway Surfers brand.
