Chrono isn't just another speed controller. It is a powerful productivity dashboard designed for students, professionals, and anyone who values their time. Whether you are speeding through a 2-hour lecture or binge-watching a playlist, Chrono calculates exactly when you will finish based on your current speed.
🚀 WHY CHRONO? Most extensions just change speed. Chrono helps you manage it. We combined a precision speed controller with a retro-style Flip Clock and intelligent time estimation logic to help you fit more content into your day.

Its great! Being able to adjust the playback speed of videos can be incredibly helpful in managing your time and productivity. It allows you to: - Speed up through sections that are less relevant or slower-paced - Slow down complex or important parts to better understand the content - Fit more learning or viewing into your schedule you can take advantage of it to optimize your video-watching experience!
