Couverture lets you manage, edit and preview easing and spring curves. It’s great to experiment with thanks to the realtime preview. You can then export curves into the most common formats.

  1. Easing curves

    An easing function, also known as “timing function”, is used to specify the rate of change in an animation over time, influencing the speed or pace of the motion.

  2. Spring curves

    A spring curve is used to create a natural and dynamic motion, often associated with bouncing or overshooting effects.
