Impulse vs Pop: What are the differences?
Developers describe Impulse as "Dynamic JS Animations for the Mobile Web". Create animations that flow naturally from the user's movements. Rather than animating properties for a set amount of time, impulse takes a start position, end position, and velocity. On the other hand, Pop is detailed as "The extensible iOS and OS X animation library behind Facebook's Paper". Pop is an extensible animation engine for iOS and OS X. In addition to basic static animations, it supports spring and decay dynamic animations, making it useful for building realistic, physics-based interactions. The API allows quick integration with existing Objective-C codebases and enables the animation of any property on any object. It's a mature and well-tested framework that drives all the animations and transitions in Paper.
Impulse and Pop belong to "Mobile Prototyping & Interaction Design Tools" category of the tech stack.
Impulse and Pop are both open source tools. Pop with 19.7K GitHub stars and 2.9K forks on GitHub appears to be more popular than Impulse with 1.63K GitHub stars and 77 GitHub forks.
