Easy to create complex animations and interactions

It's great for mocking up effects like animations, transitions without the issues of a very heavy program like after effects. I think performance wise, Flinto is great and allows me to incorporate animations and effects into my designs without affecting the overall performance on my system.

Flinto allows you to prototype workflows on digital applications seamlessly. It integrates with Sketch, so all your artboards are linked up automagically and you can start prototyping animations, tranistions, and click-paths. It speeds up the design iteration process tremendously.
