Flowkit is a Sketch library that allows you to quickly build out high-level flows to tell the story of your designs—perfect for presentations and documentation. You have full control over intelligently-named symbols and endpoints, making complex flows a walk in the park.
With Anima 3.0 designers can create fully functional, responsive and interactive High-Fidelity prototypes, and it's all done inside Sketch.
You can then share prototypes, and collaborate by having team members and stakeholders actually experience your product designs, rather than tapping on static screenshots.
Overframe is a screen recording app that comes with phone frame for you to overlay on top of your app or prototype window. Get nice little video to share it around 👍
