In the pre-Figma days, we all used Sketch. At the time, Sketch lacked prototyping features like navigating between boards and scrolling.
I built a Sketch plugin that allowed you to add interactivity and preview your designs live on your mobile device.

Mirr.io was used extensively at Meta's TTC Labs Design Jams to bring ideas to life during workshops around the world.


These days prototyping interaction is an extension of most designers' toolkit. Mirr.io was discontinued when Sketch and Figma began to offer these features natively.
