We love us some mock-ups! A prototyping tool helps a designer to weave visuals, navigations, and interactions altogether. They’re an essential tool in any UI/UX designer’s belt. Proto.io is a web-based tool that comes with a bucketload of add-ons and features. Easy importing of Sketch and Photoshop files, VR prototyping, UI Libraries, and a whole lotta testing tools. They also have templates to get you started!
