what's the best app to draw UI wireframes on the mac? (And why) [closed]

I want to draw user interfaces for web and desktop applications.

I need something less print-oriented than omnigraffle. think pixels!

Also, need good building blocks (aka stencils). Form elements, tableviews, etc.

Does Canva have wireframes?

– Yes, you can wireframe in Canva! Canva offers a wide range of templates and easy-to-use tools that make creating a wireframe quick and easy.

I've been playing around with Balsamiq Mockups and it's OK for basic wireframes. I still prefer pen and paper sketches that are later refined in Photoshop when working on my own, but Balsamiq is useful when working in a team.

WireframeSketcher wireframing tool comes with fast and native UI on Mac. It works well with retina display too. There is a large built-in library of controls and extra stencils are available.
