Axure is a great tool and you can download and use it for a set number of days however purchasing the license can be expensive for some especially those starting their career. I’ve done a bit of searching and the aside from illustrator and even powerpoint which I find strangely adequate is a product called: SKETCH
http://www.bohemiancoding.com/sketch/
Easy to use and comprehend, sketch pretty much does everything that I need in terms of laying out visuals. You can move elements around, color code them and even integrate a template module.
- simplicity and versatility – 5 stars
- price point ($99) – 4 stars (much better than axure)
