Stencil

I've used Canva for my designs previously, but Stencil does it all nearly as well as Canva, plus it has a great Wordpress plugin which saves by allowing me to add new designs without leaving the WP dashboard. Great!
I like all those icons and background that are available by default. Previously I had to search for icons in the internet, now there's a huge pack included in Stencil. Another time-gaining feature.
It's worth investing in tools that save you time. That's precious!
