For a long time, I've been searching for good wireframe / low-poly / prototyping tool and used mostly the Evolus Pencil before. Tried a lot of different products and was surprised that didn't found this one on PH. There is a lot of those in the business, but version 2 of this looks quite cool. They have good looking base mock elements, flexible pricing and overall good experience. I like the way of drag N drop of the product because I am not a designer myself, so creating images in 3rd party software and importing into other products is overkill for me.
