This is a great product. Although not sure why suddenly it is appearing on HN. Version 2 worked well and Version 3 I find a bit more complex but still great. Above what they have on their website, there's various extra packs (stencils) [0] that you can install with Bootstrap elements and Android Material elements. Albeit that I find its better to keep to the sketchy UI as otherwise you focus too much on the details. [0]: http://nathanielw.github.io/pencil-stencils/
