Lo-fi Wireframe Announcement Modal Pop-up

Wanting to show more of my design process. I'm working on redesigning the web application for www.twibble.io and am starting from the beginning.

Starting to build out the application in lo-fi wireframes and determine the flow.

🤔 Design Question
Using Sketch, but wondered what people use to show application flow / sitemap? Would love to know what tools you use!

Stay tuned for more of my design process and the redesign of Twibble.
