I built a Sudoku app to help practice and learn advanced solving strategies. It's a progressive web app that can be used completely offline. Written in Angular with a Material UI.

Drop in on the release party live on Twitch at https://www.twitch.tv/ersimont. It's happening now until 9:30pm EST December 29th. Ask me anything here or in the live stream about how it's made, or why the world needed another Sudoku app.
