Last week I asked for a chess app with local multiplayer and Chromecast support. /u/riskcheck linked me this app that is open source and fits the bill.
Now that I've had the chance to use it for the past week, just wanted to plug it here as I can say it works well and I appreciate the dev open sourcing the code and the lack of intrusive permissions and lack of ads.
