Umbra - Free focus app for Windows block distractions, stay on task

Built this because I wanted something like Cold Turkey Blocker but free and without the paywalled features. Started as a simple app blocker and grew from there - pomodoro sessions, schedules, a hard mode for when I actually need to be forced to stay off stuff, ambient sounds since I always have something playing in the background anyway, and stats to see if I'm actually sticking to it. Still actively working on it, so if you try it and something's broken or missing, let me know.
