#ブラウンノイズ

#ポモドーロ

On the other hand, I created this for people who say "I can actually concentrate better when there's sound~" as something that extends brown noise a bit. Rather than balancing concentration and breaks, I've given it the role of stopping hyperfocus. It's kind of the opposite of existing Pomodoro timers.
