Nerd Squirrel
A cozy pomodoro timer with a study buddy who focuses with you.
Pick a task, press Start, and your squirrel puts on its headphones and studies by your side. Focus for 25 minutes, take a 5-minute break, repeat. Leave the app to scroll and your squirrel notices, and gets a little worried.

What's inside.
