I was searching for a good study timer with ambient videos, Spotify, and nice themes. Everything online was either trash or behind a paywall. So I built Hourglass — completely free. Features: ✦ Ambient video backgrounds (café, rain, forest, Tokyo, train, fireplace) ✦ Spotify playlists for each vibe ✦ Pomodoro, Deep Focus, 52/17, Ultradian, custom timers ✦ No login, no ads, no premium tier hourglass-study.vercel.app
