You already know how to doom-scroll. Now do it with purpose. Tomescroll turns the reflex you already have — that itch to swipe — into a habit that actually leaves you knowing things. Each card is a single fascinating fact, illustrated in pixel art, drawn from the vast strangeness of human knowledge. History, science, philosophy, nature, geography. One insight. One minute. The longer you explore, the smarter your feed becomes. One topic leads somewhere unexpected — fermentation science to ancient Mesopotamia to the chemistry of bread — and Tomescroll maps everywhere you've been and hints at everything you haven't found yet. No quizzes. No streaks. No pressure. Just the oldest human impulse: wondering what's next. Terms of Use: https://tomescroll.app/terms
