One swipe. One fact. One thing you'll actually remember.
Krum delivers surprising knowledge across 31 topics — from space anomalies to true crime cases. Free, forever.
Krum turns dead scrolling into something worth your time.
Instead of endless videos and outrage, you get one punchy fact per swipe — 20 to 30 words that actually stick. History, science, space, psychology, true crime, food, philosophy... 31 topics, one vertical feed.

WHAT MAKES KRUM DIFFERENT
Most learning apps want hours. Krum wants 60 seconds.
Every card is a single fact — sourced from real references and rewritten to be surprising, punchy, and immediately shareable. No lectures. No quizzes you didn't sign up for. No paywalls mid-session.
You swipe. You learn. You stop whenever you want. Either way you walked away knowing something you didn't before.

BUILT FOR THE CURIOUS
Krum is for people who read the Wikipedia sidebar when they're supposed to be doing something else. For the person who always ends up going down a rabbit hole. For anyone who wants the knowledge without the homework.
One fact. One swipe. See you tomorrow.
