Krumi — leave words where they happened, for the next person who walks by. Krumi is a place-anchored note app. Your words stay where you wrote them. Someone has to physically walk to that spot to read what you left. WHAT YOU CAN DO · Drop a note at your favorite café for the next person who sits there · Leave a story on a quiet street corner that only people walking by can hear · Mark a memory at a mountain peak, a beach, anywhere worth remembering · Find quiet encounters with strangers in your neighborhood, school, or office WHY KRUMI · Quiet — no follower counts, no public feed, no algorithmic push · Local — drop within 80m of the spot, read within 200m · Light — sign in with Apple or phone number, no profile setup required · Free — and we don't sell your data SAFETY Every user-generated note is moderated. Anyone can report or block in one tap. We commit to handling reports within 24 hours and have zero tolerance for hate, harassment, sexual content, or illegal material. If you also believe places remember things — leave the first Krumi.
