Your days together,
on your Lock Screen.
No account. No subscription. Nothing leaves your phone.
In Chinese legend, the Old Man under the Moon ties an invisible red thread between two people who are meant to find each other. It can stretch, it can tangle — it never breaks.
Red Knot counts the days since you tied yours: Day 1, Day 100, Day 1,000. Quietly, beautifully, on your Lock Screen and Home Screen.
