How long have you been together? Days of Us counts it on a split-flap board, like the ones at old train stations: days, weeks, months, hours, minutes, even seconds. It remembers every special day for you (monthiversaries, every 100 days, anniversaries, birthdays, and fun ones like a million minutes) and tells you the day before the big ones. Widgets put your count on your Home Screen and Lock Screen, every milestone becomes a card worth sharing, and one link sets up the same counter on your partner’s phone. Keep your firsts and favorite moments in a timeline, count down to the next time you see each other, and pick from ten hand-made looks. No account, no ads, no tracking: your story stays on your phone.
