Open, they're apart. Close, they're together. Two little ones stand on either side of your screen, with a fold between them. Close your phone a little, and they come a little closer: a step, a pause, a glance away. Close it all the way, and they meet in the middle. Open it again, and they drift apart. That's all that happens. They don't speak, and they don't come with a backstory. Whoever comes to mind while you watch them — that's the story. # CLOSER, BY YOUR HAND On iPhone Duo, the fold does it: close your phone slowly and they come together. Stand it up on the table and it becomes a small stage. On iPhone and iPad, draw one of them towards the middle with your finger. # THE SAME MEETING, TOLD DIFFERENTLY Soft and round, shadows on a lantern screen, a dot and a line, or two porcelain figures on a turning stand. Different pairs, different stories: some shy, some that walk right past before turning back. And two cats who can't meet without a full and frank exchange of views. How it ends, they'd rather not say. # WORDS AND DAYS Give them names, and a few quiet words they'll say when they meet. Pick a day worth counting, from the day something began or down to the day you'll next be together, and keep it on your Home Screen or Lock Screen. It moves on by one each midnight. # A MOMENT TO SEND When they meet, keep that moment as a short video and send it to someone. # SMALL THINGS A heartbeat you feel in your hand, quickening as they draw near. Quiet music for each look. And On Their Own: leave them be for a while and they'll wander together and apart by themselves. # PRIVATE BY DESIGN No sign-in, no account, no analytics, no ads. Names, words and days stay on your device. # FREE TO START The whole meeting is yours: the soft round look, the shy first story and the two of you, with names, music, the heartbeat, On Their Own and a video to send. # LINGER PREMIUM • Every look, every story and every pair • Every song, with any look • Quiet words and a day to count, on stage and on your Home Screen • Videos with just the two of them, nothing in the corner • New looks, pairs and stories as they come, all included Requires iOS 26 or later. Works on iPhone and iPad; designed for iPhone Duo. Open, they're apart. Close, they're together. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
