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 โ 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 โข Every look, every story and every pair โข Every song, with any look โข Quiet words and a day to count, on stage and on your Home Screen โข Videos with just the two of them, nothing in the corner โข 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/

Verdict
The clearest difference is in-app purchases: BTK 360 at none against Linger's 3. BTK 360 also leads on iOS requirement (15.0 vs 26.0). Linger's advantage is update cadence (every 4 days vs every 9 days). On price, ads and device support there is nothing between them.
