Small moments, kept close
A laugh, a view, an everyday detail. One second gives each day its place in your story.
1 Private second a day
A second a day.
A story only you own.
Keep one photo or one second of video a day. Revisit past years. Turn your memories into a movie. No ads. No tracking.
02 / Private
Private from the start
Your diary is stored on your iPhone, without an account or a cloud service. You choose when to export or share it.
03 / Free to begin
Free to begin. No subscription.
Keep daily moments for free. Upgrade once for more projects, higher-resolution movies, no watermark and Face ID lock.
ONE SECOND, YOUR CHOICE
Keep the part that matters.
Choose a photo or video. Frame your photo or pick the exact second. Videos keep their audio when available; photos become silent one-second clips.
Add past days and previous years whenever you like.
