One second of video. Every day. Forever.
One Second Days is a quiet place to keep the smallest pieces of your days. Open it once, capture a single second, and let the year assemble itself. In twelve months you have a living film of your life. In ten years, a museum.
CAPTURE
Tap the shutter for exactly one second — the whole idea, and the reason it never becomes a chore. Hold it when a moment deserves more, up to five seconds. Past three the ring turns to embers, so you can feel that you're on borrowed time.
REMEMBER
• A timeline of every day you've kept, grouped by month
• A year mosaic where each day is one glowing frame, and the gaps are honest
• Notes and moods, if you want them — both optional, never nagged for
• A year ago today, waiting quietly on the home screen when there's something to find
MEMORY MOVIES
Render your seconds into a single cinematic film — by month, by year, by the ones you kept, or across everything you've ever collected. Real dissolves, a title card, your own sound, exported and ready to share.
QUIET BY DESIGN
One gentle reminder a day, at a time you choose. No streak shaming, no badges, no feed, and nobody else's days to measure yours against.
PRIVATE BY DEFAULT
There is no account and there are no servers. One Second Days makes no network requests at all — your clips, notes and moods live on your phone and nowhere else. No analytics, no advertising, no tracking, no third-party SDKs of any kind.
A single purchase. No subscriptions, no in-app purchases, no ads.
One second can hold a lifetime.
