A video diary that keeps just 3 seconds of your day. Record and you’re done — no editing. Now and then, a special effect turns a reel into a memory from long ago.
AYU3 is a 3-second video diary with no editing required.
Capture just three seconds of a moment, and watch the ordinary days of your life slowly become a film.
Your kids growing up, life with your pets, a trip, an ordinary today — kept just for you.
■ Keep today, in just 3 seconds
Press the record button and it captures exactly 3 seconds, then saves itself.
You don't have to keep much. No editing, no save button.
Record, and you're done.
Five clips a day. That's the limit.
Because there's a limit, the ordinary moments get chosen —
and a missed day is never held against you.
■ You won't know until you watch
Each clip is finished automatically to match its light and time of day.
A night walk home, a sunlit noon, a sudden sepia —
the same everyday life, kept in slightly different faces.
■ Videos become a diary
The date appears large when you play a clip, making each video a diary page.
Only the days you recorded carry amber dots on the calendar.
Pick a day to play it in one piece.
Play a whole month, and it becomes your own short film.
■ Every day, a little film
Stitching them together is the app's job.
Record on three days, and your first little film appears by itself.
Export it as a single video and share it anywhere.
Now and then, a special effect settles on a reel, and it feels like a memory from long ago: a "Distant Memory".
■ AYU3 Plus (one-time purchase)
Some days, you want to keep more. Plus is for those days — pay once, keep it forever.
- Up to 10 clips a day (your usual 5, then 5 more with Plus)
- Change the finish afterwards — or set it back to automatic
- Reels for any date range you like
Not a subscription. Family Sharing supported.
Free stays free, forever.
■ Privacy
Your recordings stay on your device and in your own iCloud (backup is optional). No accounts, no servers.
No data collection of any kind.
■ For people who
- never make it past day three of a written diary
- want to keep the ordinary days of their kids or pets
- want to keep everyday life for themselves, not for social media
Today's 3 seconds can only be recorded today.
Even an ordinary today will someday be a treasured memory.
Walking through life, 3 seconds at a time. AYU3
Ratings & Reviews
This app hasn’t received enough ratings or reviews to display an overview.
Looking back now feels like an album
• On Home, each reel is a card with three prints — the first, middle and last moments — and a date tape, so you can see what's inside at a glance. Slide sideways for the next reel.
• "Distant Memory" reels arrive with their prints already painted.
• Thumbnails in Timeline and Recent now have a photo-print border.
Gestures
• Swipe left on Home for Timeline, right for Settings.
• Pull Home down to reveal the camera waiting behind it. Swipe up on the camera to close it (never while recording).
Appearance
• Settings > Appearance now offers Light and Match iPhone. Only the colors change; the camera screen stays dark.
Also
• Reels now show the dates they span instead of "clips / days / seconds".
• Counts and reels refresh when the date changes while the app is open, or when you come back the next morning.
