Thousands of videos.Watched once.

02How it works

Three taps.A whole year.

No filming every day, no editing skills. Dayjavu works with the videos you already have.

  1. 01 — 03

    Pick a day

    Your calendar shows every day you filmed something. Tap one, or let Quick Import fill a whole date range for you.

  2. 02 — 03

    Pick your second

    Scrub to the moment that says it all. One to five seconds per day, your call.

  3. 03 — 03

    Press play

    Every day, back to back. Your year becomes a film you can keep, export and share.

03The payoff

Scroll to play the year. One second a day.

365 days.About 6 minutes.

At one second a day, a whole year plays back in about six minutes. Short enough to rewatch. Long enough to feel it.

Streaks and stats

The REC line keeps count of your streak. Stats show your longest run, your months, and the weekdays you film or skip.

PAUSE 00:00:17

Plays like a tape

Scrub the filmstrip, tap an edge for the next day, hold to pause. Stop, and the frame turns into VHS tape.

Filmed on this date last year? It shows up faintly in today's square, and one tap plays the week around it. A reminder tells you too.

07FAQ

Questions? Answered

Everything you need to know before you start.

Do I need to film every day?

No. Dayjavu works with videos you already have in your library. Just pick a date range and choose your clips.

Does Dayjavu upload my videos?

No. Everything happens on your device. No cloud uploads, no data collection.

What happens if I lose or change my phone?

Save a backup from Settings, to iCloud Drive for example. The file holds your whole diary: which second of which video you picked for each day. Restore it on the new phone and Dayjavu finds each video again by its date and length. The videos themselves stay in your Photos library.

How long does a year recap take?

At one second a day, a full year plays in about six minutes. Pick longer clips (up to five seconds a day) for a longer film.

What is On this day?

If you filmed on today's date in an earlier year, Dayjavu shows that day's frame, faintly, in today's square on your calendar. Tap it to watch the week around it, or film today. A reminder can tell you too.

Can I share just this month, or a Story?

Yes. When you export, choose all days, this year, this month, the last 30 days or the last 7 days, then a full video, a Reel (9:16, up to 90 seconds), a Story (9:16, up to 15 seconds) or a square post. If the range is too long for the format, days are picked evenly so the video still spans the whole period. These presets are free.

Can I create multiple compilations?

Yes, with the one-time purchase. The free version covers a single compilation with as many days as you like, which is enough to see whether the format suits you.

What is free, and what costs money?

The whole workflow is free: import by date range, pick a clip for each day, and export in every format, from a full video to a Story. The free version covers one compilation with as many days as you like and clips of one or two seconds; exports keep the newest 12 days and carry a watermark. A one-time purchase, not a subscription, lifts all four limits and unlocks 4K export.

Your year is already filmed.Now watch it.

No filming required. Pick one to five seconds from each day and Dayjavu turns the videos you already have into something you'll actually rewatch.

Free to download. A one-time purchase exports every day and unlocks unlimited compilations.
