Dayjavu

A 1 Second Everyday App for People Who Forget to Film

The idea is wonderful. The daily discipline is where it falls apart. If you have started a one-second-everyday project more than once and abandoned it more than once, the problem was never you. It was the requirement to remember, every single day, forever.

The streak is the wrong mechanic

Apps built around daily capture turn a memory project into an obligation. One missed day becomes three, three becomes a month, and the archive you wanted is now a reminder of something you quit.

Dayjavu removes the streak entirely. There is nothing to keep up, because the source material is footage you already shot for ordinary reasons: a dinner, a walk, a kid doing something briefly hilarious.

Retroactive by design

Point Dayjavu at a date range and it scans your library for every day that contains video. A calendar fills in, month by month, showing you a year you did not realise you had already documented.

From there it is selection rather than creation: pick the clip for each day, set where the second starts, and export. The work is an evening, not a year.

What you keep from the original idea

The rhythm survives intact. One day, one clip, a fixed length, in chronological order: that is what gives the format its particular emotional weight, and none of it depends on filming to a schedule.

How it differs

  • No streak, no daily reminder, nothing to fall behind on.
  • Works on years that have already happened.
  • Import a whole date range in one pass.
  • On-device processing, no account required.

FAQ

Can I import a year I already lived?
That is the main use case. Choose any date range and Dayjavu finds every day in it that has video.
Do I have to use one second per day?
No. One to five seconds per day, applied consistently across the compilation.
Is my library uploaded anywhere?
No. Dayjavu reads and renders locally on your iPhone. There are no servers involved.
