3 ideas coming back today

Every saved item — video, playlist, bookmark, or nugget — goes onto a fixed spaced-repetition ladder. When an item comes due, Recl brings it back as a recall card with its key ideas.

Read it, then tap Mark reviewed. There is nothing to grade: each review simply moves the item to the next, longer gap.

The schedule

  • 1st review → 1 day later.
  • 2nd → 3 days later.
  • 3rd → 7 days later.
  • 4th → 14 days later.
  • 5th → 30 days later.
  • 6th → 60 days later — then the item graduates and stops coming back.

Why fixed gaps

Each gap is a little longer than the last, so an idea comes back around the time it would otherwise fade. A fixed ladder keeps it effortless: no scoring, no decks to manage — just a quick look when something is due.
