How it works

  1. 01

    Add what matters

    Give it a name and the next date.

  2. 02

    Tell us if it happens again

    If it repeats, choose how often.

  3. 03

    Know when it’s coming

    It appears in What’s Due when it enters your reminder window.

  4. 04

    Mark it done

    If it repeats, we calculate the next date automatically.

Dates, not documents.

Know What’s Due doesn’t need passport scans, licence numbers, account numbers, or anything else printed on the document itself.

Just save what you want to remember, when it’s due, and how often it happens. That’s enough to know when it needs your attention.
