Persistent reminders

A reminder app that follows up without piling on guilt

Duqo checks back when a one-time alert was not enough, while respecting quiet hours, your calendar, and a daily reminder cap.

Persistence should mean another useful chance to act—not the same notification repeated until you mute it.

Why it matters

A reminder has to survive real life

One alert is easy to lose

A notification can arrive while you are driving, presenting, or simply focused elsewhere. Dismissing it does not mean the task stopped mattering.

More noise is not the answer

Duqo spaces follow-ups around the day instead of turning every unfinished task into a stream of identical alerts.

Your chosen time still matters

Times you explicitly set take priority over automatic scheduling, quiet hours, and the daily cap.

How Duqo helps

From capture to a usable follow-up

  1. 1

    Capture the task naturally

    Type it, say it, or add it from a photo of a list.

  2. 2

    Duqo looks for usable moments

    Connected calendar context and quiet hours help avoid meetings and sleep.

  3. 3

    It checks back

    If the task remains open, Duqo can follow up later rather than treating the first alert as the end of the story.

Clear limits

What Duqo does not promise

  • No reminder system can guarantee task completion.
  • Calendar-aware timing requires calendar access; you can use Duqo without connecting one.
  • Lock-screen alarms require iOS 26 or later and are not available in the browser.

Does Duqo keep notifying me forever?

Can I set an exact reminder time?

Yes. A time you choose yourself is preserved rather than moved by automatic timing rules.
