Care Moments

Why fixed break timers stop working after a week

Interval reminders are a great idea that most of us quietly switch off. Here is why that happens, and what a rhythm-aware nudge does differently.

Almost everyone has tried it: a reminder every 25, 30 or 60 minutes to stand up, drink water or look away from the screen. The first few days feel virtuous. By the second week, the reminder has become something you dismiss without reading.

The clock doesn't know your day

A fixed timer treats every half hour the same. It interrupts you in the middle of a difficult paragraph, and it fires again ten minutes after you came back from lunch. When a reminder is wrong often enough, ignoring it becomes a habit.

Timing from rhythm instead

Jambu looks at the shape of your sessions — how long you've been active, when you went idle, what time it is, and the active domain. From those signals it learns what a normal stretch looks like for you, and offers a Care Moment when a stretch runs long, ideally at a natural pause.

  • Fewer nudges, because quiet stretches that are going well are left alone.
  • Better moments, because it waits for a gap instead of cutting in.
  • No escalation: ignore a Care Moment and nothing gets louder.

Timers aren't wrong — for some people they're perfect. But if yours has gone quiet in the background, it may simply be arriving at the wrong times.
