A break reminder for Mac that doesn't nag

WISP: a light passing along one edge of a Mac screen

You turned on a break reminder once. It popped up, asked you to click something, and by the second week you had switched it off. Willpower had little to do with it. What wore you out was what the reminder asked of you every time it fired.

Why most reminders get turned off within a week

Look at what a typical reminder does. It interrupts: a window takes focus, sits on top of whatever you were doing, and waits. It counts: a streak, the number of breaks taken today, a percentage toward a goal. It judges: a red badge, a phrase like "you are overdue", a tally of skips. Any one of these turns the reminder into a small chore on top of the work it was supposed to protect you from.

The interval does not change this. A five-minute reminder and a ninety-minute reminder fail the same way, on different schedules. The fault sat elsewhere: the reminder demanded a response, a click or an acknowledgment, before it would go away and let you keep working.

The difference between a notification and a cue

A notification wants something from you. It queues up, waits for a click or a swipe, and until it gets one it sits there, sometimes on top of the last one you ignored. That is fine for a message you need to read. It is a poor fit for something that should happen every hour of every working day for months.

A cue shows up, is visible for a moment, and is gone whether or not you looked at it. Nothing depends on your response. If you notice it, you notice it. If you are in the middle of a sentence and miss it, it has already finished, and the next one comes at the same interval. The cue's job ends when it finishes displaying, not when you dismiss it.

A wall clock and an alarm make the same distinction. The clock is there if you glance at it and never demands that you do. An alarm insists. Most break reminders are built like alarms. The ones that survive months of daily use are built like clocks.

What a good interval cue looks like

A few properties separate a cue you will keep from one you will switch off:

Put those together and you have something that marks time passing at an interval you chose, and leaves what you do with that moment to you.

Where WISP fits

Callulu is a small Mac menu bar app with eight visual cues, and WISP is the one built for this. When it is on, a light passes along one edge of the screen (left, right, top, or bottom, your choice) for about a second, at an interval you set, anywhere from one minute to a whole day. There is an optional short sound; by default it is silent. The light draws over whatever is on screen, across every Space and over full-screen apps, and it is click-through, so clicks land in the app underneath.

In the menu, the word under WISP is Pause, and in practice it is a break timer you set from the menu bar. It marks the interval and moves on, and what you do with the moment is yours. Choosing WISP in the menu again turns it off, and the switch at the top of the menu stops every cue that is on.

Choosing an interval that you will keep

The interval that works is short enough to matter and long enough that you stop noticing it as an interruption. There is no single right number, but a few starting points help:

  1. If you have never used an interval cue before, start longer than you think you need, twenty-five or thirty minutes, and shorten it later if it feels too sparse.
  2. Pick an edge you are not already using for something else. If your Dock or a toolbar lives at the bottom, choose the top or a side.
  3. Leave the sound off for the first week. Add it only if you find you keep missing the light.
  4. If you catch yourself dreading it, the interval is wrong, not you. Widen it.
  5. Look at the choice again after a month. What suited a week of writing may not suit a week of meetings.

One interval, one edge, one week

Set one interval, pick one edge, and leave the sound off. Give it a week without changing anything, because the first few days are where most reminders get judged too early. If the light at the edge becomes something you expect rather than something you brace for, you have found the right interval. If not, widen it before you decide the whole idea does not work for you.
