You set a hydration reminder for 10:00 every morning. For the first week it works great. By week three, the Telegram ping barely registers. You dismiss it on autopilot and forget to actually drink the water.
This is alarm fatigue — your brain's predictive machinery learns the exact timing and pre-emptively tunes out the signal before it even arrives. It's the same reason you stop noticing the hum of your air conditioner.
The fix: randomness within a range
Random-window reminders fire at a different time within a defined window each occurrence. Instead of always at 10:00, Whisp might ping you at 9:47 today, 10:22 tomorrow, and 10:03 the day after — all within a 9:30–10:30 window you define.
Because you can't predict the exact moment, your brain can't pre-tune it out. The reminder lands with the same cognitive weight it did on day one.
What it's good for
- Hydration — drink water "sometime mid-morning" not "at exactly 10:00"
- Posture / stretch breaks — a randomised prompt every 60–90 minutes throughout the work day
- Mindfulness — a pause-and-breathe prompt that doesn't feel mechanical
- Review habits — a daily "check your inbox" or "review your notes" that stays surprising
How to set one in Whisp
In the web dashboard, create a reminder and choose Random window as the schedule type. Set your start and end times and pick the days you want it active. Whisp picks a fresh random time within that window for each occurrence.
You can also set multiple random windows in a single reminder — for example, one mid-morning and one mid-afternoon — to get natural-feeling prompts throughout the day without mechanical precision.
Give it a week. Your habits will thank you.
