Guide

Guide (read in ~3 minutes)

90 seconds is perfect for micro‑starts: breathing, plank holds, quick resets, or a tiny push to break inertia.

Best for

  • 1 deep breath cycle
  • a single set / interval
  • close one distracting tab
  • write the first sentence

Quick setup

  1. Name one outcome (one sentence).
  2. Remove one distraction (close one tab, silence one notification).
  3. Press Start, then do the smallest next action for 60 seconds.
  4. When the timer ends, write the next step.

Principles (research-backed)

  • If–Then starting rule: Implementation intentions (“If X, then I do Y”) make starting dramatically easier. (study)
  • Reduce decisions: Procrastination is often an intention‑action gap — a timer reduces the decision load. (review)
  • Timebox the task: Timeboxing beats vague to‑dos because it creates a clean boundary. (principle)

Two quick mantras

Shrink the box until it feels safe. End with a 10‑second note: the next step.

FAQ

Does the timer start automatically?
Yes. When you tap “Start 1:30”, we open the timer with a preset and autostart enabled, so the countdown begins immediately. If you prefer manual starts, open the app and start from there.
What time formats do you support?
You can type durations (10m, 90s, 1h 10m) or clock formats like mm:ss (10:00) and hh:mm:ss (01:15:00). If you enter a plain number (e.g., 10), it’s treated as minutes. This keeps quick presets fast.
Can I go fullscreen?
Yes — press F for fullscreen and Esc to exit. Fullscreen is great for focus, classrooms, and cooking because you can see the time from across the room. On mobile, fullscreen depends on the browser.
How do I pause or reset?
Press Space to pause/resume. Reset requires two presses of R (or the Reset button twice) so you don’t wipe a session by accident. This is especially useful on touch devices.
How should I use this for time management?
Pick one micro‑outcome before you start (one sentence). Then timebox: for this block, you do only that — no switching. When the timer ends, write the next step so restarting later is frictionless.
Will ads interrupt the timer?
No. Ads are shown outside the running timer view so the countdown stays clean and readable. Fullscreen keeps the timer distraction‑free.
