What a 30 minute timer is good for

  • Study blocks and exam practice sections.
  • Cooking and baking: casseroles, cakes and rice dishes.
  • Screen time limits for games and videos.

Accurate in the background

The countdown is measured against your device's clock, not by counting ticks, so 30 minutes is exactly 30 minutes even when you switch to another tab. The time left also shows in the tab title. On phones, keep the screen on so the alarm can play.
