Frequently asked questions

What is a one-hour timer useful for?
An hour-long study or work session, a workout class, a parking or meter window, a cooking stage, or a timed exam section. It is the default planning unit for a reason.
Will it alert me if I am in another app?
The hour is timed accurately from the real end time, but a backgrounded tab can delay the alarm by up to a minute, and a closed tab will not alert you at all — there is no server behind it. Keep the tab open; on iPhone, keep the side mute switch off.

This timer keeps the exact time even if you switch tabs. If this tab or your browser closes, nothing can alert you at the exact finish time — there's no server behind this, by design. Come back any time and we'll tell you honestly how long ago it ended.
