Scene motionRain, snow and embers drift on one light canvas. Off makes every scene a still painting.

Study timer FAQ

Is 25 minutes a good study timer length?
Yes. Twenty-five minutes is long enough to make progress and short enough to stay focused. If you need more time, try 30, 45, or 60 minute sessions.
Should I take breaks between study timers?
A 5 minute break after a 25 minute study timer is a good default. For longer sessions, take a longer break every few rounds.
Can I use this for homework on mobile?
Yes. The study timer works in mobile browsers, so you can keep it open beside notes, books, or a laptop.
