Quick answers
Is 20 minutes good for studying?
It's a popular length: long enough for one section, short enough to stay sharp. Test yourself from memory at the end.
What if I lose focus halfway?
Notice it, then come back to the task. The timer keeps running, and coming back is part of focusing, not a failure. See getting back on track.
Does the timer keep running if I switch tabs?
Yes. It counts from the clock, not from the screen, so it stays accurate in the background, and the tab title shows the time left. Nothing is sent anywhere.
