What does the “clock” symbol do?

What does the “clock” symbol do? It appears to make the session go by quicker? Is that correct?


What the clock does is keep in the pile the reviews that are half-completed. For example, imagine you need to stop doing reviews for some reason, and you can’t finish them all. You click on the clock, and it makes sure that no review stays half-done (for example, just with meaning done), so that you stop :slight_smile:
