Show the countdown numbers when an exact remaining duration matters. Hide them when you prefer to follow the liquid proportion, and choose filling or draining mode in Settings.

Try those options on a short routine task and check whether the ending is understood. These are interface choices, not findings from a user study or a guarantee of reduced mental effort.

Our Liquid Countdown Timer is an application of these HCI principles. By making time perception effortless, we allow you to focus more deeply and for longer periods without the mental drain of constant clock-watching.
