Destimulate yourself.
radialtimers.com 是一个免费计时器网站，极简设计，为专注而生。时间被画成二十个同心圆环，随流逝一环环清空：一眼便知还剩多少，精确读数就在表盘下方。
希望这些计时器能派上许多用场，从功课到下厨。用 Google 登录后，你的总时长会跨设备保存，并让你登上排行榜，与这里所有计时的人一较高下。
Video export comes with a free account. Premium is the full bundle: 4K and 60 fps exports in vertical, square, transparent, and dark versions, your pick of penchick parade, the site’s papers and skies, long timers, and no ads anywhere. Every new account’s first week of premium is on us. Invite two friends and it is yours permanently, as a supporter. Students and educators keep it forever: sign in with a school address and it applies on its own.
