Seven minutes for one more short block
Seven minutes is 420 seconds. People pick it when they have a gap that is slightly longer than a five minute break, such as the time before a call starts, a brief read-through of a document before a meeting, or a seven minute presentation slot in a student showcase.
A seven minute slot is also handy for a rotating exercise in a class. Set it, let the groups work, and let the bell tell you to switch. The "Ends at" line shows the exact clock time, which helps when you need to announce when everyone should be back.
Controls are Space to start and pause, R to reset and F for full screen. The page keeps working in a background tab, and the title shows the time left. Copy link stores your sound choice if you run the same session on a second device.
Seven minutes is a good length for a first draft of a short note, a quick sketch, or a first pass at a worksheet. People also choose odd lengths like this on purpose, because a number that is not round feels more like a real deadline than a neat ten.
