⏱️ Stopwatch vs. Countdown Timer
A stopwatch and a countdown timer measure time in different ways. A stopwatch starts at zero and counts upward, making it useful when you want to know how long an activity takes.
A countdown timer starts from a selected amount of time and counts downward until it reaches zero. For example, you might use a countdown timer for a 10-minute break, while a stopwatch can measure how long your break actually lasted.
