103 minutes
The 103-minute timer counts down to the nearest second and displays the remaining time on the screen. The Start, Pause and Reset buttons are available — navigation is simple and does not require unnecessary actions. You can choose the appropriate end signal, adjust its volume, or turn off the sound completely. The timer also informs the built-in calculator about the duration in other time units, so you can find out how much 103 minutes are in seconds and hours.
The interface adapts to the device's screen, whether it's a smartphone or a computer. By switching to full-screen mode, you can focus exclusively on time — all secondary elements of the site will be hidden. Even when switching between tabs, the countdown continues smoothly, and the end time is visible in the tab title.
