8 hours
The 8-hour timer keeps an accurate count down and automatically shows how many 8 hours there are in minutes and seconds. The control buttons are simple and clear, and you can switch to full-screen mode with just one click. At the end, the selected melody sounds, the volume of which can be adjusted or turned off.
The interface adapts to the screen of any device and works stably in the background tab. The remaining time is displayed in the browser header, which is convenient when performing parallel tasks.
