Frequently Asked Questions
01 Does the timer work if I switch tabs?
Yes. The timer uses the system clock to calculate elapsed time, so it stays accurate even if you switch to another browser tab or minimize the window.
02 What happens when the countdown reaches zero?
An alarm sound plays using the Web Audio API (a series of beeps). The display flashes to let you know time is up. No external files are loaded — the sound is generated entirely in your browser.
03 Can I record laps with the stopwatch?
Yes. In Stopwatch mode, click the Lap button to record split times. All laps are displayed in a list showing the lap number, lap time, and total elapsed time.
04 Does the timer store my data?
No. Everything runs locally in your browser. Tools Oasis does not store, send, or log any timer data.
05 Can I use the timer in fullscreen?
Yes. Click the Fullscreen button to display the timer in fullscreen mode, making it easy to see from across a room. Press Escape to exit fullscreen.
More Questions About the Timer
01 Does the timer stay accurate when I switch tabs?

02 What happens when the countdown reaches zero?
