Frequently Asked Questions
Is this timer accurate?
Yes. We use the High Resolution Time API (`performance.now()`) to measure the precise passage of time regardless of browser event loop congestion.
Can I run multiple countdowns?
Absolutely. You can add as many countdown timers as you need, label them, and run them concurrently. Each has its own progress tracker and alarm.
