Question 1

How does this timer achieve drift-free precision when browser tabs are in the background?

Accepted Answer

Standard browser timers using setInterval experience heavy throttling (up to 1000ms delay) when tabs are placed in the background. Our chronometer uses delta timestamp tracking against system epoch (Date.now() and performance.now()). Every tick recalculates remaining duration directly against the fixed target timestamp, ensuring sub-2ms precision regardless of tab backgrounding or sleep.

Question 2

How are the ambient soundscapes (Brown Noise, Pink Noise, 40Hz Gamma) synthesized?

Accepted Answer

All audio is synthesized in real-time client-side using the HTML5 Web Audio API with zero external MP3 downloads. Brown Noise uses Brownian motion random-walk integration with biquad lowpass filtering, Pink Noise uses a 1/f filter network, and the 40Hz Gamma tone modulates a pure carrier sine wave to stimulate neural cognitive synchrony associated with intense working memory concentration.

Question 3

What is the purpose of the Distraction Audit Ledger?

Accepted Answer

Based on cognitive psychology research, awareness of interruptions is the first step to eliminating them. The "Log Distraction" button allows you to instantly tally an interruption with 1 click. At the end of the session, your Distraction Metric and hourly interruption rate are recorded alongside task objectives, revealing which tasks provoke cognitive friction.

Question 4

Are my tasks, session durations, or distraction counts saved to a server?

Accepted Answer

No. 100% of timer states, audio DSP synthesis, task objectives, and session logs execute strictly in volatile client-side browser memory. Zero tracking cookies or cloud storage APIs are used.
