The Pomodoro Interval Method
The standard Pomodoro technique utilizes 25-minute periods of concentrated focus, followed by short 5-minute recovery breaks. This tool allows manual duration overrides to accommodate custom work blocks (like the 52-17 rule).
About the Sound:
The optional focus sound uses the browser's native Web Audio API to synthesize real-time pink noise. Unlike pre-recorded tracks, this is mathematically generated on your local device to run offline and preserve network bandwidth.
Pink noise contains equal energy per octave, resulting in a deeper, softer rustle than harsh white noise, which masks ambient background interruptions more effectively.
