Frequently Asked Questions (FAQ)
How does the floating Picture-in-Picture (PiP) mode help?
The Picture-in-Picture mode keeps a floating miniature clock on your monitor over any app (Google Docs, IDEs, spreadsheets), so you can track your remaining time without switching browser tabs.
Can I customize the timer intervals?
Yes! Click the Settings gear to adjust the focus session, short break, and long break to any duration that fits your personal workflow (e.g., 50/10 intervals for intense study).
How does the Spotify music player integration and auto-sync work?
Our app features a native Spotify mini-player loaded with top study playlists (Lofi Beats, Deep Focus, Peaceful Piano, Coffee Table Jazz) and supports any custom Spotify playlist or album URL. When 'Play only while timer is running' is enabled, the player automatically pauses audio when your timer stops or pauses, and resumes playback instantly when you click Start.
Why is Brown Noise scientifically effective for ADHD and deep focus?
Brown Noise emphasizes rich low-frequency acoustic vibrations that simulate deep waterfall roar or heavy rain. Scientific research in cognitive neuroscience demonstrates that brown noise successfully neutralizes disruptive background spikes, soothes an overactive nervous system, and provides optimal sensory stimulation for ADHD minds without causing sensory fatigue.
Can I control the timer directly from the Picture-in-Picture window?
Yes! Unlike generic video-based timers, our app utilizes the modern Document Picture-in-Picture API. You get active Start, Pause, Reset, and Skip/Break buttons directly inside the floating mini-window, allowing you to control your session while working across any application.
Will the focus timer freeze or lose time if my smartphone locks?
No. We engineered a robust system with hardware clock drift correction, Page Visibility API monitoring, and Screen Wake Lock integration. When your screen turns back on, the timer instantly synchronizes to the exact elapsed millisecond and reliably triggers audio chimes.
