Frequently Asked Questions
Q: Will the alarm still go off if I switch browser tabs or minimize the window?
Yes. The web alarm clock runs continuous time checks in the browser and will ring and play audio even when running in a background tab or minimized window. You can also grant desktop notification permissions so a visual notification alert pops up when the alarm fires.
Q: Does the alarm clock work offline without an active internet connection?
Yes. All audio synthesized tones (Chimes, Digital Beep, Marimba, Synth Arp, Zen Bowl, Siren, Birdsong) and clock timers run 100% client-side inside your browser via the Web Audio API. No ongoing internet connection is required once the page is loaded.
Q: Can I upload and use my own custom MP3 music or audio file as an alarm tone?
Yes. In the Sounds & Tones tab or within the alarm creation modal, you can upload any local MP3, WAV, or OGG audio file to play as your personalized wake-up track directly in the browser.
Q: How does the Sleep Cycle Calculator help me wake up refreshed?
Human sleep cycles typically run in 90-minute REM cycles. Waking up midway through a deep sleep cycle causes sleep inertia and grogginess. The built-in Sleep Calculator computes the optimal bedtimes and wake times (e.g. 7.5 hours for 5 complete cycles) so you can wake up between cycles feeling naturally energized.
Q: What is the Math Challenge wake-up mission feature?
To prevent accidental dismissals when half-asleep, you can enable the Math Challenge option on any alarm. When the alarm rings, you must solve a quick mental arithmetic problem (such as addition or multiplication) to successfully dismiss the alarm.
