Questions Worth Asking
Will light actually wake me up if I'm a heavy sleeper?
Yes. Your eyelids are sensitive to light even during sleep. 30 minutes before your target time, Alarlo gradually fills the room with warm morning light, suppressing melatonin and shifting you out of deep sleep into a lighter slumber. If you still need audio, your chosen gentle soundscape activates at your exact wake time.
How is this different from just using my phone alarm?
Phone alarms trigger a cortisol spike the moment they sound — your body goes from 0 to stress in an instant. Alarlo works with your sleep cycle, not against it, using light to naturally lift you out of deep sleep before any sound plays. You wake up — not startled awake.
Do I need to download an app to use it?
Most Alarlo devices work entirely via tactile buttons on the unit — no app, no Wi-Fi, no Bluetooth pairing needed. Models like Dawn Charge and Aurora Hub offer an optional app for extra customization, but it's never required.
What if it doesn't work for me?
Try it for 30 nights in your own bedroom. If you aren't waking up with noticeably better energy and less morning dread, email us and we'll send a prepaid return label for a full refund. No hoops, no hassle.
Is it safe to sleep with a light on?
Yes. Alarlo's sunset mode dims light gradually as you fall asleep, and stays off through the night. It only begins brightening 20–30 minutes before your alarm — so your room is dark all night and bright only when it's time to rise.
How long does it take to see a difference?
Most customers notice a difference within the first week. Your circadian rhythm responds quickly to consistent light cues — within 3–5 days, your body starts anticipating the sunrise and naturally moves into lighter sleep before your alarm.
