Frequently Asked Questions
Can't fall asleep -- what should I do?
Try white noise for sleep. A steady background sound helps the brain transition from an alert state to relaxation. Sleep Island offers free rain, ocean waves, fireplace, and many other white noise options. Also, maintaining a regular sleep schedule, avoiding screens 1 hour before bed, and keeping your bedroom at 18-22 degrees Celsius can help.
How can I increase deep sleep?
Deep sleep above 20% is considered normal. To improve: maintain a regular sleep schedule, avoid caffeine and alcohol before bed, exercise moderately (but avoid intense exercise within 3 hours of bedtime), and use white noise to create a quiet environment. Sleep Island can track your deep and light sleep proportions.
Does white noise really help with sleep?
Yes. Multiple studies confirm that white noise can shorten the time to fall asleep and reduce nighttime awakenings. It provides a steady sound background that masks sudden environmental noises, preventing your brain from being startled awake. Natural white noise (rain, ocean waves) is more comfortable than mechanical white noise.
How is Sleep Island different from other sleep apps?
The core difference is AI-powered analysis: not just data, but an AI assistant that interprets your sleep like a friend and gives personalized advice. Snore detection can intelligently distinguish between snoring, sleep talking, and environmental noise. It also supports tinnitus relief. Core features are completely free.
What should I do about severe snoring?
First, use snore detection to understand the severity. Mild (fewer than 10 times per hour): try sleeping on your side. Moderate (10-30 times): pay attention to weight and sleeping position. Severe (more than 30 times): consult a doctor to check for obstructive sleep apnea (OSA).
My tinnitus is especially bad at night -- what can I do?
Tinnitus is more noticeable in quiet environments. Sound masking therapy is the most recommended relief method: use natural white noise like cricket sounds to mask the tinnitus. Sleep Island has a dedicated tinnitus relief sound series. If it continues to worsen, consult a doctor.
Is Sleep Island free?
Core features are completely free: sleep tracking, snore recording, white noise for sleep, and tinnitus relief. No 7-day trial, no forced subscription.
Do I need a smartwatch for sleep tracking?
No. Sleep Island detects body movement through your phone's sensors to determine when you fall asleep, light sleep, deep sleep, and waking. Just place your phone on the bed or nightstand -- it works even with the screen off.
