Try white noise. Consistent background sounds like rain or ocean waves help your brain transition from alert to relaxed. Sleep Island offers free high-quality white noise. Also: keep a consistent sleep schedule, avoid screens 1 hour before bed, and keep your bedroom cool (64-72°F / 18-22°C).
Deep sleep at 20%+ of total sleep is normal. To improve: maintain a regular schedule, avoid caffeine and alcohol before bed, exercise regularly (but not within 3 hours of bedtime), and use white noise. Sleep Island tracks your deep/light sleep ratio.
Yes. Multiple studies confirm white noise reduces time to fall asleep and nighttime awakenings. It provides a steady sound backdrop that masks sudden noise (traffic, neighbors). Natural white noise (rain, ocean) is more comfortable than mechanical noise for long-term use.
Our core difference is AI-powered analysis: instead of just numbers, our AI companion interprets your sleep and gives personalized advice. Snore detection uses AI to tell snoring from sleep talking and noise. We also offer tinnitus relief. All core features are free — no trial limits, no forced subscriptions.
First, use snore detection to understand severity. Mild (<10/hr): try side sleeping. Moderate (10-30/hr): focus on weight and position. Severe (>30/hr): see a doctor to check for obstructive sleep apnea (OSA).
Tinnitus is more noticeable in quiet environments. Sound masking therapy is the most recommended approach: use cricket sounds or natural white noise to mask it. Sleep Island has a dedicated tinnitus relief sound library. If it worsens, see a doctor.
All core features are free: sleep tracking, snore detection, white noise, tinnitus relief. No 7-day trial. No forced subscriptions.
No. Sleep Island uses your phone's built-in sensors to detect movement and determine sleep stages. Place your phone on the bed or nightstand. Works with the screen off.
