Start free with Sleep Cycle phone app

What to Do

Download the Sleep Cycle app and place your phone on the nightstand. It uses the microphone and accelerometer to track sleep patterns and provides a smart alarm that wakes you during a light sleep phase.

Why It Works

Sleep Cycle claims 89% correlation with professional monitoring equipment and provides trend data, snoring detection, and a smart wake-up window. For someone new to sleep tracking, it offers meaningful insights with zero hardware cost.

Tips

• Best for: beginners who want to start tracking without buying a device
• The smart alarm feature (wakes you within a 30-minute window during light sleep) is genuinely useful for reducing grogginess
• Limitation: phone-based tracking is inherently less precise than wearable biometrics
• Free tier is functional; premium ($39.99/year) adds detailed statistics and long-term trends
