Sleep as Android
What Sleep as Android is
Sleep as Android is an Android alarm clock and sleep cycle tracker designed to wake users during an optimal sleep phase. It tracks sleep with phone or wearable sensors, mattress-based accelerometer tracking, or contactless Sonar. Alarm options include gentle sounds and light, sunrise alarms, and online radio alarms. Other tools include sleep deficit statistics, bedtime notifications, lullabies, and alarm-dismissal tasks such as QR codes, NFC, shaking, or math. The app can record sleep talking and snoring and provide snoring and room-noise statistics. Listed integrations include Google Fit, S Health, Zenobase, Fluxtream, Beeminder, Philips Hue, and smart watches such as Pebble, Wear, and Gear. SleepCloud supports sleep-data backup, two-way synchronization across devices, synchronized settings, and a web dashboard. The licensing page describes a 14-day trial with unrestricted feature access. After the trial, the free app plan limits sleep tracking to every other day; alarms, lullabies, CAPTCHA tasks, and bedtime notifications remain unlimited, and ads appear. The maker says the service is informational and does not constitute medical advice.
