Sleep as Android

Prague, Czechia

What it is

Sleep as Android is an Android alarm clock and sleep cycle tracker that aims to wake users during an optimal sleep phase. It can track sleep with phone or wearable sensors, a mattress-based accelerometer, or contactless Sonar. Alarm choices include gentle sounds and light, sunrise alarms and online radio. Other tools include sleep deficit statistics, bedtime notifications, lullabies and dismissal tasks such as scanning a QR code, using NFC, shaking the phone or solving math. The app can record sleep talking and snoring, then provide snoring and room-noise statistics. Listed integrations include Google Fit, S Health, Zenobase, Fluxtream, Beeminder, Philips Hue and several smart watch platforms. SleepCloud offers backup, synchronization across devices, synchronized settings and a web dashboard. The licensing page describes a 14-day trial with unrestricted feature access. After the trial, free app users can track sleep every other day; alarms, lullabies, CAPTCHA tasks and bedtime notifications remain unlimited, and ads appear. The maker says the service is informational and not medical advice.

The review

Sleep as Android is an Android alarm clock and sleep tracker for people who want to use sleep patterns to shape when and how they wake. It pairs flexible tracking and alarm tools with integrations and cloud backup, though the free plan cuts tracking to every other day after its trial.

Overview

The app aims to wake you during an optimal sleep phase, using phone or wearable sensors to track sleep. Its range of tracking methods and alarm options makes it a strong fit for Android users who want sleep monitoring and wake-up controls in one app. The every-other-day tracking cap and post-trial ads make the free plan a limited long-term choice for regular tracking.

Key features

Tracking can use phone or wearable sensors, a mattress-based accelerometer, or contactless Sonar. That variety gives users more than one way to collect sleep data, including an option that does not rely on contact with the phone or a wearable. Sleep deficit statistics and bedtime notifications add context and routine prompts, while sound monitoring can record sleep talking and snoring and report snoring and room-noise statistics.

The smart alarm is the app’s central appeal: it aims to time wake-ups for an optimal sleep phase, with gentle sounds and light, sunrise alarms, and online radio. Lullabies and alarm-dismissal tasks such as scanning a QR code, using NFC, shaking the phone, or solving math add practical controls for winding down and getting out of bed. Those options suit users who want a configurable sleep routine; they do not remove the free plan’s tracking cap.

Integrations include Google Fit, S Health, Zenobase, Fluxtream, Beeminder, Philips Hue, and smart watches including Pebble, Wear, and Gear. SleepCloud can back up sleep data, synchronize it across devices, sync app settings, and provide a web dashboard. Its free tier backs up once per week; more frequent backup requires SleepCloud FULL.

Privacy controls include an option to opt out of anonymous usage statistics, disable sleep location, and enable Scoped Storage so the app’s access is limited to its designated folder. The maker says location is coarse, at roughly five-kilometer accuracy, rather than an exact address. Local backups can also be enabled. The service is informational and does not constitute medical advice.

Pricing

Sleep as Android is freemium. Its licensing page describes a 14-day trial with unrestricted access to all features. Afterward, the free app keeps alarms, lullabies, CAPTCHAs, and bedtime notifications unlimited, but limits sleep tracking to every other day and adds ads. That suits occasional trackers, but is a meaningful constraint for anyone who wants nightly records.

SleepCloud FREE costs nothing and provides a web dashboard and online account, with backup once per week. SleepCloud FULL is billed as a small yearly fee, with no amount stated; it backs up each tracking session. A monthly Sleep as Android subscription includes SleepCloud FULL.

The Subscription plan is billed yearly, with custom pricing, and includes SleepCloud PRO and an extra week of trial. The Unlock App is a separate license-key app with custom pricing and Google Family Library support, billed as a one-time purchase. In-App Lifetime is also custom pricing and a one-time purchase, offering lifetime access with an occasional internet connection required for license verification. These paid routes remove the free plan’s tracking restriction in different ways, but the price details given do not support a direct cost comparison.

Platforms

Sleep as Android is available on Android. Wearable sync is supported, but the app’s mobile platform is Android.

Who it's for

Choose it if you use Android and want sleep tracking alongside a smart alarm, routine tools, sound monitoring, wearable integrations, and optional cloud backup. It is less suitable if you need unrestricted nightly tracking at no cost, use iOS or desktop as your main platform, or need medical advice.

Pros and cons

  • Pro: Multiple tracking methods, including contactless Sonar and mattress-based accelerometer tracking, give users options for how to monitor sleep.
  • Pro: Smart alarms, sunrise and radio alarms, lullabies, and CAPTCHA dismissal tasks support a flexible sleep and wake routine.
  • Pro: SleepCloud offers cross-device synchronization and a web dashboard, with weekly backup available for free.
  • Con: Free sleep tracking drops to every other day after the trial, making the free plan unsuitable for consistent nightly records.
  • Con: Ads appear after the trial, and the paid plans have custom pricing, so the ongoing cost is not clear from the plan terms.
  • Con: The app is Android-only, which rules it out for users who need an iOS app.

Verdict

Sleep as Android is a good choice for Android users who want sleep tracking, varied alarm options, and routine tools in one app. Its broad tracking and integration choices are the strongest reasons to choose it; the every-other-day free tracking limit and unclear paid prices are reasons to look elsewhere if you need nightly tracking at a predictable cost.
