Sleep Cycle vs Sleep as Android (2026)

Sleep Cycle and Sleep as Android are the two leading phone-based sleep trackers — the apps users compare when they want sleep data without buying a wearable. Both use the phone microphone and accelerometer to detect sleep stages and disturbances; the structural differences are platform reach and customisation depth. Sleep Cycle is the polished cross-platform incumbent; Sleep as Android is the deeply-customisable Android-only specialist.

VERDICT: TIE

Depends on your platform. Sleep Cycle for the polished iPhone and Android cross-platform experience. Sleep as Android for the deepest customisation, automation and integration if you are Android-only.

Sleep Cycle7.2 / 10

Sleep Cycle

Sleep tracking app

The most polished mainstream sleep tracker — a smart alarm and clean analysis, with a genuinely useful free tier.

Urbandroid7.0 / 10

Sleep as Android

Sleep tracking app

The most complete sleep app on Android — tracking, smart alarm and wind-down sounds in one — if you do not mind a feature-dense interface.

Head-to-head breakdown

  • Platform support

    Sleep Cycle: iPhone and Android with full feature parity. Sleep as Android: Android-only. Sleep Cycle wins on cross-platform reach.

    Sleep Cycle

  • Tracking method

    Sleep as Android offers more tracking options — accelerometer, sonar (ultrasound), microphone, plus wearable integration (Wear OS, Garmin). Sleep Cycle uses microphone + accelerometer only.

    Sleep as Android

  • Sleep analytics

    Both produce reasonable sleep-stage estimates and trend analysis. Neither matches a real EEG headband or a wearable like Oura.

    Tie

  • Customisation depth

    Sleep as Android: Tasker integration, smart-alarm automation, custom soundscapes, plugin ecosystem. Sleep Cycle is more opinionated and less customisable.

    Sleep as Android

  • Smart alarm

    Both wake you during light sleep within a configurable window. Equivalent in execution.

    Tie

  • Wind-down content

    Sleep Cycle has a polished sleep-soundscape and sleep-story library. Sleep as Android focuses on tracking and lets the user bring their own audio.

    Sleep Cycle

  • Snore and sleep talk detection

    Sleep as Android records snoring and sleep talk with finer-grained classification. Sleep Cycle detects snoring but the analysis is lighter.

    Sleep as Android

  • Price

    Both freemium with ~$40/year premium tiers. Effectively equal.

    Tie

Choose Sleep Cycle

Choose Sleep Cycle if you want a polished, low-friction sleep tracker that works equally well on iPhone and Android with a clean UX and a real long-term track record.

Choose Sleep as Android

Choose Sleep as Android if you are on Android and want the deepest customisation — Tasker integration, smart-alarm automations, multiple tracking methods, raw data export.

The short version

Sleep Cycle wins on polish and cross-platform reach; Sleep as Android wins on Android-only customisation depth. Pick on platform first, customisation second.

When Sleep Cycle is the right pick

If you want a polished, low-friction sleep tracker that works the same on iPhone and Android, and you value a clean app over deep customisation, Sleep Cycle is the right shape. The sleep-soundscape library and the consistent UX across platforms are the differentiators.

When Sleep as Android is the right pick

If you are on Android and you would rather have automation, plugin ecosystem and granular control than a polished out-of-box experience, Sleep as Android is the right shape. The Tasker integration alone is reason enough for power users. For iPhone users it is not an option.

Common questions

Should I pick Sleep Cycle or Sleep as Android?

Sleep Cycle if you want a polished cross-platform experience that works equally on iPhone and Android. Sleep as Android if you are Android-only and want the deepest customisation, automation and integration depth. Pick on platform first.

Does Sleep as Android work on iPhone?

No — Android-only by design, and the developer has explicitly stated it will stay that way. iPhone users should pick Sleep Cycle or AutoSleep.

Are phone-based sleep trackers accurate?

Reasonably accurate for sleep timing, light-vs-deep estimates and disturbance counts. Neither matches a real EEG headband (Muse S Athena) or a dedicated wearable (Oura, Whoop) for sleep staging. For most users they are accurate enough to track trends.

Can I use either with a smartwatch?

Sleep as Android integrates with Wear OS, Garmin, Samsung wearables and others — using the watch as the sensor instead of the phone. Sleep Cycle has Apple Watch integration but is less wearable-centric.
