The short version

  • Only Sleep Cycle has a free tier, so it costs nothing to try first.
  • Each has a real cost: Centr centr Coach app subscription pricing not disclosed on website; Sleep Cycle sleep stage detection is inferred from sound and motion rather than measured with dedicated physiological sensors, so accuracy is lower than a ring or watch based tracker like Oura.
  • They diverge on capability: Centr covers Expert-led workouts, Sleep Cycle covers Sound and motion sleep analysis.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Centr

  • Centr Coach app subscription pricing not disclosed on website
  • Specific app subscription terms and feature details unavailable
  • Equipment is sold individually with no bundled pricing packages mentioned

Sleep Cycle

  • Sleep stage detection is inferred from sound and motion rather than measured with dedicated physiological sensors, so accuracy is lower than a ring or watch based tracker like Oura.
  • The app needs to run overnight with the microphone active or the phone on the mattress, which raises its own privacy consideration for anyone uncomfortable with a phone microphone recording an entire room overnight.
  • Most of the features that make the sleep data actionable, detailed trends and snore analysis, are behind the Premium subscription rather than included free.
  • Battery drain overnight from continuous microphone or motion sensing is a real practical issue for anyone who also wants to use the phone as a normal alarm without charging it.
  • Detection can be disrupted by a shared bed, a partners movement or snoring, or ambient household noise, all of which reduce accuracy for the primary user.
