The short version
- Only Sleep Cycle has a free tier, so it costs nothing to try first.
- Each has a real cost: 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.; Tempo heart rate monitor requires direct line of sight to connect and frequently loses connection during workouts
- They diverge on capability: Sleep Cycle covers Sound and motion sleep analysis, Tempo covers 3D motion tracking.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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.
Tempo
- Heart rate monitor requires direct line of sight to connect and frequently loses connection during workouts
- Form feedback can be inconsistent and often misses nuance in exercise execution
- Weight guidance recommendations are frequently inaccurate
- Loud cooling fan sounds like a server or gaming PC, creating noise disturbance during workouts
- High cost of entry plus ongoing $39/month subscription with penalties for returns
