A clearer picture of how you sleep through the night.
A small chest-worn motion sensor tracks position while your phone is locked, provides optional back-position nudges, and pairs the night with locally available Apple Health and Oura context.
Private beta. No purchase required.
A closer look
A focused setup at night and an honest, useful summary in the morning.

Three simple steps
Connect and calibrate
Secure a small MetaMotionS+ sensor at your chest, then save Back, Left, and Right baselines in a guided setup.
Track with the phone locked
The sensor keeps an onboard backup and can deliver configurable nudges after Back remains confirmed. NightPosture imports the session when you stop.
Review the full context
See position, tracking quality, turns, nudge estimates, seven-night trends, and optional Apple Health or Oura context—without implying causation.
Your nights are personal.
NightPosture is designed local-first. Detailed position data and raw sensor data stay on your device, and raw high-frequency sensor data is never uploaded. Any Apple Health or Oura context you connect is used only for local nightly comparisons.
Small sensor. Less overnight friction.
NightPosture now works in a limited pilot with an off-the-shelf chest-worn MetaMotionS+ sensor. It supports one-tap reconnect, placement-aware calibration, onboard overnight recording, local recovery, and configurable vibration nudges after your Back position remains confirmed.
From fixed alerts to more personal insight.
Pattern-aware summaries
Compare position and tracking quality over multiple nights instead of drawing conclusions from a single session.
Sleep-metric context
Place position patterns beside permissioned Apple Health and Oura metrics while keeping each source clearly labeled.
Adaptive nudges
Our roadmap explores personalization that can learn which timing and nudge patterns are least disruptive for an individual. This capability is not available yet.
NightPosture is a personal wellness tracker. It does not diagnose, treat, or prevent any medical condition.
