Help shape NightPosture.
We are inviting a small group to test NightPosture’s local-first position tracking, morning summaries, and early sensor workflow. Fill out the form below to choose a list.

Chest Sensor Interest List
Be First to Hear About the Chest Sensor
NightPosture is being tested with a dedicated chest-worn sensor. The pilot includes one-tap connection, placement-aware Back and side calibration, onboard recording while the phone is locked, local recovery, and configurable nudges after Back remains confirmed. Select “Join Chest Sensor Interest List” or “Join Both Lists” above, and optionally tell us how you would prefer to wear it.
“Interest list” means interest only. The sensor workflow is experimental and limited to a small pilot. We are not taking payment, reserving units, or promising a price, release date, or availability.
Common questions
Do I need any special hardware?
Not for the iPhone fallback, which uses the phone's built-in motion sensors. The experimental sensor pilot uses a dedicated chest-worn sensor and is currently available only to a small test group.
How do I get in once I'm selected?
We invite selected testers through Apple's TestFlight when a spot opens. Adding your email here is a request to be considered — it does not grant immediate access, and we'll share TestFlight details directly with you when you're selected.
Is the chest sensor interest list a purchase or reservation?
No. Joining records your interest — including any optional attachment or price-range preference you share — and lets us send sensor availability updates. There is no payment, reserved unit, guaranteed price, launch date, or promise of availability.
Where does my sleep data go?
Detailed position data and raw sensor data stay on your device, and raw high-frequency sensor data is never uploaded. Debug information is only ever exported through an explicit sharing action you take. See our Privacy page for details.
Can it use Apple Health or Oura?
Optionally. With your permission, NightPosture can read available Apple Health context (sleep stages, heart rate, HRV, respiratory rate) and, experimentally, daily Oura Sleep, Readiness, and Activity scores — used only for local nightly comparisons and source-labeled trends. NightPosture does not write measurements back to Apple Health or claim that position caused a score.
Is NightPosture a medical device?
No. NightPosture is a personal wellness tracker. It does not diagnose, treat, or prevent any medical condition, and it is not a substitute for professional medical evaluation. If you have concerns about your sleep health, speak with a doctor.
How many beta spots are available?
We are keeping the initial group small so we can give proper attention to feedback. We will reach out as spots open.
