## What is NeckGuard?

When you use a smartphone, your head tilts forward by an average of 38.9 degrees.
At just 30 degrees of forward tilt, the load on your cervical spine is about four times that of a neutral posture.
NeckGuard uses the motion sensors in your AirPods to detect that dangerous angle in real time and protect your neck.

[ Why both angle AND time matter ]
Research suggests that both a large forward tilt (20-45 degrees) and long sustained duration (more than 2 hours a day) contribute to forward head posture. NeckGuard watches both at the same time.

[ Main features ]

- Real-time angle measurement
Continuously monitors your head's forward tilt using the AirPods motion sensors.

- Personal calibration
Just sit up straight and tap a button to register your own neutral posture.

- Two-stage detection: angle x time
Combines a threshold angle (10-60 degrees) with a duration (3-30 seconds), so alerts fire accurately while false positives stay low.

- Alerts you can choose
Haptic only, voice only, or haptic + voice. Haptic strength can be set to Light, Medium, Strong or SOS.

- Tilt angle graph
Look back at how your angle changed over the session.

- Monitoring sound and background operation
While monitoring, NeckGuard plays a calming ambient sound (ocean waves, stream or white noise, with an adjustable volume). This continuous playback also keeps monitoring running after you return to the Home Screen or turn the screen off.

- A caution built in, backed by evidence
Holding one "perfect" posture without moving is also a load on your neck and shoulders, so the app tells you not to make the settings too strict and recommends standing up and moving every 30-60 minutes.

[ Supported devices ]
AirPods Pro (1st and 2nd generation), AirPods (3rd generation), AirPods Max
Note: AirPods (1st and 2nd generation) are not supported.

[ Please note ]
This app is not a medical device. It is not intended to diagnose or treat any neck condition; it is an everyday aid for becoming aware of your posture.


## Version history (last 5 releases)

### 1.2.0 — 2026-08-20

- All spoken alerts now use natural-sounding voices (choose female or male in Settings).
- Alerts are easier to hear while listening to music: louder speech and improved audio handling.

### 1.1.1 — 2026-08-17

Improved background stability.
- Fixed an issue where monitoring could stop after a voice alert while the app was in the background.
- After an alert, when your posture returns to normal the alert now ends automatically, the counter resets, and monitoring continues seamlessly.

### 1.1.0 — 2026-08-16

- Added a "Posture History" calendar.
  Your daily tilt data is now recorded automatically, and the month view colour-codes each day by how much time you spent over the threshold (green: under 15%, orange: 15-30%, red: over 30%).
  Tap any day to see its monitoring time, time in bad posture, over-threshold ratio, average and maximum angle, and number of alerts.
- Only daily summaries are stored on your device. Nothing is transmitted externally.

### 1.0.1 — 2026-08-04

- Added English support.
- New "Monitoring Sound" feature: a calming ambient sound (waves, stream or white noise) plays while monitoring, with an adjustable volume.
- Added an evidence-based caution not to set the thresholds too strictly, since staying frozen in one posture is also a load on your neck and shoulders.

### 1.0.0 — 2026-07-26

No release notes.
