NeckAlign Support Center

NeckAlign uses Apple’s Headphone Motion Tracking technology. The following Apple and Beats headphones with motion sensors are supported:

• AirPods Pro: All generations (AirPods Pro 1st generation, 2nd generation, 3rd generation or newer)
• AirPods: 3rd generation or newer
• AirPods Max: All models
• Compatible Beats: Beats Fit Pro, Beats Studio Pro, and other Beats models with spatial audio / motion tracking support

1. Connect: Put on your compatible AirPods and grant motion permissions when prompted on first launch.
2. Calibrate: Sit up straight in your ideal, healthy posture and tap Calibrate to establish your baseline.
3. Train: Start your training session! The app monitors your head tilt continuously in the background.
4. Correct: If you slouch past your customized limit, you will receive an audio alert directly in your headphones to remind you to straighten up.

• Verify AirPods connection: Make sure both earbuds are placed in your ears and actively connected to your iPhone (visible in iOS Control Center).
• Motion Permission: Open iOS Settings > Privacy & Security > Motion & Fitness and ensure NeckAlign is enabled.
• Reconnect: Place your AirPods back into the charging case for 5 seconds, then put them back on.

Yes, but an active posture training session must be running.

For NeckAlign to continuously monitor your posture and deliver audio alerts in the background, you must tap Start Session before leaving the app or locking your screen:

• Free Version: Includes 1 session per day, running for up to 15 minutes.
• Unlock Pro: Allows unlimited sessions per day, with deep work sessions lasting up to 4 hours each.

While a session is active, you can freely switch to other apps, write code, listen to audio, or lock your phone — subtle audio nudges will sound directly in your AirPods whenever your posture exceeds your configured limit.

You have full control over your training limits:

• Customizable Sensitivity: Adjust the posture angle threshold to match your personal mobility and comfort level.
• Smart Alert Delays: Set exactly how many seconds you can remain in a poor position before an alarm triggers. This prevents annoying false alarms when you simply lean down to pick up a pen or check your desk drawer.

NeckAlign is designed so anyone can build better posture habits, with Pro available as a simple one-time payment for extended use:

No recurring subscriptions — just a single, one-time payment supporting an indie developer.

2. Open NeckAlign and navigate to the Upgrade / Settings screen.
3. Tap Restore Purchases. Your purchase will be verified instantly with Apple App Store without charging you again.
