## What is Posture Guardian?

Posture Guardian is a personal wrist-posture reminder designed exclusively for Apple Watch.

Train the wrist positions you commonly use while lying on your left or right side and using your phone. Start a monitoring session, and the app compares your current wrist state with your trained postures directly on Apple Watch. When a similar state reaches your selected reminder threshold, the watch reminds you to adjust with a haptic alert or local notification.

FEATURES

• Personal posture training for both sides and for using either hand to hold your phone.
• On-device posture matching using Apple Watch motion sensors.
• Reminder thresholds of 10 seconds, 30 seconds, or 1 minute of cumulative matched posture time.
• Monitoring plans of 1 to 6 rounds, with a target of approximately 10 minutes per round.
• Accurate and false-positive feedback to refine your local personal model.
• Additional posture templates and local diagnostic summaries.

PRIVACY

No account is required. Raw motion data is not uploaded. Your posture models, feedback, and settings remain on your Apple Watch.

The app does not read your phone screen, active apps, or Screen Time.

HOW REMINDERS WORK

The reminder threshold counts cumulative time during which a trained posture is reliably matched. It is not a general countdown. Timing may pause when you move, change hands, or no reliable match is available.

Continued monitoring depends on watchOS runtime conditions and system resources.

IMPORTANT

Posture Guardian detects wrist states similar to your training samples. It cannot confirm that you are using a phone or lying on your side. False positives and missed reminders can occur.

This is a general habit-reminder tool, not a medical device. It does not provide diagnosis, treatment, or professional medical advice.

Requires Apple Watch with watchOS 10.0 or later. The app interface supports English and Simplified Chinese.
