SleepWalking Shield is a dedicated watch app designed to support people who struggle with sleepwalking. Start a session on your watch before you fall asleep and let it quietly monitor for walking movements during the night. If SleepWalking Shield detects that you may be walking in your sleep, it gently wakes you with haptic vibration and sound that increase in intensity if you keep moving. With the companion iPhone app, you can review when potential sleepwalking episodes occurred, including the time and your heart rate at that moment. Over time, you can build a clearer picture of how often you may be sleepwalking and when it tends to happen. SleepWalking Shield is built for people and families affected by sleepwalking who want extra peace of mind at night. The app is completely free to use. Key features: Watch sleepwalking sessions: Start monitoring directly from your wrist before bed and let your watch do the work while you sleep. Gentle wake-up alerts: Receive subtle vibrations and sounds that gradually intensify if you continue walking, helping you wake up more calmly than a sudden loud alarm.​ Episode timeline on iPhone: See when potential sleepwalking episodes occurred and view your heart rate at those times in the companion iPhone app. Designed for sleepwalking: Focused specifically on walking during sleep, not just general sleep tracking or snoring.​ Privacy by design: SleepWalking Shield does not collect or share any personal data. There are no user accounts and no third‑party analytics. Your information stays on your devices. Completely free: No in‑app purchases, subscriptions or paywalls. Requirements: A watch is required to use SleepWalking Shield. The app relies on your watch to detect walking movements and deliver gentle alerts. The iPhone app is used to view your sleepwalking timeline and related heart rate data recorded by the watch. Important: SleepWalking Shield is a supportive tool and is not a medical device. It does not diagnose, treat, cure or prevent any sleep disorder or health condition. Always speak to a healthcare professional for advice about sleepwalking or other sleep issues.
