GuardKit is designed to help you understand when your device may have been moved or interacted with while you were away. GuardKit works by running user-initiated Guard Sessions that analyze motion signals such as acceleration, orientation changes, and handling-like movement patterns. If you choose to enable it, GuardKit can also monitor nearby audio activity levels to provide additional context. All analysis is performed on-device. Key features: • Motion-based activity indicators during active Guard Sessions • Optional audio activity level detection (no audio recording) • Clear, chronological timelines of detected events • Local-first data storage — your data stays on your device • Full user control over permissions and features Premium access: GuardKit offers a free 3-day trial with full access to premium features. After the trial, premium access is available via a one-time purchase (Lifetime Unlock). No subscriptions are required. Learn more at https://www.guardkitapp.com
