Which Android app should I use for keeping track of a special needs adult or child who wanders?

AngelSense Guardian is a specialized safety solution designed for caregivers of individuals with conditions like autism, dementia, or other special needs that may lead to wandering. The system centers on a dedicated GPS device worn by the loved one, paired with this Android monitoring app. Its primary strength is providing precise, real-time location tracking and instant notifications if the person crosses a pre-set geographic boundary, known as a geofence. This allows for rapid response in critical situations. Beyond tracking, the app enables one-way voice monitoring, where the caregiver can listen to the wearer's surroundings without requiring them to answer a call, a vital feature for non-verbal individuals or during moments of distress. Reviews indicate the accompanying wearable offers a robust battery life, often lasting multiple days, and can be secured in a soft belt or pinned to clothing to prevent removal. While the service requires a monthly subscription and the purchase of proprietary hardware, users consistently report it delivers essential peace of mind. The app interface is noted for being straightforward, with easy access to location history, safe place naming, and device management settings.
