Personal safety device for daily outings

This compact device fits on your keychain and sends a loud alarm and your location to emergency contacts if you feel unsafe. It has a simple button to activate, so you don't need to unlock your phone or fumble with apps. I carry mine during evening walks and public transit rides, and it gives me peace of mind without being bulky or noticeable.
