We have covered a bunch of interesting personal safety devices here in the past. Wearsafe happens to be another wearable device that gets you in touch with your loved ones with the press of a button. The device is compatible with your smartphone and smartwatch (e.g. Pebble Time).
When activated, an alert with your location, speed of travel, and streaming audio is sent to your contact list. The Wearsafe Tag has a range of up to 200 feet. It does help that you can wear your Wearsafe Tag in various ways. The battery lasts for up to 6 months. More information is available here.
