Accurate fitness tracker, sleep monitor and emergency assistance provider - SAFR does it all, combining all of your favorite wearable smart devices into one product. But what really sets the SAFR apart is an integrated crash/fall alert system. The SAFR senses fall/crash events automatically & accurately, and sends an audible alert to your emergency contacts through an iOS or Android app. We’ve also built in an emergency button so you can send alerts with a press of the button. SAFR is designed to save lives. It is water resistant and has a built in battery that can last up to 7 days.
