You will gain added security and reassurance using Run Angel, a safety device to wear on your wrist while running. Easy to set up, you will have no problems downloading the app, connecting to your Bluetooth and following the simple instructions. If in need, you press the centre button to emit a very loud 120dB, high-pitched audible alarm, or a silent signal to your ‘chosen guardian’ by pressing a side button that sends a text with your GPS location. Brilliant.
