## What is D?

D-one is a vest for the protection and safety of runners that is able to send, via a smartphone, an e-call in the event of an emergency and is able to identify a fall followed by lack of movement to activate the call automatically, also sending a geolocated text message.

Using this app you can communicate with your vest at all times.

* Set your preferred contacts
* Send an e-call to your contacts in an emergency
* Send geolocated text messages to your contacts in an emergency
* Increase your visibility through activating and adjusting the LEDs integrated in the vest
* Monitor the level of charge of the device and periodic updates
