With this app you can exchange by bluetooth or SMS your personal information, your cars information and your insurance companys data. Download the other persons data file. Then, take photographs of the accident and explain it writing below. Save the file and send it by email to your insurance company, and to the police if necessary. This file contains relevant information: date, time, geolocalization, information of all involved in the car crash.
You can also call or send automatic SMS to: ambulance, police, firefighters, tow truck and family or friend. This last one has a button to send your geolocalization and an antipanic button in case you have been kidnapped. Its the best because it sends all the information instantly to your family or friend, who will then call the police.
