With this app, you can make a telephone roll call with a driver as if you were a videophone.
In addition to measuring alcohol, you can see the driver's face, so you can check your health and make your operation safer.
In addition, the location where the driver is located is obtained from the GPS location information and recorded automatically.

If you cannot make a videophone call in a place where the mobile phone signal condition is not very good, you can perform alcohol measurement by offline measurement.
