Trak2Dor is a GPS function that enables a Post Person working for Dor2Dor to be track whilst they carry out their delivery of leaflets and magazines as they distribute to residential households and business in the drop area. The app will ping the GPS satellites approximately every 5 seconds and via the mobile phone network or WiFi will display this via the host server to the Dor2Dor franchisee’s computer screen. Continued use of GPS running in the background can dramatically decrease battery life.
