The eTollTracker Android app is designed for the South African Toll Roads (Gauteng currently). Using GPS coordinates from your built-in GPS on your smartphone it calculates (using mathematical equations) your position and bearing and calculates the e-tolls as you pass through the gantry.
No need to take eyes of the road as this App will automatically record the gantries.
The calculation is based on SANRAL cost calculations taking into affect the time of day, the vehicle type and if you are a registered e-tag user. You can also run reports and get daily and montly totals to compare with your invoices from Sanral. Updates will be done regularly to ensure eToll feesare kept up-to-date.
