Why another fuel log application?

GpsFuelLog-promo graphic The application is not a simple fuel log, it is targeting companies using fuel cards or demanding accurate data when their employees are buying gas.


The need for the application started when we have been involved in a discussion about the fuel card frauds. The convenience of the fuel card is overshadowed by the users who are using it for their personal use; businesses are trying to curb the habit but there is not easy with a fleet of different vehicles whose fuel consumption is all over the map – a vehicle loaded has a total different fuel consumption than one running with no load, a light truck has a different fuel consumption profile than a long haul truck, etc…


When a driver refuels he is asked to fill-up an entry form where several elements have to be recorded:

  • automatically the GPS location is detected, the address is generated and added to the record along with the date&time of the transaction
  • the price/liter or price/gallon has to be manually entered
  • the total price for fuel has to be manually entered
  • A picture of the receipt displaying  the date&time, the address  and information about the fuel price and quantity has to be taken. Here the information has to be the same as the one collected by the GPS data (regarding the location and date&time). Also, the information has to be the same as the one entered manually about the fuel price per unit and total amount spent on fuel.
  • A picture of the odometer has to be taken. The odometer value on the form has to coincide with the one visible in the image.


The application enforces several conditions for people using fuel cards:

  • the fuel card, the user and company’s car have to be present at the location where refueling happens
  • the information needed to calculate fuel consumption is backed-up by the pictures of the receipt and odometer


The application has other features which I will enumerate here:

  • operates with liter/US gallons/UK gallons
  • creates reports and draws charts for fuel consumption for weeks, months or defined periods of time
  • offers the possibility to export data in CSV/HTML format along with the pictures of the receipt and odometer
  • allows importing the data and the pictures for the receipt and odometer (PRO version)
  • emails the back-up (CSV file and images) using a Google email account set by the user (PRO version)
  • prevents the user to enter erroneous data by asking for the capacity of the fuel tank
  • it automatically increments the odometer
  • it does not allow adding past transactions (because GPS data is essential)
  • the user can review past fuel records with full access to the map location of the fueling and the images of the odometer and receipt

Differences between free and paid version

The free version is limited by:

  1. the export operation is only for the last two weeks
  2. the fuel transactions is showing only the last 1o

The paid version of the application will remove the above restrictions and also include:

  • the possibility to manage several vehicles
  • will also allow to quick add a fuel transaction by allowing to save the record with only the GPS location and the shot of the odometer and of the receipt
  • the user can change values entered manually (odometer, price/liter, total price) after the record was saved (which is not possible in the free version; the other elements (GPS info, pictures of the odometer and picture of the receipt) cannot be changed. We called it “fast-form” because you have to take two pictures and wait for the GPS to get the location and should happen in less than 30 seconds.
  • the option to import the back-up data to another phone


Future developments

We also consider the back-up feature to be extended to Google drive or Dropbox.
