I drove in Congestion Charge Zone / ULEZ and THEN installed this app

Bear in mind that the app uses GPS location to record your position and the app is not connected to TfL system! It might not have your complete travel history.

The app is not able to show you driving history prior to installation.

The app is not connected to any TfL systems and only uses GPS to save time and date when you travelled over the Zone's boundary based on your location.

Please contact the TfL here https://tfl.gov.uk/modes/driving/congestion-charge/contact-congestion-charge 

This app has following limitations and abilities:

• The app is unable to show your previous trips to the Zone, if it wasn't open while driving

• The app might miss entry/exit due to weak GPS signal, we recommend to keep your phone on your dashboard in a phone holder

• This is not an official TfL app, this is a navigational assistance app with a trip diary. It is your responsibility to contact Transport for London and arrange for payments of charges and penalties. 

• It is your responsibility to check with TfL if you have travelled to the Zone on a particular day, if in doubt.

This app will only show you the diary of assumed entries and exits into Congestion Charge zone only if it was open and running while driving. This is because this app is not connected to any of Transport for London systems and is only designed as navigational aid (GPS) for drivers in London.
