All Car Check is a free iPhone application designed for users to easily access the history of any UK Mainland and Northern Ireland registered vehicle by simply searching the registration number. The app provides comprehensive information such as whether the vehicle has been written off, stolen, scrapped, imported, exported, has outstanding finance, and more.

A notable feature introduced in the latest version, AllCarCheck V2.01, is the Vehicle Valuation powered by Glass, known as "the Car Dealers Bible." Users can now obtain valuations similar to those used by nationwide dealers to determine the accurate value of their vehicle, adjusted for mileage.
