Not enough variety of questions. Sometimes the same sign occurs twice in a single quick quiz of 20 questions, and again if you take another quick quiz right after. The app is also confusing to negotiate. I should think an app testing you on every road sign would be easy to create, but apparently not.

This is a good app for learning. The issue I've had is the are not enough questions in the quiz section. Only 150. You get the same questions over and over every time you do a quiz. There should be a question about every sign. More questions would make this a 5* app.

Good as far as it goes, but disappointed at the omission of the variety of Road Closed signage.

Disappointing

Bear in mind that it doesn’t test your knowledge of ALL road signs and markings, just a minor selection of them. If there’s signs or road markings you have trouble with this may not help you. The practice section asks questions not really related to road signs, but car/bus/lorry driving theory, which for many users will be irrelevant. Kind of false advertising. Waste of money: I wanted to get the knowledge from the og source and got less than I’d find for free on the internet.

Very useful app to have in your pocket. This app is targeted at new drivers, both car and motorcycle. This is aimed at getting you through your theory test as well as being able to recognise road signs when driving. They have missed several audiences when it comes to the ‘self assessment’ through the practice and tests. For more advanced driving, the test and practice modes are limited in their breadth (150 questions) and recycle the same limited amount of options over and over. Those who are taking further driver training, whether that be HGV, PSV require a more thorough knowledge of both the Highway Code and Traffic Signs, as the pass mark for your theory is higher. Those partaking in Advanced Driver Training either as a DVSA Driving Instructor or anyone working with the road safety charities IAM or RoSPA, who almost need to be able to recite the rules and regulations verbatim, will find the testing here, is insufficient for their needs. I mean, who doesn’t need a better knowledge of how to drive and the driving environment??

Works great but will occasionally freeze.

I think it freezes on pages with more pictures than text? Usually after a few minutes it will unfreeze

Recommended for all road users !

An excellent app, everything is very well laid out. The quizzes are great, you can easily configure them to suit, they even have separate practice and test modes. You’re given the results straight away and can even go back and review your answers at the end. An invaluable aid to brushing up on your knowledge, whether a learner or experienced driver or rider.
