The Manoeuvres app for iPad has been updated to enable drawing on the view. This feature has been added for the benefit of instructors using the app in lessons.
Manoeuvres is ideal for anyone who wants to get to know UK driving manoeuvres inside-out. All manoeuvres are broken down into stages so you can work through them step by step. Each stage is animated, and you can skip forwards and backwards through the animations as needed.
The app also includes full briefings for each manoeuvre.
