Good content, difficult to navigate

Whilst the information is accurate and detailed, the layout is a bit haphazard. Perhaps I'm not the target user for this app: I don't use this while navigating, I just thought it might make a suitable replacement for various reference books. It does, to an extent, but it's not complete enough for me. Why are some Rules present and others not? It just feels like an introduction to lights and signals, and I can't help but feel that something's missing.

Not updated.

Considering the price of this app I was surprised to get a message flag up about it which said the application will not be compatible with future versions of IOS and may slow down my phone unless the developer updates the software.

Developer Response ,

Hello, we are working on an upgrade for iOS11 compatibility and it will be released soon. Regards, Imray Support team

Sounds don’t play

Happy with this app except sounds do not play at all? I’ve checked settings & reloaded app but still do not work, which is a pain.
