No illustrations
The exam has images of situations and signs, the app just describes them but never show any.
Response from developer
You were right, and thank you for flagging it. Version 1.2.0 (just released) now shows the actual Japanese road signs and top-down situational diagrams on those questions, instead of only describing them in text. If you get a chance to take another look, we'd love to hear what you think — your feedback made the app better.
