IQ – quiz for iOS

A helper app for learning important topics in iOS development.
Questions in the following sections are already available:
- Multithreading.
- Algorithms.
- Memory.
- Architectures.
- Code.
- Compiler.
There is an opportunity to pass not only topics, but also to try yourself in different modes: struggle with time (the most answers in a given period) and hardcore mode until the first mistake.
Also added statistics and there are leaderboards (you can add your nickname if you want).
In the settings, there's a way to make it easier to pass, add question sorting and choose the size of the quiz.
