An easy stand-alone quizzing application.


iQuiz is based on the idea of learning a certain subject with cards having questions on the front side and answers on the back side. iQuiz does this electronically now! Launch iQuiz, select an imported theme or create a theme by yourself, and quiz your knowledge...

Themes and questions can be created, updated, deleted, as well as exported or imported. During a quiz, all correct and wrong answers are logged and memorized. Thereafter, e.g. all difficult questions can be redone again, or specially marked (e.g. important, always to be know) questions repeated. Themes can be printed out, or saved as PDFs (e.g. to load onto your iPhone).

Cool tools for your desktop or laptop, for learning or calculating, for gaming and more... all programs written with Xojo (RealBasic).
