Magic No 7 app for iPhone and iPad

Magic 7 app aims to test capacity of your working memory. You will find out what is the maximum number of items that you can recall without mistakes. The whole idea is based on Millers Law.


This application was developed as part of my BSc thesis „Mobile solution of system testing Magic number 7”.


Data collected by this app includes information about presented sequence of geometric figures as well as education, age and gender, voluntarily provided by user. None of this data is trackable to individual user nor device and is collected purely for scientific research.
