Fun Multiplication Table

Our client wanted to build an app that would help kids learn the multiplication table, yet there were no clear defined requirements for how the final version should look like.

We applied agile software development principles and focused on making a flexible architecture that allows in no time reorganize example patterns, generate levels and game modes.

The application runs completely offline while containing about 2000 images and more than 150 audio tracks. In order to reduce the data size we split similar images with different colors into layers, so instead of 2000 images we had only 700 layers that were automatically converted into complete images. We managed to find a way to turn vector drawings, that are not supported by iOS, into bitmap with little to no quality loss.

The app collects data about child’s performance: number of wrong and correct answers, time spent on completion etc.  Since the app had to run offline we developed a module for background synchronization with the server. Once connected to the internet all the data is automatically synchronised.

In a free trial version of the app only first few levels are available the rest could be accessed after purchasing the full app.

Ultimately, our client received a mobile application that conformed to all of their requirements and which size was reduced by three times. Kids got an entertaining app that helps them learn and parents got a tool to track their progress.
