Do you think an abacus is a completely indecipherable alien object? Do you pretend to have aphasia when someone asks you the time and you only have an analog watch handy? Did Roman numerals make you think that the last cathedral you visited was built in the year 2563? Do you always pay by card even though your wallet is full because you once caused a queue at the checkout that went around the building three times?

Never again! Learn to automate these tasks with Eucalculia! Free up your mental capacity and focus on your existential angst!

What is Eucalculia?

Eucalculia is an evidence-based training app designed to strengthen number sense—the intuitive understanding of quantities and their relationships. It can help people with dyscalculia and anyone wanting to improve their mathematical fluency

Research shows that response time (RT) under 300ms indicates true subitizing—instant quantity recognition without counting. This app trains you to extend that automatic recognition.

I have made it available here completely free of charge: https://edefakiel.github.io/Eucalculia/eucalculia_2.3.1.html

It is extremely important to read the guide first.

Have fun!

Fixed issues with roman numerals, dice, dominoes, etc.
Now you can keep playing a new block by just pressing the space bar.

Just used your app for the first time. This is fantastic work. I will definitely continue using this, going forward.
