I created NeuroCalT+ Mental Math to help me practice the Trachtenberg system of mental calculation.

The idea is simple: this app is not designed to teach you the entire Trachtenberg system or turn you into a fast calculator overnight. It is primarily a practice tool, with explanations of the methods to help you understand how they work.

I don't always have time to follow the app's progress or see how people are using it. Life gets busy, and sometimes side projects have to wait.

But it's always a pleasure to open Google Play Console and discover that someone has installed the app or found it useful. Even a few downloads are a nice reminder that something you created for yourself might help someone else, too.

Thank you to everyone who has given it a try!

Sometimes, the best part of building something isn't watching the numbers grow — it's knowing that someone out there might find your work useful.
