FAQ

Common
questions.

What is Number Learn Studio?

An interactive web application for memorising mathematical constants like Pi, Euler’s number, and the Golden Ratio. It provides a VS Code‑style workspace with multiple learning tools side by side.

What is the Major System?

A phonetic mnemonic technique that converts digits into consonant sounds, which you then form into memorable words. For example, 1-4-1-5 becomes “turtle”. It’s used by memory champions worldwide.

Which constants are available?

Over 17 built-in constants including Pi, Euler’s number, the Golden Ratio, √2, Euler–Mascheroni, Avogadro’s number, the speed of light, Planck’s constant, and more. You can also add your own custom numbers with up to 1,000 digits.

Can I add my own numbers?

Absolutely. You can paste or type any number up to 1,000 digits long. Custom numbers appear in your sidebar alongside the built-in constants.

How does progress tracking work?

Your progress is saved locally and synced to the cloud when you sign in. We track digits learnt, accuracy, speed (digits per minute), streaks, and achievements.

What panel types are there?

Fourteen: digit display, recall test, typing practice, chunk trainer, sequence, canvas, notes, scratchpad, timeline, progress, statistics, Major System helper, Piem generator, and achievements.

Does it work on mobile?

The studio is optimised for desktop with keyboard shortcuts and split panels. The landing page and basic features work on mobile, but the full studio experience is best on a larger screen.
