Memorise ln 2 with muscle memory

PlayMemorize is a tool for memorising ln 2 (ln2 ≈ 0....). It uses the Major Pincode System: each group of six digits becomes one numpad shape your fingers learn, and one three-image story your mind holds. The shape and the story are locked together from the first tap. Enable sound to add a third anchor: each digit plays a unique musical tone.

It works on any device, but performs best on a phone. With enough repetition, the digits become a sequence of movements rather than numbers.
