Perfect. The tutorial, relax mode, challenge with timer - it has everything you need to practise and master Abacus. Extremely grateful for this app. Kudos to the developers.

Learning the precious Abacus is yet very serious business in modern Mathematics, because of the unanticipated preeminence of the Hexadecimal or Sexadecimal Base discernment. The profound Base 16 is now understood as the gold standard modulus, along with the primordial Binary, for future calculation and expression in language. The Japanese Soroban I fancy, to show respect to Japanese intellectuals, and to calculate before their Emperor if ever summoned, in order to limit any of their contempts.
