  ¿Qué hay de nuevo en la versión 3.0.3

  Actualizado el 13/08/2026

  Version 3.0.3:
  
  • Matrices and Paper Folding: new point scoring. It counts how hard the solved items were, not just how many. Earlier results keep their percentages.
  • Form Focus: wrong answers are now subtracted, so guessing no longer scores. The pace adapts more reliably. Your previous Form Focus results are removed once in this update.
  • Training mode: the timer now runs correctly for the duration you pick.

  New module d-Test: train selective attention and concentration under time pressure, inspired by the methodology of the d2-R. 14 lines with 56 characters each, 20 seconds per line.

Concentration performance (KL) feeds the scoreboard and leaderboard.
