Extreme Concentration Trainer

• Choose from 12 interface languages and set your training alphabet separately. For example, keep the menus in English while practicing Greek or Ukrainian letters. • Practice with letters, digits 0–9, or a mix of both. Choose uppercase, lowercase, or mixed case for alphabets that support it. • Try exercises with symbols, dot circles, or Bourdon groups of two to seven dots. • Start a session from the redesigned Home screen. Larger target buttons and a full-width Space button make two-thumb practice easier. If you switch apps, the timer pauses and your place is saved. • See separate counts and percentages for correct selections, missed targets, and wrong selections. Track your practice with a training calendar and total active training time.
