Mantiq

Mantiq (منطق) is the Arabic word for logic. It trains the faculties a modern mind lets atrophy: holding things in your head, reasoning with numbers without reaching for a screen, knowing how sure you actually are, and noticing what is in front of you.

One short sitting a day runs four disciplines — memory, calculation, calibration, observation. You advance through five ranks by passing timed trials, attemptable once a day. The app tells you plainly how you did, then lets you go. No streaks that punish you, no confetti, no re-engagement nudges.

One-time purchase, no subscriptions, no ads. Your first sitting is free. Your data never leaves your phone.
