n-back review
A focused Android app for adaptive dual n-back practice and progress tracking.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
n-back is a mobile working-memory trainer built around simultaneous visual-position and audio-letter exercises. In each exercise, users identify whether either stream matches what appeared or sounded a set number of rounds earlier. Its narrow focus suits Android users who want straightforward n-back practice with progress tracking, rather than a broad collection of brain-training activities. The app is described as free and open source, and its maker says it has no ads, tracking, or accounts.
The training loop combines adaptive difficulty with practice and scored sessions. Levels increase as accuracy holds, while practice mode is kept separate from scored work. During sessions, users can adjust position and audio controls. This makes the app a fit for people interested specifically in dual n-back and gradual difficulty changes; it is less suited to anyone seeking varied exercise types or a wider training curriculum.
Progress tracking covers average accuracy, total sessions, a seven-day accuracy trend, and activity history, alongside training streaks, user level, and XP. Those signals offer a compact record of practice and performance without expanding beyond the core exercise. Its mobile scope is limited to Android, so people looking for cross-platform access should consider another option. Choose n-back for a focused, free dual n-back routine and simple tracking; look elsewhere if variety or broader platform coverage matters more than that single exercise focus.
