Dual N-Back: Stroop & Schulte downloads
Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.
Active users
All platforms, worldwide. Free with an account.
Stickiness (DAU / MAU)
how many monthly users open it on a given day
How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.

Review momentum
20/100
faster than 0% of Education apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About Dual N-Back: Stroop & Schulte
Dual N-Back is a working memory training app for adults who want a real mental workout on iPhone. Train the classic n-back task from N-1 to N-15, with up to seven simultaneous streams, plus 12 cognitive tests including Stroop, the Schulte table and the chimp test.
PRO REQUIRED
A subscription or a one-time lifetime purchase is required to use Dual N-Back after the welcome. The yearly plan includes a 7-day free trial for eligible accounts. The welcome and a practice round are free. If you were already using the free version on this device before version 3.8.26, nothing changes for you.
HOW IT WORKS
Two streams arrive at the same time: a position on a grid and a spoken letter. You answer when either one matches what appeared N turns earlier. You start at N-1. Reach at least 80% accuracy on every stream at your highest unlocked level and the next one opens. It is hard on purpose, and that is the point.
A PLAN BUILT FROM YOUR ANSWERS
Tell the app your goal, your daily time and your experience. You get a personal 7-day plan, a starting level, a session length and a reminder at the time you choose.
UP TO SEVEN SIMULTANEOUS STREAMS
• Dual — position + audio
• Triple — colour joins
• Quad — then shape
• Penta, Hexa, Hepta — up to seven streams at once
Levels N-1 through N-15.
THE COGNITIVE LAB
Twelve short tests: Stroop, Schulte table, chimp memory, reaction time, visual, verbal, number and sequence memory, aim trainer, typing, mental rotation and rule switching. Each keeps your best score.
YOUR NUMBERS, NOT BADGES
Progress per level, accuracy broken out per stream, average reaction time, streaks. You see where you stall, not just a score.
DUAL N-BACK PRO
• Every level, up to N-15
• Dual, Triple, Quad, Penta, Hexa, Hepta
• Unlimited daily sessions
• Full analytics
• Custom Mode and Free Mode
A 7-day free trial is available on the yearly plan for eligible accounts. The offer and the subsequent price are shown before purchase. Lifetime available as a single payment, with nothing to renew.
WHAT THE RESEARCH SAYS
The dual n-back task has been used in working memory research since 2008 (Jaeggi et al., PNAS). Researchers still debate how far the gains transfer beyond the task (Au et al., 2015; Melby-Lervåg & Hulme, 2013). What you can measure here is your own progress on the task, and it's on screen.
SUBSCRIPTION
Payment is charged to your Apple account at confirmation. Renewal is automatic unless turned off at least 24 hours before the current period ends. Manage it any time in your account settings.
PRIVACY
Training history stays on your iPhone, with iCloud sync through your Apple Account when available. No app account to create, no third-party ads, no ad tracking.
