Best N-back

Best N-back app for iOS 100%

Response from developer

Thank you so much for the 100% rating ! Knowing that you consider this the best N-back app on iOS truly means the world to me. Wish you the best on your brain training journey!

Almost great

The best n back app I have tried out of like 5. I haven’t been using long, about a week, and have only unlocked quad n back.

It is feature rich and seems to be completely free as advertised. I would rate it 5 stars but have come across one issue and one missing feature so far holding it back.

The triple n back mode that utilizes color, one of the colors is red and one is pink, among others like green, blue, purple, yellow. The red and pink are way too similar. I’m not sure how this made it in to be honest. The test is about memory, not discerning colors. Use white or orange or anything that isn’t so close.

Also, it should allow mixing and matching variables. Let me play triple mode but with position, audio, and shape, instead of color. Also, having color as the third mode as it stands makes it so color blind people are at a disadvantage. I see no benefit to having the modes locked as they are currently.

Love the app and looking forward to updates and improvements.

Response from developer

Thank you so much for this thoughtful and detailed review it genuinely means a lot, especially coming from someone who’s tried several other n-back apps. You’re absolutely right on both points. The red/pink similarity is a fair catch: memory training shouldn’t turn into a color-discrimination test, and it puts colorblind users at a disadvantage. I’ll be swapping those for more distinct, accessible colors. And your idea about mixing and matching modes is spot-on letting you build your own combinations (position + audio + shape, for example) instead of locking them makes the app far more flexible, and there’s really no good reason to keep them fixed. Both of these are coming in the next update. Thanks again for taking the time to help make the app better reviews like yours are exactly what push it forward. 🙏

9.8/10 best n-back game

After playing literally all the n-back games on the App Store this is truly the best one made. Will there ever be a Game Center/leaderboard integration? Would love to compare stats with my friends.

Apart from the social aspect it would greatly enhance the game if there was a daily game tracker for streaks for accomplishing certain daily goals

Response from developer

Thank you this genuinely means a lot. Knowing you've tried every N-Back app out there and still call this the best is the highest compliment I could ask for. Good news on both fronts: Game Center is arriving in the very next update. You'll get global leaderboards, the ability to compare your stats with friends, an XP system with 15 ranks to climb, unlockable achievements, and a unified Brain Score that captures your overall cognitive progress in a single number. You also called the roadmap perfectly that same update introduces daily streak tracking (with a 7-day view so you never break your chain), plus Home Screen and Lock Screen widgets that surface your streak, rank and Brain Score at a glance to keep the daily habit going. Deeper daily goals are next on my list. It's built and already in review with Apple, so it should be live very soon. Thank you for taking the time to write this and for helping shape where the app goes next feedback like yours is exactly what I build for. - Roméo, creator of Dual N Back
