### 5/5 — Good app

*2026-06-05*

spent ages trying to find a good n back game without having to pay for a subscription. Most free ones had issues. This app is well made and works perfectly, definitely worth 99p, would recommend

### 5/5 — Best Dual-N-Back app

*2026-04-01*

Best app for cognitive training. One small request: add a dark mode app icon, and it will be perfect.

### 5/5 — Great game

*2025-11-13*

Great game. Glad I took a punt on buying this game, as offers N=1 which many of the other apps don’t have. My suggestions to improve the app are as followed: 1) have a way of contacting the developer to suggest feedback within the app 2) I would like to see a clock timer to have the option to play for 30 seconds, 1 mins, 1.5 minutes per game to test my mental stamina instead of 21 rounds per trial game 3) I’d like to hear sounds when I’m tapping the position or letter buttons to make it more interactive (perhaps users could turn this on and off if they don’t like to hear sounds).

### 5/5 — Very Good App

*2025-11-12*

High quality app and costs less then a dollar!

### 5/5 — Get this one!

*2025-10-10*

I tested 5 other apps before I found this one. 
This one is perfect, good sounds, good visuals.
And the history feature is awesome!

I was so frustrated with the other apps to the point I almost made my own. 
Glad I found this one. 
From one dev to another: great work! 👍

### 5/5 — Good App

*2025-06-15*

Best $0.99 I spent all week.

### 4/5 — Best overall NBack app on iOS

*2025-06-15*

Gives great stats at the end of each round. However, would be good if the “feedback” option provided feedback in both the case when you miss a match and when you make an incorrect attempt to match.

### 1/5 — Doesn’t work

*2025-06-12*

Does not provide feedback if you don’t make attempt when you should have.

### 5/5 — The best Dual-N-Back game ever

*2025-04-10*

This is by far the best dual n back app I’ve come across. The design is sleek, intuitive, and incredibly user friendly. It makes training both enjoyable and effective. I highly recommend it. 

Huge kudos to the developers, fantastic work!

### 5/5 — Very high quality

*2025-04-09*

I took a gamble and bought it since the other N back apps were kinda mid - this one is great, feels premium and there’s history (idk if ill ever use it though). Also has real voice which is what prompted me to review it (not robot voice)
