## What is nBack+?

nBack is a game designed to improve working memory and fluid intelligence. nBack is a game where the user is required to remember a sequence of values and to determine whether element m is a match to element m-n. For example, if the app calls "A", then "B" and finally "A", this would be a match in 2-back as the second "A" matches the "A" called two prior.

nBack comes with standard n-back functionality with some extra customization. You can play on a grid varying from 1x1 to 6x6. You can select between single, dual or tri n-back variants. And, of course, you can vary the n to difficulty. There are also a few other customizations.

## Key features

- Working memory training

### 4/5 — Best customizable n back

*2022-04-23*

theres problem with the history though and the last game results dont update quick enough

### 1/5 — No instructions

*2021-09-28*

No instructions. I played how I guessed it much get have worked (I did the colts and tapped the screen if I thought the color shown two views before matched), but at the end of each game it said I got 15 correct and 0 incorrect, even when I purposefully chose incorrectly. Useless!

### 1/5 — No sounds

*2021-07-08*

Theres no sound

### 4/5 — First impressions

*2021-06-21*

I’m cautiously optimistic about this app. The history doesn’t seem to be working and it would be nice if the results showed a breakdown of correct/incorrect answers for space, colour and numbers, but apart from these little issues it works well.

### 1/5 — Not user friendly, not accessible to novices

*2021-01-27*

There is no demo mode, there are no instructions. I have played other n-back games and I don’t understand how this one works.

### 5/5 — Best NBack

*2020-12-31*

Best in dual n back game in App Store. I also like it for the customization, and because it’s free.

### 5/5 — Great n-back game

*2016-11-07*

I really like the customization over most other n-back games in the app store.
