Single N-Back

Single N-Back is a game designed to increase your fluid intelligence.
You are shown a sequence of numbers and your task is to click the button if you see that the current number matches the one from N steps earlier in the sequence.

For example, in 2-Back, when you get the sequence

2, 8, 9, 1, 9

you should press the button because the last number 9 is the same as the number shown 2 steps back.

You start with 2-Back, and if you manage to get more than 80% correct, you can unlock the next N-back level.

Have fun!

A few more options would be nice, for example adding and using one's own images instead of numbers. But since it's free, easy to use and does what it's supposed to do (no waiting around, no glitches) still 5 stars. I for my part also like the simple, clear design.

It is awesome! However, please update the application so that all functions work when it is used on newer android versions. I cannot adjust speed nor can I adjust length of the round. Please fix.

I like that it's simple and straightforward. The first few rounds were very good for someone relatively new to N-backs. However, after the first few rounds, each new round begins with "missed", which is distracting and frustrating. I'll try a different app, but will watch this for updates, as I like it otherwise.

Starting with single to move to double, this is exactly what I needed. Not the most visually appealing, but functional structure and options are exactly what I needed.

One of the best n-back apps on android so far

I like the game, actually helps me remember stuff. I am using it on a tablet, so it is a really small square at the top of the screen. Maybe you should play around with different sizes for those people with bigger screens

Nice clean interface and it includes 1 variable n-back (just number, not like number AND color) which I think is the best place to start. The other n-back apps stay out too difficult.
