Dual N User Reviews

Top reviews

I had to leave a review

This is a way of life, and if you take it seriously, it can improve your memory. I didn’t realize some people were upset that it doesn’t have a grid, but it didn’t bother me. In fact, I found out that people said it to be more challenging without one, which I think is a good thing. Overall, this app is something I plan to use for the rest of my life.

Scoring doesn’t make sense

If I never submit an answer I automatically get 70%? I just want to see how many I missed vs how many were possible. Percentage of success in the scoring is vague and doesn’t make sense since apparently if I don’t hit the buttons when there isn’t a match that’s correct too?

Maybe add a feature to pick how you want to be scored. One for the current way and another for showing how many matches were possible vs how many you hit and then how many errors you made.

English Version

Is there a version that uses Zed as opposed to Zee.

The only N-Back app that I like

Really great, simple Dual N-Back app I’ve found that is well-made, nice looking, and functional. And I’ve tried every single one with 3+ stars. Unlike another reviewer, I like the grid-less layout — an extra challenge.

The ads on the free version are not obtrusive at all but I still paid $1.99 to support the developer.

Currently my favourite app

This is currently my favourite app! I’ve been practising several times every day. Thank you for a clear, neat experience of N-back, better presented than the other ones (I went and tried most of them). If there was Tri-back or Quad-back options available it would be even better.

Difficult without the Grid

Lean into the difficulty. I like that it doesn’t have a grid. It didn’t in the beginning like more other reviewers. However, after playing it a while, it makes you even better at the game. It challenges your brain more, and that’s the point. So lean into the difficulty. I’ve only made it to N9, currently stuck on 7/8, but motivated to go further. I can literally feel my brain working. This has to be good for you. I also feel I have some clairvoyance from time to time.

Grid!

It’s a great app but at the very least, there should be an option to turn the grid on or off. I’m just starting out and not having a grid for me is distracting and makes it tougher to memorize.

Position and Sound Buttons come up too late.

I have good things from Mr. Greenfield of Boundless fame. The game is touted as something that improves cognition and memory; however, it is only “improving” my exasperation with the sound and locations buttons not coming up simultaneously to the game beginning. I would stay away until this glitch is resolved and stick to the other N-back games. They seem to not have this glitch about them and are quite challenging.

Good app for concentration

I can’t tell you whether my IQ is actually improving, but this is a great way to start a workday or study session. Do 10-20 of these and you are laser-focused and ready to perform.

Just a recommendation for the app developer to do some spell-checking. E.g make sure the word “exercise” is spelled correctly. Little things like that detract from what is otherwise a really well-made app.

Need option to swap button

Great app ! Hope to have option to swap two button

Challenging, fun

I love this app, helps me stay focused.

Best of two

I tried another that was really spammy and I appreciate that this one is not like that.

One question I have is if players are penalized for false positives? The other one I tried showed errors in terms of misses and false positives. Not sure if this one does because I’m only told “how many I got right”

One issue is that some letters come out consistently wrong, to the point where I’m not sure what the letter is. The behavior is that I hear a short clipped sound from the left and the end part of the letter from the right. Using headphones, not sure of that has something to do with it...

Thanks for the app!

Dark background worthless in bright room

Overall the app is good, especially with new voice. That said, there are issues that should be fixed:

- The dark background makes any reflected light incredibly distracting (please add a light theme)
- While the new voice is good, this app still uses portly planned combinations of letter that sound like each other (e.g. z, c, d, t...)

It would also be nice to have the option to reset stats.

Unusable

The 3x3 box is not visible. Is this a feature? It is not in the original spec and this issue was reported a year ago. Refund NOW!

Could use a session tally

Great app! Would love a graph or tally of some kind of how many sessions have been complete throughout a day.

No sound starting today

Was a very good game until today. No sound. Not able to play any more.
Please fix.

Needs to use phone speakers

Have to use headphones which makes it inconvenient because I don’t usually have them.

Pointless

Can't distinguish between the letters that rhyme with each other. Deleted.

Why no grid??

On an iPad pro (12.9 inch screen) the small pastel squares on a dark background just get lost. Not sure why the developer can't respond to the multiple requests to add a grid, but there are better dual n-back apps available.

No audio

Looks interesting. Clean UI, however unusable as no audio is present in my build
