Flawed algorithm

Unfortunately the app doesnโ€™t allow you to pass onto 3-back before paying. I did make the mistake of paying and found out that the algorithm is flawed. Apparently once a square lights up, the chances of it activating again are much bigger than 1/9, which makes the experience so much worse.

Really Good Product, Known to Work, Needs* Subscription

First of all, N-Back wasnโ€™t created by this app and its developers, it was made by some scientists who were trying to measure short-term memory an attention. Second, this team proved that the N-Back test can improve short-term memory and focus through repeated tests. Third and finally, while this app is free, it only goes up to the second level, limiting how far you can improve.

Oddโ€ฆ

It said that I reached level 3 (the max on the free tier) even though I never played it lol

Poor functionality and statistics

Love the game, but every-time I accidentally slightly miss a button, it stops the game. Very frustrating. Also the user statistics is just not really helpful at all

Great game

Thanks for the level-up

Thanks for the free version

ad free & works

Subscription based

subscription based way to play your mobile game for memory is crazy kick rocks

No E-Mail Reply From Developer

I upgraded to the Pro Version but the app still says I need to upgrade. I really like the app, but for me to be able to benefit from it, I need some of the pro features. I emailed the developer twice for help but never received a reply.

Trash

No explanation no information about how to actually play and use the app. Terrible app

Feedback

Overall great app thatโ€™s highly configurable. There seems to be a bug: if you decrease the time to the max and the interval speed the final score/feedback doesnโ€™t account for these settings. Also, itโ€™d be great if something like a check mark or โ€œXโ€ were used for when screens are set to greyscale (maybe even for colorblindness?).

Effective Mental Exercise

This app is a useful tool for training memory and mental processing speed although it is definitely frustrating and difficult at first.

Sucks

Not user friendly. Makes it sound like itโ€™s the most simple thing in the world, then I canโ€™t seem to do anything when the game begins. Garbage

Buggy

The app does not seem to correctly register the clicks I make. Usually 1-2 times per round it indicates Iโ€™ve clicked position or sound and I have not. Even if itโ€™s N=1 and I know the answer is not correct.

Only 2 levels for fee

Says level 3 is the maximum for the free tier, but it actually wonโ€™t allow you to play level 3. A monthly sub to go higher than 2 is kind of crazy.

Stop button too easy to hit

An otherwise well-designed app is fatally flawed with a stop button in the middle of the screen thatโ€™s too easy to hit accidentally, suddenly and frustratingingly ending an attempt. Either add a confirmation or move the button to a top corner.

Locked behind a paywall

Itโ€™s a good interface until you reach level four, which is locked behind a paywall. Levels two and three are very good, but considering there are so many free apps that do the same thing itโ€™s just not worth it.

Itโ€™s great! Justโ€ฆ

I just wish I was able to increase the length up to 30mins! From what I can tell, most efficacy was found in this time range in studies. Increases the challenge. Obviously you can do lots of little 2min sessions. But would be cool to do continuous. But great app otherwise, thanks so much! Ad-free, it seems :) ๐Ÿ™
