I would pay a couple bucks for an ad-free option. ### 2/5 — Too many ads *2022-07-18, version 1.3.2* I know there is an option to buy and lose the ads but the free version has an ad running about every twenty seconds. I’d upgrade but none of the buttons, menu items, options etc are complete words on my screen because I wear glasses and have my font set a little higher. Additionally I had my NB set to 1 and even though I remembered 1 back each time it still marked me as incorrect. A bettter version would have held my attention, so to speak. None the less the concept is solid. Would have been 3 stars for app formatting that doesn’t fit screen but the ads sunk it. Any app that spends up to half the usage time running you ads ruins the user experience. ### 3/5 — Ads after every fail every few seconds. Distracting. *2022-04-19, version 1.3.2* It’s difficult to train the brain with long adds you have to wait for every few seconds. Maybe provide a paid version for $1 without the ads because this is madness. ### 2/5 — It’s a shame this is awesome *2022-04-07, version 1.3.2* This app would be so much better without so many ads ### 2/5 — The ads make this app worthless *2021-08-17, version 1.3* I would purchase this app if that would mean no more ads! There is no way anyone can sustain a meaningful workout with an ad popping in every single time you move on to another exercise. Totally defeats the experience! ### 2/5 — To many adds *2021-08-08, version 1.3* I would pay a small one time fee not to have adds. App good-Adds bad. ### 3/5 — Adverts attack *2018-10-06, version 1.2.1* It’s really impossible to play. Please, I’am ready to pay for playing without adverts ### 1/5 — Não entendimento do jogo *2018-05-09, version 1.2* Eu não entendi o jogo ### 1/5 — Ads ads ads *2018-03-13, version 1.2* So many ads and no updates in almost a year. Seems the app was updated one last time to make as much money as possible and the developers moved on to other ventures. ### 3/5 — 広告がない有料版があれば… *2018-01-09, version 1.2* トレーニングそのものの内容は満足度高いですが、毎回広告で待たされるのが、テンポが崩されて困りますね。 機内モードにして起動すればいいんですが、手間ですし、広告なしの有料版が欲しいです。 ### 2/5 — Too many ads *2017-12-30, version 1.2* I used to play this for myself, now I came back to play with my son and we get ads between every reset, this is ruining the app experience ### 1/5 — Absolutely ruined the app with this update! *2017-12-08* Don’t waste your time or coin on this. This is a prime example of a developer upgrading an app to a poorer state, and then adding the most annoying advertising on it. Good thing you mucked the app up, otherwise I’d probably pay for it... Should have left the buttons as you had before! I used to use it all the time - now I’ll never go near it again. Nice one champ! ### 1/5 — The Ads ruin it. *2017-11-25, version 1.2* Developer needs to rethink this ads strategy. ## Most critical reviews (10 lowest-rated) ### 1/5 — Trash *2025-06-24, version 1.3.2* Trash app, lot of ads ### 1/5 — Ad after ad after ad *2025-04-25, version 1.3.2* This app has too many ads that gone on far too long to bother with. You play a round and then you have to sit through a stupid ad before you can play another round. You spend more time looking at ads than playing the n-back game. I deleted this app about eight years ago because of this. I had forgotten about the waste-of-my-time ads. Don't waste your time with this app. ### 1/5 — Ad after ad after ad *2025-03-03, version 1.3.2* This app has too many ads that gone on far too long to bother with. You play a round and then you have to sit through a stupid ad that before you can play another round. You spend more time looking at ads than playing the n-back game. I deleted this app about eight years ago because of this. I had forgotten about the waste-of-my-time ads. Don't waste your time with this app. ### 1/5 — 非常差劲 *2024-03-15, version 1.3.2* 里面的功能根本没法用，估计就是为了赚广告费 ### 1/5 — N adverts back *2021-04-22, version 1.3* It was my favorite app for mind games for a long time. However, an advertisement level for is out of any borders. 2 adverts 5 seconds each. Serious? Nedda be mental or extremely persistent to continue to use this app. Moreover, you have no option to pay some money and get a version without advertising. The way this app has turned is flipping me out. Deleted. ### 1/5 — 広告うざすぎる *2020-11-08, version 1.3* だるいのでもうやる気起きませんね、このアプリは終わった ### 1/5 — Too Many Ads *2019-10-08, version 1.2.1* Used to be a great app for concentration, now it is loaded with so many ads it’s garbage. ### 1/5 — Ads are so distracting, it makes this app worthless *2019-09-27, version 1.2.1* This app was recommended by my mental rehab therapist after a massive heart attack. However, the ads are so distracting that I lose focus after each round and lose the benefit of the app. Not helpful at all. ### 1/5 — 10秒のゲームの度に5秒以上の広告 *2019-06-13, version 1.2.1* 一回一回がゲームが短いのに、広告が毎回長い。時間がもったいなすぎるので早々にやめました。 ### 1/5 — 不愉快 *2019-02-21, version 1.2.1* 広告多すぎる ## Most praised reviews (10 highest-rated) ### 5/5 — IT WORKS *2025-02-13, version 1.3.2* Playing this has improved my memory and fluid intelligence. It helps me with many things including being able to keep my track of thoughts. My ability to remember what a person said while still listening to them and being able to reply to what they said prior in the conversation as well as currently so I don’t have to try so hard not to forget key points in the conversation that I want to discuss further. You should do it 15-20 minutes a day. There is not a doubt in my mind that I am cognitively performing in many aspects at a higher level than before. Consistency is key. It might seem hard at first and the ads pop up too often but none the less, N-back works. Thorough studies have been done that show similar results between single N-back and dual N-back. The only thing about this app is there are too many ads, but it’s worth the setback. ### 5/5 — Too many ads *2025-01-25, version 1.3.2* Stop with ads after every game I play 3 back often and it lasts 4 seconds and then there is an ad after each game. My name is MikeMcFarland81 and I’m ranked very high on the level 3-back but because I’m so fast I see ads every few seconds literally. ### 5/5 — Мне нравится *2023-05-18, version 1.3.2* Гениально! Но почему-то 11 равно 1 ### 5/5 — Need skip button when forgot something *2021-12-20, version 1.3.2* and sometimes answer text disappears. ### 5/5 — Great app *2021-10-14, version 1.3.2* Keeps my working memory in good working order. ### 5/5 — シンプルで素晴らしい *2020-09-29, version 1.3* 単純な計算と暗記のみ。 シンプルでとても使いやすいです。 広告はネットワークを遮断すると表示されなくなります。 ### 5/5 — I LOVE IT *2018-06-21, version 1.2* I don’t know about the research. It just feels good to exercise my brain this way. Based on pure intuition this game is grand:) ### 5/5 — Adv!!! *2017-03-27, version 1.2* Too much advertising after updating. Delete please or have to delete app ### 5/5 — シンプルで扱いやすい *2016-12-29, version 1.1.2* 無料だし、使いやすいデザインだし、10-backまで無料で対応しているので、文句なしです。他にもN-backアプリを複数ダウンロードしましたが、メインはこのアプリを使ってます。 ### 5/5 — Непонятно *2015-05-12, version 1.1.2* Извините,не подскажите как играть в эту игру?Не могу разобраться хотя понял какое это супер приложение --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
