Loved the mechanic and the motivation to do a consistent play, and the fact that you don't necessarily need to pay to get a coffee in the case you forget one day, you get coffees when completing days, that's really great, loved it

Best N-Back app out there. It really motivates you to go through the session with their "pay for coffee" trick if you miss your session. I've really seen improved results in my memory and thinking, having completed 12 out of their 20 sessions. Hoping to complete all 20.

Good app, the settings and features have been intricately designed for maximum cognitive results. Aesthetic UI.

Very good app but I've had some problems with this app. At 10 pm it asked me to cash in a coffee which I did but then the next day at 8 when it hasn't even been 12 hours it asked me for coffee. That certainly isn't fair

Very good mental exercise. But I unfortunately the app may be difficult to grant 5 stars due to the coffee punishment still being active after the 20-day challenge. Life is unpredictable and perfection is not ideal, I understand the science of forming habits and having that punishment, but it's just too steep for someone living in a developing country. One would be forced to go premium eventually if not delete the app out of frustration. Sad to have to change apps, but can't afford the premium.

It's asking for donation if we break streak. I tried it. This is too tough. I saw one site dualnback dot Co, it has easy version few boxes only. But this one is too tough. It's hard to even understand and get started. U need to improve this app to make it easiest with the easiest levels as beginners, instead of tough levels in start.

I like using the app, and it actually works, but now im locked out and I tried getting free coffees by sharing but even after my friends download the app and did the tutorial even I did not get to reap the benefits and I am still locked out. I requested for support and now waiting to see what happens.

Had a 70-day streak, then they changed the voices to worse options (without even leaving the previous voice as an option). Uninstalled right away, which hurts because this was a good app.

Description by Rivuspurus Written by the developer, not by AppBrain. Click to read.
The N-Back Challenge provides a special type of cognitive training, “dual n-back,” that helps you raise your IQ in just a few minutes per day. Sounds implausible? The N-Back Challenge is based on a decade’s worth of scientific studies, published in top peer-reviewed journals, including Nature. (For more details, see https://nbackchallenge.com/science.)
The catch? It’s no fun at all! Indeed, the training is designed to be maximally exhausting. If you are determined enough to make it through 20 sessions, however, science suggests that you stand to reap powerful benefits.
Intelligence is the ultimate cognitive ability: You need it to learn, reason, solve novel problems, and see connections. Higher IQs have been linked to improved academic achievement, professional success, and even better health. Since it will take you just 7 hours, in total, to complete the N-Back Challenge, not much more than the length of a single school day, it may prove to be the best investment of time you’ve ever made!
------------------------------
SCIENTIFICALLY SOUND: Not only has the dual n-back paradigm been validated in top peer-reviewed journals, but our two founders – both PhDs, one with a focus on neuroscience, the other with a focus on higher education – have taken particular care to thoroughly align the app with the prevailing scientific research.
TRACK YOUR PROGRESS: In order to help you stay motivated, the N-Back Challenge allows you to visually monitor your progress over time, build up “streaks,” and compare yourself against other learners across various stats.
COMPETE AGAINST YOUR FRIENDS: Perhaps the most powerful way of making sure you remain motivated to complete the Challenge is to tackle it together with friends or colleagues. To make it more fun, we’ve provided leaderboards that allow you to compete based on who has completed the most sessions, racked up the longest streak, and more.
CUSTOMIZE YOUR EXPERIENCE: The N-Back Challenge allows you to choose between different voices across multiple languages, turn on notifications, and customize their timing and style. There are advanced settings for turning on instant button feedback, controlling the n-back level, and tweaking the game speed. And if you are too busy to complete one session every day, you may switch to the Weekly Habit, which gives you a full week to complete each session.
------------------------------
ARE YOU…
… A PARENT? Give your children an edge at school or university by nudging them to complete the N-Back Challenge. Indeed, why not tackle the Challenge together as a family?
… A GRANDCHILD? Help your grandparents (and other older relatives) fight cognitive decline by introducing them to dual n-back. (See https://nbackchallenge.com/decline.)
… A KNOWLEDGE WORKER? Share the N-Back Challenge with your HR department. Dual n-back may well be the single most cost-effective way of making knowledge workers more productive. (See https://nbackchallenge.com/work.)
… A TEACHER? Use dual n-back to enhance students' problem-solving skills. You can have a big impact, with a minimal investment of time! (See https://nbackchallenge.com/class.)
------------------------------
HOW IT WORKS: The N-Back Challenge is free as long as you stick to the program. When you miss or delay a session, we ask you to support us with a “coffee,” which you can buy in-app or earn — for example, by using the Share link in the Settings to invite friends. (Each of you will receive a free coffee.) You can also unlock unlimited free breaks by becoming a premium subscriber.
