What’s New Version 1.13.3
This version contains a few bug fixes and technical improvements.
Thank you for using our app.
Description
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.
CUSTOMER SUPPORT: Do you have any questions or suggestions? Like to say hello? We’re happy to hear from you! Just drop us a note at support@nbackchallenge.com.

Build 880216374v1.12.02025-12-03 11:28:06
In this version, we applied a major upgrade to our voices across all supported languages. Not only do the new voices sound more natural and pleasant, but they should also make it much easier to phonetically distinguish the different letters being read out.
At the same time, we fixed a bug related to missing stimuli during gameplay.
We hope these updates improve your enjoyment of the N-Back Challenge. Thank you very much for using our app!
Build 877416713v1.11.02025-08-21 12:30:30
This update includes behind-the-scenes improvements to keep coffee referrals working as expected.
Thanks for your continued support and feedback!
Build 876076179v1.10.02025-07-07 11:28:50

Build 870297549v1.8.32024-11-12 07:09:59
In this update, we've fine-tuned the subscription purchase experience to make it easier to choose between our monthly and annual subscription plan.
Build 869826159v1.8.22024-11-05 10:25:20
Besides a few bug fixes, this update includes our new premium subscriptions, which give you access to unlimited free breaks, the Weekly Habit, and our level leaderboards. At the same time, we are retiring our "pizzas." You can still purchase "coffees," though, which, as before, you can cash in to take a break and, if you've broken a long streak, to repair it.
Build 859572140v1.6.02023-08-31 20:48:59
Fixed a handful of bugs, mostly related to voice selection.
Build 857935125v1.5.02023-06-19 20:53:57
A recent iOS update, 16.5, seems to have caused issues for a few text-to-speech voices. As a result, we have temporarily removed some of the voice options and languages (e.g., German).
Build 856821006v1.4.22023-05-03 15:49:32
A recent iOS update, 16.4.1, seems to have caused issues for some text-to-speech voices. Apple responded by quickly releasing an automatic update, 16.4.1 (a), that should have fixed these problems. This version of the N-Back Challenge includes a modal with information about this issue, as well as a free coffee for those who may have delayed or missed a session as a result of voice-related problems.
Build 856136781v1.4.02023-04-05 21:14:22
Fixed a few minor bugs.
Build 855034652v1.3.02023-02-19 01:55:25
For those in our community of learners who have experienced data loss issues in version 1.1.2 of the N-Back Challenge, this version is meant to restore your missing data. We're also giving out another free coffee, just in case any of you have taken a break from the N-Back Challenge since version 1.1.2 and are now being asked for a coffee upon returning.
If anything seems to have gone wrong with the restorage of your data, please don't hesitate to reach out to us at support@nbackchallenge.com. Thank you very much for bearing with us, and apologies again for the inconvenience the bug from version 1.1.2 has caused!
Build 854773589v1.2.02023-02-04 23:30:17
Version 1.1.2 of the N-Back Challenge contained a bug that may have cut some of your data, including your coffee balance and game stats. The purpose of this release is to prevent any data loss, going forward, for those who had not yet been affected by this bug. As for those who have already experienced problems related to this bug: We are currently working to restore your data from the back-ups on our servers. We sincerely apologize again for the inconvenience the temporary loss of data has caused you. If you have any questions, please don't hesitate to reach out to us at any moment via support@nbackchallenge.com.
Build 854708282v1.1.32023-02-02 23:27:21
The latest version of N-Back Challenge contained a bug that may have cut some of your data, including your coffee balance and game stats. The purpose of this release is to reassure you that your data are backed up on our servers, and that you will see them restored in our next app update. This new build also contains a gift of 4 free coffees. We are working hard to release the new version as soon as possible, and we sincerely apologize for the inconvenience!
Build 854689261v1.1.22023-01-31 18:24:53
Following the latest iOS release, some of our learners reported problems with non-English voices. This version contains fixes to address the main issues. Unfortunately, the non-English voices supported in this version do not sound quite as natural as some of the previous non-English voices. We hope that we will be able to make high-quality non-English voices available again in the future. For now, you might want to consider switching to English voices instead.
Please also note that, following the latest iOS release, the English voices seem to take longer to initialize, which can lead to problems at very high (e.g., 4x) playback speeds. Here, too, we hope that this will only be a temporary problem.
Kudos to our community for alerting us to these issues!
Build 853146395v1.1.02022-11-03 22:49:25
