Sharing dualnback.com — Feedback Welcome

[Allen W]

Hey all. I've been meaning to share my project at https://dualnback.com with you all here for some time. I think I've built a pretty unique and effective way to dual n-back and I hope some of you will enjoy the new format.

The system is made to automatically adjust 7 different variables to increase or decrease the difficulty within an n-back level. The intention is to prepare you as much as possible for the next n-back level before making the leap.

Most apps (if not all) make you jump back and forth between n-back levels. IMO this is too abrupt. It can be extremely taxing on the brain, resulting in most people quitting before they make any real progress.

For example, here is how the parameters automatically adjust between 4.25 and 4.80:

As you continue from session to session, the system will automatically suggest the next difficulty level. So you might hover somewhere between 4.25-4.75 for a while, for example, until you experience a breakthrough. Once you reach 4.50, for example, it will provide an option to skip to 5.0, or you can choose to go all the way to 4.99 first.

You can also manually adjust the difficulty level as needed:

There is also an assessment tool available called Counting Span Task (CST), which allows you to measure your working memory on a monthly basis. I intend to add Operation Span and Reading Span tests in the future.

Free accounts get access to 10 sessions per day along with the abilty to measure your working memory on a monthly basis with the Counting Span Task (CST). I figured this would be enough for 90%+ of individuals and is enough sessions to build a daily habit.

I'm working to add the following new features:

• Classic mode - default settings based on research protocols (Jaeggi) which can be manually adjusted.

• Android/Apple app

• Quad n-back (adaptive and classic mode)

My goal with with this website is to make the game both more accessible and effective by reducing the difficulty in transitioning between each n-level. 

I also invested a good amount of time into building a quality beginner tutorial to hopefully help introduce and get more people n-backing!

I would love to get your feedback!

Tbh pretty cool, nice dashboard too, very pro! I would make it more "flow" > less counters, make it quicker to just start a session. Also start training free button isnt working on my laptop, had to use google login; I think thats where most people dropped off. Also not sure if I would paywall the number of sessions (10), most people here are looking for more sessions, I would maybe paywall statistics or sth or other advanced features but thats up to you ofcourse.

Hey thanks for bringing the sign up issue to my attention. The issue was that there was a name field at the top, but if not filled out it provided no feedback. I'm going to make it so you can just press Enter to skip the countdown as well. Thanks for giving it a try.
