Free Brain Training Games That Actually Work
Most brain training apps are just games. Dual N-Back is different - it's backed by real science.
Why Dual N-Back is Different
While popular brain training apps like Lumosity and Peak have been criticized for lacking scientific evidence, Dual N-Back has been studied in peer-reviewed research since 2008.
The landmark Jaeggi study showed that just 20 minutes of daily Dual N-Back training can improve fluid intelligence - your ability to solve new problems.

What Does the Science Say?
Jaeggi et al. (2008) - The original study that started it all. Participants who trained with Dual N-Back showed significant improvements in fluid intelligence tests.
Au et al. (2015) - A meta-analysis of 20 studies confirmed that N-Back training produces small but significant improvements in fluid intelligence.
Johns Hopkins (2017) - Researchers found that Dual N-Back training was nearly twice as effective as other brain training methods.
