Peak is the best-value pick among the established brain training apps — polished, varied, and well below Lumosity on price. Its personalization is good rather than category-leading, but as a daily all-rounder it is hard to fault.
Peak calls itself a “mobile gym for your brain,” and of the established brain training apps, it is the one that most impressed us on craft. We tested it for thirty days.
A genuine point in its favor
Most brain training apps make vague gestures toward neuroscience. Peak can point to something more specific: several of its games were developed with academic researchers. Its Decoder attention game came out of work licensed from the University of Cambridge.
This does not exempt Peak from the broader scientific caveats covered in our guide on whether brain training works — but the academic collaboration is real.
What works, what to know
- Excellent, modern design
- Strong variety — 45+ games, 6 categories
- Coach feature builds goal-based plans
- Well below Lumosity on price
- Personalization good but not category-leading
- No conversational coach
- Some "emotional training" games less proven
- Full statistics locked behind Pro
Peak’s Coach tunes difficulty and assembles workouts well, but it does not reshape your overall program the way Zenelia’s adaptive AI does, and there is no chat-based coach.
How it scores
On our five-criterion framework, Peak scores well on engagement, price-to-value, and breadth, with a modest bump on science for the genuine academic collaborations. The weighted result is 8.0 out of 10, placing it fourth in our roundup.
The bottom line
Peak is the established brain training app we would recommend to most people — polished, varied, well-priced, and pleasant to use daily. Choose it if you want a familiar name with a large catalog and cross-platform support without paying Lumosity’s premium. If deeply adaptive AI training is your priority, Zenelia does that better. Try the free tier, then step up to Pro for the full picture.
