Best Free Brain Training Apps in 2026
Updated: Aug 18
Last verified: August 2026 by Plasticity Brain Centers
Here at Plasticity Brain Centers, we spend every day working with patients recovering from concussion, stroke, and other neurological conditions — so we know firsthand how much consistency matters for brain health. Between in-clinic sessions, the right app can help you keep training at home.
We re-tested this list from the ground up this year. A few of our old favorites have been dropped (one app we used to recommend, Eidetic, is no longer available on the App Store), and we've added several apps that have built real clinical credibility since our last update.
How we evaluated these apps
We looked at four things for each app:
Evidence base — is there published or peer-reviewed research behind the exercises, or is it dressed-up casual gaming?
Free tier depth — how much can you actually do without paying?
Cognitive breadth — does it train one skill (like memory) or several (attention, processing speed, flexibility, language)?
Current availability — is the app still actively maintained in 2026?
Quick comparison
App | Best for | Free tier | Paid tier (from) |
Elevate | Everyday work skills (writing, math, reading) | Personalized daily program, limited games | ~$8–13/month |
Lumosity | Broadest game library (60+ games) | Baseline test + 1 daily workout | ~$12/month |
BrainHQ | Strongest clinical research base | "Daily Spark" exercise | ~$14/month or $96/year |
Peak | Budget-friendly, polished design | Full game library, capped sessions | ~$5–8/month |
CogniFit | Clinical-grade cognitive assessment | Initial assessment + limited games | ~$20/month |
NeuroNation | Targeted memory & concentration training | Assessment + core exercises | ~$12/month |
Cognitio | Story-driven, gamified training (iOS only) | Full story mode, limited stat tracking | One-time or subscription upgrade |
Free on iOS and Android. Elevate builds a personalized daily training program around quick, game-like exercises focused on productivity skills — writing, comprehension, math, and processing speed. Sessions are short (a few minutes each), which makes it an easy habit to build during a work break. The free tier gives you a real daily workout, not just a demo; the paid version unlocks the full game library and deeper progress analytics.
Free on iOS, Android, and web. Lumosity remains one of the most recognized names in brain training, built with input from neuroscientists and game designers together. It offers 60+ games across three categories — cognition, math, and language — and starts every user with a baseline test so you can track improvement over time. The free plan includes one training game per day; unlocking the full library requires a subscription.
BrainHQ
Free trial exercise daily, on iOS, Android, and web. Developed by Posit Science under neuroscientist Michael Merzenich, BrainHQ has the deepest published research base of any app on this list, with exercises built specifically to improve processing speed. It's a strong pick if you want an app backed by real clinical studies rather than repurposed casual games — particularly popular with older adults and anyone focused on measurable, research-supported gains.
Free on iOS and Android. Peak covers memory, language, mental agility, and attention across 30+ mini-games, with one of the more visually polished interfaces in the category. It shows your cognitive strengths relative to one another and lets you compare progress with friends. The free baseline version is genuinely usable on its own; the subscription adds a personalized training plan.
CogniFit
Free on iOS and Android. CogniFit leans clinical: it starts with a full cognitive assessment and is used by some healthcare providers alongside patient care (though it does not provide medical diagnosis or treatment). The free tier includes the initial assessment plus limited games; the Basic and Premium tiers unlock 20–60+ games and fuller tracking.
NeuroNation
Free on iOS, Android, and web. Developed in partnership with the Free University of Berlin, NeuroNation builds an adaptive training plan around your specific weak points after an initial assessment, with a strong focus on memory and concentration. It's less well-known in the US but has solid academic backing and a loyal following in Europe.
Free on iOS (iOS only). If the other apps on this list feel too clinical, Cognitio wraps brain training in a story — think secret agents and spy missions — while still testing memory, logic, and word skills underneath. It integrates with Apple Health, so you can see how sleep and activity are correlating with your training performance.
At Plasticity Brain Centers, we always tell clients that an app is a supplement, not a substitute — how you sleep, eat, manage stress, and move your body all shape brain health as much as any 15-minute daily game does. That's also why none of these apps replace the kind of structured, one-on-one neurological rehabilitation we provide in-clinic.
