How It Works

Three steps. Ten minutes. Real progress.

Each session presents a passage matched to your level, asks targeted questions, and scores your response across six cognitive dimensions.

1

Read a passage

A short text from one of 22 domains — neuroscience, world history, philosophy, space exploration. Matched to your preferred topics and current difficulty level.

2

Answer & summarize

Recall key details, compress information, and reason coherently. Each exercise type targets a different cognitive skill. Long-press any difficult word for an instant definition.

3

Track your growth

Get your CPI score with strengths, weaknesses, and specific tips. Watch your trends over weeks and months. Share progress reports with your clinician.

Why Myndra

Not another brain game

Unlike general brain training apps, Myndra focuses on reading comprehension — the cognitive skill most impacted by brain injury and most predictive of daily functioning.

Your data never leaves your device

No analytics SDKs. No data sold. Ever. Your cognitive data stays on your iPhone. Export anytime to Obsidian or plain text.

Transparent, not a black box

Your CPI score is calculated from six measurable dimensions with a published formula. You see exactly what each score means and how to improve it.

Comprehension-first training

Every exercise is built around reading comprehension — recall, summarization, and coherent reasoning. Targeted rehabilitation, not a puzzle game.

28 citations, not marketing claims

Every exercise methodology is backed by peer-reviewed research. Browse the full citation library inside the app — no other brain training app does this.

The Science

Six dimensions, one score

Your Cognitive Performance Index (CPI) measures the skills that matter most for comprehension and daily cognitive function.

Recall

Accuracy of memory retrieval

Compression

Distilling information to essentials

Coherence

Logical structure of responses

Response Time

Processing speed under pressure

Listening

Attention to subtle details

Working Memory

Holding multiple ideas at once

Features

Built for real cognitive training

Structured exercises with adaptive difficulty, longitudinal tracking, and evidence-based methodology.

Adaptive difficulty

Ten levels that respond to your recent session performance. The app levels up when you're consistent and backs off when you're struggling — no manual adjustment needed.

Longitudinal trends

Visualize cognitive performance over weeks and months. See how each dimension evolves and get improvement tips tailored to your specific scores.

22 knowledge domains

Choose preferred topics from neuroscience to philosophy, space exploration to world history. Learn while you train your comprehension.

Obsidian export

Export your cognitive training data as Obsidian-compatible markdown with YAML frontmatter. Integrate brain health into your personal knowledge system.

Who It's For

For people who take cognitive health seriously

Brain injury recovery

Structured daily exercises that adapt to your current capacity. Track longitudinal progress to share with your care team. Comprehension training is the foundation of cognitive rehabilitation.

Cognitive maintenance

Stay mentally sharp as you age. Daily comprehension exercises that challenge different cognitive skills and build consistency over time. Ten minutes a day.

Students & learners

Improve reading comprehension, retention, and the ability to distill complex information. 22 knowledge domains mean you're always learning something new.

FAQ

Common questions

No. Myndra is a cognitive training tool, not a medical device. It is not intended to diagnose, treat, cure, or prevent any disease or condition. Always consult your healthcare provider about your cognitive rehabilitation plan.

On your device. Myndra uses local storage on your iPhone. No analytics SDKs, no ad networks, no tracking. You can export or delete all your data at any time.

Myndra focuses exclusively on reading comprehension — the cognitive skill most impacted by brain injury. It includes 28 in-app citations to peer-reviewed research, an Obsidian export feature, and a dedicated clinician tier with patient management. No other brain training app offers this combination.

CPI stands for Cognitive Performance Index. It is a composite score calculated from six dimensions: recall, compression, coherence, response time, listening, and working memory span. The formula is published and transparent — no black box.

Yes. The free tier includes one session per day with all exercise types, adaptive difficulty, basic scoring, and streak tracking. There is no time limit on the free tier.

Myndra's adaptive difficulty system draws from the ACTIVE trial (Ball et al., 2002), which demonstrated that cognitive training can improve targeted abilities for up to 10 years. The exercise methodology references 28 peer-reviewed papers across cognitive rehabilitation, neuroplasticity, and comprehension training. All citations are accessible inside the app.

Your brain adapts. Your training should too.
