## What is Klio?

Klio is a focused training app for working memory, built around Dual N-Back, the task most studied for its link to working memory and fluid reasoning.

Each session is short and deliberate. You hold a growing sequence in mind, track what matches, and the difficulty adapts to keep you at the edge of your ability. No clutter, no noise, just the work.

What you get:
- Adaptive Dual N-Back that adjusts to your level
- Clear progress over time, session by session
- A daily reminder and a quiet streak to help the habit hold
- A calm interface designed to keep you present
- English and Spanish

Klio is local-first. Your training data stays on your device.

Klio Plus removes the one-session daily limit and opens deeper training. Start free and build the habit first.

Klio Plus is an auto-renewing subscription, offered monthly, six-month, and annual. Payment is charged to your Apple ID at confirmation of purchase. It renews automatically unless cancelled at least 24 hours before the period ends. A free trial converts to a paid subscription unless cancelled before it ends. Manage or cancel anytime in your App Store account settings.
