Klio - Brain Training

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.

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.
