Cortx is a mobile learning app designed for professionals who want to use small pockets of time more intentionally. Instead of passive scrolling, users get 3-minute daily sessions with condensed book summaries and real-world strategy scenarios drawn from business and cognitive science. A Cognitive Depth Score tracks how well your thinking is developing over time, giving you a concrete measure of progress rather than just content consumption. The app has attracted over 2,400 active users, holds a 4.9-star rating, and is free to download on iOS and Android with a premium tier at ₹49/month.
