Cortex: Linked Study Notes

Cortex: Linked Study Notes is a learning notes app designed from the ground up for iPhone and iPad. Capture lecture takeaways, reading notes, and ideas in seconds, then reconnect them through links, search, and backlinks when it is time to review. **Why Cortex?** Unlike desktop-first note apps squeezed onto mobile, Cortex is built native — fast, beautiful, and designed for how you actually use your iPhone and iPad. **Built for Learning** Use Cortex for class notes, reading notes, revision prep, and the ideas you want to remember later. It is designed to help you keep what matters without turning note-taking into a project. **Connect What You Learn** Link notes together with simple [[wiki-links]]. Every connection is bidirectional — when a topic appears again, Cortex helps you find the related note without making you manage a complicated system. **Capture Instantly** Quick Capture lets you save a takeaway from a lecture, a reading, or an idea in seconds. Add it to Today or save it as a standalone study note. **Daily Notes** A fresh note is created for you each day. Use it to jot down what you learned today, what to review next, or what still feels unclear. **Powerful Search** Find anything across your entire knowledge base. Search by text, tags, or note type. Results show matching context so you can get back to the right note instantly. **Organized with Tags** Add #tags to any note. Browse your tags visually and filter notes by topic. Tags and links work together to make your knowledge easily navigable. **Designed for iPhone & iPad** On iPhone: tab-based navigation with a floating Quick Capture button. On iPad: a full sidebar, multi-column layout, keyboard shortcuts, and pointer support. Not one UI stretched — purpose-built for each device. **Dark Mode** A custom warm dark theme that's easy on your eyes during late-night thinking sessions. Not a simple white-to-black inversion — carefully designed colors throughout. **Focused for Daily Use** Core features are built around the workflows learners return to every day: capture, linking, backlinks, tags, daily notes, favorites, and search. **Your Data, Your Device** Notes are stored locally on your device. No third-party servers. No tracking. Your knowledge stays yours. ## Pricing Model Paid upfront on the App Store. The current release does not include in-app purchases, subscriptions, or restore-purchase flows.
