Read full descriptionHide full description
Look back at your past: how many of your decisions were truly the result of systematic thinking? Is your current life path one you genuinely chose for yourself? Without a systematic personal framework, path dependence becomes the greatest obstacle to personal growth. Fortunately, we can change this. By recording every new insight or piece of knowledge you gain, connections and profound understanding will emerge over time.

Key Features: 3D Mind Map View: Visualize your thoughts in a new dimension. Dual-Screen Support: Operate mind maps across two screens for maximum efficiency. Integrated Productivity: Built-in Calendar and Task Management system. Outline Mode: Instantly switch between visual maps and structured outlines. High Performance: Seamlessly handle thousands of nodes without lag. Unified Node Management: Manage nodes centrally across different maps. Actionable Links: Create direct links between mind map nodes and tasks. And much more...

Prep the Day is a morning ritual for getting your day in order. Every morning, open the app and type out everything you need to do today β fast, messy, stream of consciousness. Don't think about order or priority. Just get it out of your head. Then the on-device AI takes over. It reads your dump, pulls out the real tasks, drops the routine "noise," and hands back a clean, prioritized list for the day. One brain dump in, one focused task list out β every morning. ON-DEVICE & PRIVATE β’ All AI runs on your device using Apple Intelligence. Your text never leaves your iPhone or iPad. β’ No account, no sign-in, no servers, no tracking. β’ Works without an internet connection. WHY IT WORKS β’ A cluttered head makes for a scattered day. Writing it down clears it. β’ The AI does the sorting so you don't have to organize before you've even started. β’ Five minutes in the morning saves hours of "what was I supposed to do today?" FEATURES β’ Brain dump input β type everything on your mind β’ On-device AI task extraction, powered by Apple Intelligence β’ Noise filtering β trivial, routine items are dropped β’ Priority sorting β the list comes back ordered β’ Edit freely β add, rename, complete, and delete tasks β’ Session history β every morning's prep is saved on-device β’ English and Japanese Requires a device that supports Apple Intelligence, with Apple Intelligence turned on.
