Michi is a next-generation notes app that helps you collect your everyday thoughts, learnings, and emotions—and reflect on what’s happening inside you. Most people don’t stick with note-taking for one simple reason: capturing and organizing takes too much effort. And even when you do write things down, they often disappear into a pile you never use again. Michi is built to solve that at the root. 1. Capture with zero friction Save the moment your mind moves—instantly—with text, voice, or images. You don’t need to “write neatly” or organize as you go. That’s not your job. Before a good idea evaporates, catch it. 2. Let AI handle the organizing AI automatically tags and links your notes, connecting related ideas for you. No folders to maintain, no rules to design—just focus on capturing what matters. 3. Watch “you” take shape See how your thoughts connect through a visual graph. Recurring themes, shifts from months ago, growing interests, and unexpected links start to emerge. Even a quick glance can reveal hints about who you are right now. 4. A map of you, built from your notes Michi isn’t just about storing notes—it’s about using them. Over time, your daily entries evolve into a “map of you” that supports reflection, better choices, and deeper self-understanding. Sync across devices & export Access the same notes anywhere with seamless cross-device sync. Export via GitHub anytime—so you can keep your data portable and connect it with other AI tools your way. Pricing Michi is available as a monthly subscription (details in the app). Terms of Use (Apple Standard EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Day Base is your database for everything — a simple, powerful place to organize, track, and keep the things that matter. Most apps decide what you can store. Day Base hands you the blueprint: create your own collections, define your own fields, and shape the app around your life instead of the other way around. WHATEVER YOU COLLECT OR TRACK Books, records, and wine. Sneakers and trading cards. Home inventory and warranties. Travel memories and restaurants. Recipes, plants, projects, clients — if you can list it, you can build it. DESIGN YOUR OWN FIELDS Add exactly the fields each collection needs — text, numbers, dates, yes/no, links, single-select, and photos. No rigid templates. Your data, your structure. SEE IT YOUR WAY Browse a beautiful card view with cover images, or switch to a sortable table to scan and compare. Tap any photo for a full-screen look. START IN SECONDS Already have a spreadsheet? Paste a CSV and Day Base builds the fields for you automatically — no setup required.
