Rootkeep is a personal CRM for your real life - the friends, family, mentors, and colleagues you actually care about. It tells you who needs you right now, helps you keep the promises you make, and remembers the details so you can show up like the thoughtful person you want to be. Inspired by the relationship philosophy of "Never Eat Alone", Rootkeep is built on one idea: strong relationships grow from small, consistent touches - not grand gestures. WHO NEEDS YOU RIGHT NOW Open the app and see exactly who to reach out to today. Rootkeep ranks the people you've gone quiet with, surfaces birthdays before you miss them, and turns your good intentions into one short, doable list. KEEP EVERY PROMISE Said "let's grab coffee soon" or "I'll send you that article"? Log it as a promise and Rootkeep holds you to it - front and center until you follow through. Checking one off feels as good as it should. LOG A CATCH-UP IN SECONDS A call, a coffee, a chance meeting - capture it in a few taps before you forget. Add who it was with, what you talked about, and what you promised. Follow-ups become reminders automatically. REMEMBER THE LITTLE THINGS Kids' names, favorite wine, the job change, the move to Lisbon. Keep notes on every person so your next conversation picks up right where the last one ended. NEVER MISS A BIRTHDAY Birthdays surface right in your daily list, exactly when it's time to reach out - no separate calendar to check. SET RELATIONSHIP GOALS Want to reconnect with old colleagues or invest in a mentorship? Link people to goals and let your daily nudges keep you moving. AI THAT HELPS, NEVER BLOCKS An optional AI advisor helps you think through your relationships - who to prioritize, how to reconnect after a long silence, what to say. Every feature works fully without it. PRIVATE BY DESIGN - No account. No sign-up. No tracking. - Your data lives on your device and syncs through your own private iCloud - never on our servers, because we don't have any. - Works completely offline. FREE, NO CATCH No subscription, no paywall, no ads. Your network isn't a spreadsheet. It's the people who will show up for you - if you show up for them. Rootkeep helps you show up.

Define your own types and relations too · Type "book" pops a search that fills the rest; "project" adds start/due to the calendar · Highlight a PDF and quotes collect into a note of the same name, searchable and on the graph · Wiki links, types, relations and PARA form one constellation — more links, brighter star ■ Infinite mindmap canvas (.canvas) · Apple Pencil drawing — turn a sketch into an AI image.
