Your relationships deserve more than a forgotten conversation. Ntd.Ink is a minimal, fast personal CRM built around one idea: keep notes on the people in your life. Capture every interaction Type the thought first and say who it was about second. Two taps from the home screen, or dictate it hands free. Voice notes, quick edits, pinned notes - everything stays in one clean thread per person. Say something, not nothing Knowing you should reach out is the easy part. Tap Wave and Ntd drafts the opening line from your own notes, then hands it to Messages, WhatsApp, Telegram or Mail with the words already in place. Nothing sends by itself. On an iPhone 15 Pro or newer with Apple Intelligence, your iPhone writes the suggestion and it never leaves the device. Add a picture to the moment Attach a photo to any note - the whiteboard from the meeting, the label of the wine they loved, a snapshot of the day. Tap to view it full screen. Reminders that follow the note Set a reminder directly on a note, not just on a contact. Each note carries its own follow-up, so you can track several with the same person without losing any. Make it repeat daily, weekly, or monthly - it keeps nudging you until you mark it done. Done, Later and Wave sit on the notification itself. Share your card without a server Your details become a QR code that holds the data itself. No account, no link, nothing to click. Anyone can scan it with their camera and get an ordinary contact card, and you choose exactly which details go in. Scan theirs just as easily. Stay organised Tag contacts, filter by tag, sort by recent activity or upcoming reminders. Find anyone in seconds with inline search. Built for focus No feeds, no social graph, no noise. Just you, your notes, and the people worth remembering. Widgets for capture, dictation, reminders and your card, plus five accent themes and alternate app icons to make it yours. Private by default Your data lives on your device. No account, no sign in, no servers. Nothing is shared.
