How to Send Secret Messages Using Just the iPhone Notes App

If you're tired of messaging apps that leave behind a paper trail or want to plan a surprise without raising suspicion, your iPhone Notes app might be your new best friend. With a few taps, you can turn any note into a real-time, private chat by sharing it with a friend. Add them as a collaborator, and suddenly you’ve got a live document where both of you can type—and see—messages instantly, without sending a single text. Here’s how it works: start a new note, hit the share icon, invite your friend (make sure permissions allow editing), and send the link via text or email.

Once they join, you're free to chat, drop files, or even delete messages when you're done, making it feel like Snapchat but sneakier. You can also toggle on color-coded highlights to track who's saying what. To end the conversation, just remove the person or stop sharing the note entirely. No trace, no problem. It’s the kind of digital hideaway that feels almost too clever—but it’s built right into your iPhone.
