StealthText

StealthText hides a short secret message inside a normal-looking one. You type a cover message, add the hidden part, and tap Seal & Copy. What lands on your clipboard reads the same as what you typed — but it carries the hidden text invisibly, encoded as zero-width Unicode characters.

Paste a message containing hidden content back into StealthText and the secret reveals itself, one character at a time.

Built for one hand

No tabs, no modes, no settings to learn. A single compose card auto-detects whether you’re encoding or decoding based on what’s in front of it. An Action Extension lets you decode straight from any iOS share sheet — Messages, Notes, Mail, Slack, anywhere you can share text — without leaving the app you’re in.

On-device, always

There are no accounts. No network requests. No analytics. No crash reporters. Your messages are stored locally using SwiftData and never leave your phone. If you delete the app, they’re gone.

Not encryption

StealthText hides messages. It does not encrypt them. Anyone with the right tool can extract the hidden text from a shared message — the secrecy is in nobody thinking to look, not in a key they couldn’t break. Use it for plausibly-invisible notes, not for anything a determined adversary would want to read.

Free, with an optional tip jar

StealthText is free. If it earns a place on your home screen, there are three one-time tips inside Settings. That’s the whole monetization model.
