Hide secret messages inside ordinary-looking text using zero-width Unicode characters. The hidden message is invisible to the naked eye but extracts back instantly when pasted into Stealth Text. ONE SURFACE, ZERO MODES Type a message. Tap to add a hidden message. Seal & Copy — done. Paste a message containing hidden content and the secret reveals itself character-by-character. WORKS ANYWHERE The Action Extension decodes hidden messages straight from any iOS share sheet — Messages, Notes, Mail, Slack, anywhere you can share text. YOUR HISTORY, ORGANIZED Every message you encode or decode is saved locally with date-grouped sections, search, and filter chips for encoded, decoded, and favorites. Swipe right to favorite, left to delete. TRULY OFFLINE No accounts. No network requests. No analytics. No tracking. Your messages never leave your device. NOT ENCRYPTION Stealth Text hides messages — it does not encrypt them. Anyone aware of zero-width steganography can decode the hidden text. Use it to share secrets in plain sight, not to protect security-critical information. OPTIONAL TIP JAR Free forever. If you love it, leave a tip — Restore Purchases supported.
