### ⚠️ Signal's One Big Problem

Signal is brilliant — but it requires your **phone number**. That is not a small detail. Your phone number is one of the most powerful identifiers that exists. It links to your name, your address, your bank, your government ID.

Signal encrypts your messages perfectly. But it still knows *your number talked to this number at this time.* That metadata pattern — even without reading a single message — is enough to map your entire social network. Governments and intelligence agencies have been using metadata analysis for decades.

Z-TEXT has no phone number. Your identity is a cryptographic z-address. Nobody knows who owns it.

### Honest Verdict

**Signal is the best choice for most people.** It is free, beautiful, fully featured, open source, regularly audited, and used by 40 million people including journalists, lawyers, and activists worldwide. If you want to replace WhatsApp — Signal is your answer.

**Z-TEXT is for the next level.** When Signal is not enough — when you cannot give a phone number, when you need to disappear completely, when metadata itself is the threat — Z-TEXT fills the gap Signal cannot fill.

They are not competitors. They solve different problems. Use Signal for everyday private communication. Use Z-TEXT when your identity itself must not exist.
