## What it is
ChatSecure is a free and open source encrypted chat client for iOS that supports OTR and OMEMO end-to-end encryption over XMPP, with optional Tor connectivity. It interoperates with other XMPP clients like Conversations and Dino and encrypts local conversation logs with SQLCipher.

## Use cases
- encrypted chat on iphone
- private messaging app for ios
- xmpp client with omemo encryption
- chat over tor to bypass firewalls
- interoperable encrypted messaging with android users
- self-hosted secure chat client
- off-the-record messaging on ios

## When to choose
- you need an open source, auditable encrypted messenger on iOS
- you want XMPP federation and interoperability with Conversations or Dino
- you need OMEMO or OTR end-to-end encryption with forward secrecy
- you want to route chat traffic through Tor for censorship circumvention

## When to avoid
- you need a polished consumer messenger with modern features like video calls
- you want an Android client - ChatSecure Android is discontinued
- you need a license permitting closed-source App Store redistribution without an exception
- you prefer a simpler non-federated encrypted chat like Signal
