Nitro Messenger vs Katt messenger

Nitro is a private messenger built on a simple promise: the server cannot read your messages. Content is end-to-end encrypted with a post-quantum hybrid ratchet, so your conversations stay yours — even against tomorrow's computers. WHY NITRO • End-to-end encrypted messages, calls and media — keys live only on your device. • Post-quantum hybrid encryption, not just classic crypto. • The server is a "dumb carrier": it routes opaque, encrypted envelopes and never sees content. • No ads. No trackers. No third-party analytics. Your address book is never uploaded. • Your identity is a @username — your phone number is never shown to anyone. FEATURES • 1:1 chat with delivery receipts. • Photo sharing — images are encrypted on-device before they ever leave. • Voice & video calls with the native call experience (CallKit). • Group chats. • On-device, encrypted history — losing the server never loses your messages. • App lock with Face ID. PRIVACY YOU CAN VERIFY Every chat shows an encryption indicator, and you can confirm a contact face-to-face with a safety number. Delete your account anytime from Settings — your identity and history are wiped from the device. Nitro is single-device by design: no desktop or multi-device surface to attack.

MESSAGING - Private chats in real time: messages arrive instantly - Photos and videos straight from the camera or the gallery - Voice messages for when typing takes too long - Files and documents - Emoji reactions on any message - Replies, forwarding and deleting messages - Typing indicator and read receipts - See which contacts are online and when they were last active AUDIO AND VIDEO CALLS - High-quality calls directly between devices - An incoming call rings like a regular phone call, even when the app is closed - Switch cameras, mute the microphone and use the speaker during a call - Drag your own video to any corner of the screen MAKE SOMETHING FOR YOUR PEOPLE - Songs: describe the mood and Katt writes a song, even in your own voice - Photo editor: give a favorite photo a new look - Astrology: a personal conversation based on your birth chart Messaging and calls are free. Creating uses tokens: get them with a subscription (Basic, Plus, Pro) or buy a top-up pack. The subscription renews automatically until you cancel it in your App Store account settings. What you create in these sections is not protected by end-to-end encryption; this is explained in detail in the Privacy Policy. NOTHING EXTRA - Instant notifications that are easy to turn off - Mute or snooze notifications for any chat - Light and dark themes - A light app: it starts fast and is easy on the battery PRIVACY Katt does not ask for unnecessary permissions. There are no ads, and your conversations are not used to build a profile of you. All data travels over a secure connection, and messages are available only to you and the person you are talking to. Sign-up takes a few seconds. Find your contacts and start talking. Privacy Policy: https://katmessenger.com/#privacy Terms of Use: https://katmessenger.com/#terms
