Keep using your favourite chat apps. Add Layergram protection before you share. Layergram encrypts messages on your device, letting you exchange protected content through the conversations you already use. Create your Layergram identities, verify each other and share encrypted messages without moving to a different messaging platform. THE LAYERGRAM KEYBOARD Fewer steps between your private message and your conversation. Enable the optional Layergram system keyboard, choose a verified contact and compose your message in its editor. The keyboard inserts the encrypted message into your chat. To read a reply, copy the incoming encrypted message and use Paste and decrypt. The readable text appears inside the Layergram editor. You choose whether to activate the keyboard and enable Face ID reopening when a session expires. Activation requires your consent and setup in both Layergram and iOS settings. PROTECTION ON YOUR DEVICE โข Hybrid post-quantum encryption with the Layergram v3 protocol. โข Local identities, shared through links or QR codes. โข Contact verification before exchanging protected messages. โข Forward-secrecy sessions with visible status indicators. โข Direct encrypted messages, links and cover messages. โข Local message history. Layergram does not operate a server that delivers your messages. Your chosen chat app transports the encrypted content. PREMIUM CONVENIENCE Core protection remains available for free. Premium adds tools for a more convenient workflow, including the in-app keyboard, multiple identities, folders and encrypted backup. On-device cover-message generation requires supported hardware. Feature availability and pricing are shown in the app and the store. YOU STAY IN CONTROL The recipient also needs Layergram and the correct identity. Your chosen transport service may still have access to contacts, timestamps and other metadata. Keep your recovery words somewhere safe. Restoring an identity does not automatically restore message history or conversation state.

the app to have that conversation. one line. two people. mono is an encrypted 1-to-1 messaging app. you can have only one conversation at a time โ no chat lists, groups, channels, or feeds. you connect via a unique, ephemeral 18-character key that rotates every 180 seconds. no matchmaking, stranger discovery, or public directory. no one can reach you unless you deliberately shared a key with them. no registration, no identity no name, email, phone, or personal data. no profile picture, no history, no trace โ nothing tied to your real identity. radical privacy every message is end-to-end encrypted โ only you and the other person can read it. not mono, not any server, not anyone else. ephemeral messages only the last 15 messages stay visible. the rest is permanently deleted. cut the line either person can cut the line โ everything is deleted for both, instantly and permanently. screenshot protection (iphone and mac) messages, keys, photos, videos, and files stay hidden from screenshots and screen recordings. optional protection face id, passcode, keyword lock, and an emergency panic pin. 36-hour rule after 36 hours of inactivity, the entire conversation is permanently deleted for both. no notifications no badges, no banners, no sounds. no extras just text, images, videos, and files. no calls, video calls, or voice notes. view once images, videos, and files open once per person, then lock for good.

Verdict
The clearest difference is in-app purchases: mono at none against Layergram's 1. Layergram's advantage is iOS requirement (15.5 vs 26.2). On price, update cadence, ads and device support there is nothing between them.
