Signal
signal.orgProbably one of the most popular, secure private messaging apps that combines strong encryption (see Signal Protocol) with a simple UI and plenty of features. It's widely used across the world, and easy-to-use, functioning similar to WhatsApp - with instant messaging, read-receipts, support for media attachments and allows for high-quality voice and video calls. It's cross-platform, open-source and totally free. Signal is recommended by Edward Snowden, and is a perfect solution for most users.

Signal - Private Messenger
Signal is a messaging app with privacy at its core. It is free and easy to use, with strong end-to-end encryption that keeps your communication completely private. • Send texts, voice messages, photos, videos, GIFs, and files for free. Signal uses your phone’s data connection, so you avoid SMS and MMS fees. • Call your friends with crystal-clear encrypted voice and video calls. Group calls supported for up to 50 people. • Stay connected with group chats up to 1,000 people. Control who can post and manage group members with admin permission settings. • Share image, text, and video Stories that disappear after 24 hours. Privacy settings keep you in charge of exactly who can see each Story. • Signal is built for your privacy. We know nothing about you or who you’re talking to. Our open source Signal Protocol means that we can’t read your messages or listen to your calls. Neither can anyone else. No back doors, no data collection, no compromises. • Signal is independent and not for profit; a different kind of tech from a different kind of organization.

More Encrypted Messaging
Matrix is a decentralized open network for secure communications, with E2E encryption with Olm and Megolm. Along with the Element client, it supports VOIP + video calling and IM + group chats. Note that homeservers can log IP addresses and metadata, and unrelayed 1:1 calls may reveal your IP to the other party.
Simplex is gaining popularity as a secure and private messaging app renowned for its robust encryption protocol without user IDs or phone numbers and this improves your privacy. Simplex offers instant messaging, supports media attachments and voice and video calls. Additionally, it is cross-platform, open-source, and completely free, aligning with the modern user's preferences for convenience, security, and accessibility. Learn more about the Security Policy.
XMPP, also known as Jabber, is an open standard for decentralized messaging that has been widely used for decades. It has actually been the basis upon which WhatsApp, Facebook's Chat and Google's Talk were built, but these companies (eventually) chose to remove the interoperability with other servers. Prominent XMPP clients support OMEMO end-to-end encryption, which is based on the Double Ratchet Algorithm that is used in Signal. For more hands-on information and to register an account you can visit JoinJabber.
