SchildiChat Next

SchildiChat Next is a Matrix client based on the Element X app, with various tweaks and additional features.

The Matrix protocol is a decentralized approach to modern messaging, allowing you to select a server provider of your choice (or even self-host your own server), enabling you to communicate with end-to-end encryption, shared message history across multiple devices, and more.

SchildiChat is open source: https://github.com/SchildiChat/schildichat-android-next
