Sigil

Comprehensive cryptography suite for Android with a modern Material 3 interface

Mobile appfree

Sigil is a free, open-source, zero-trust cryptography and privacy suite for Android offering multi-layer encryption behind a modern Material 3 interface. It's for Android users who want a single comprehensive toolkit for encrypting text, files, or other data on-device rather than piecing together several separate crypto apps. It's still early-stage (pre-v0.5.0) so not all planned features are complete.
