Heavily inspired by Whatsapp and Signal, powered by Matrix. --- Project mantra - Tiny app size - currently 1.72mb~ when provided via app bundle. - Focused on reliability and stability. - Bare-bones feature set. ##### _*Google play only with automatic crash reporting enabled_ --- #### Feature list - Login with username/password (home servers must serve `${domain}.well-known/matrix/client`) - Combined Room and DM interface - End to end encryption - Message bubbles, supporting text, replies and edits - Push notifications (DMs always notify, Rooms notify once) - Importing of E2E room keys from Element clients #### Planned - Device verification (technically supported but has no UI) - Invitations (technically supported but has no UI) - Room history - Message media - Cross signing - Google drive backups - Markdown subset (bold, italic, blocks) - Changing user name/avatar - Room settings and information - Exporting E2E room keys - Local search - Registration --- #### Technical details - Built on Jetpack compose and kotlin multiplatform libraries ktor and sqldelight (although the project is not currently setup to be multiplatform until needed). - Greenfield matrix SDK implementation, focus on separation, testability and parallelisation. - Heavily optimised build script, clean _cacheless_ builds are sub 10 seconds with a warmed up gradle daemon. - Avoids code generation where possible in favour of build speed, this mainly means manual DI. - A pure kotlin test harness to allow for critical flow assertions [Smoke Tests](https://github.com/ouchadam/small-talk/blob/main/test-harness/src/test/kotlin/SmokeTest.kt), currently Linux x86-64 only.
