NoSave Chat

NoSave Chat is a small Android app for starting chats without saving a phone number first. Enter a number with country code, then open it in WhatsApp, Telegram, or Signal.

The app is built with Dioxus 0.7 and Tailwind CSS.

Features

• Open WhatsApp chats with wa.me links.
• Open Telegram phone links.
• Open Signal phone links.
• Mobile-first Dioxus layout.
• Catppuccin-inspired Tailwind theme.

Requirements

• Rust
• Dioxus CLI 0.7
• Android SDK, NDK, and emulator tooling
• Tailwind CSS CLI

Useful targets:

rustup target add aarch64-linux-android
rustup target add x86_64-linux-android

Development

Common commands:

make serve
make android-build
make tailwind-watch
make install-apk TARGET=aarch64-linux-android

Run Tailwind in one terminal:

make tailwind-watch

Run the Android app in another terminal:

make serve

The generated stylesheet is committed at assets/tailwind.css because automatic Tailwind generation through dx serve --android may not run consistently in this project.

Build

Build a release Android App Bundle for ARM64 phones:

make android-release-bundle TARGET=aarch64-linux-android

Build an APK for local install/testing:

make android-apk-bundle TARGET=aarch64-linux-android

For release APKs with automatic icon replacement:

make android-release-build TARGET=aarch64-linux-android

Release workflow rule:

• Version in Cargo.toml is used for local make release artifact naming.
• Git tag releases must use v<version> and must exactly match Cargo.toml.
• Example:

git tag -a v1.2.3
git push origin v1.2.3

This publishes NoSaveChat-v1.2.3-aarch64-linux-android-release.apk.

For x86_64 emulators, use:

make android-apk-bundle TARGET=x86_64-linux-android

Notes

This app is currently mobile-only. It does not use Dioxus fullstack features. A future local history feature can be implemented with local device storage and does not require a backend.
