The Notesnook mobile app is developed with React Native, helping us to keep a shared codebase for iOS and Android apps and provide great feature parity on both platforms.
## Releases
Android and iOS apps can be downloaded from their respective appstores.
Alternatively on android releases are also available on [Github Releases](https://github.com/streetwriters/notesnook/releases).
## Architecture overview
The app codebase is distributed over two primary directories. `native/` and `app/`.
-`native/`: Includes `android/` and `ios/` folders and everything related to react native core functionality like bundling, development and packaging. Any react-native dependency that has native code i.e android & ios folders, is installed here.
-`app/`: Includes all the app code other than the native part. All JS only dependencies are installed here.
-`components/`: Each component serves a specific purpose in the app UI, for example the `Paragraph` component is used to render paragraphs in the app and a `Header` component is used to render a `header` on all screens.
-`common/`: Features that have integral role in app functionality, for example, notesnook core is initialized here.
-`hooks/`: Hooks for different app logic
-`navigation/`: Includes app navigation specific code. Here the app navigation, editor & side menu are rendered side by side in fluid tabs.
-`screens`: Navigator screens.
-`services`: Parts of code that do a specific function, for example, the `sync` service is responsibe for running Sync from anywhere in the app.
-`stores`: We use `zustand` for global state management in the app. There are multiple stores that provide the state for different parts of the app.
-`utils`: General purpose stuff such as constant values, utility functions etc.
There are several other folders at the root:
-`share/`: Code for the Share Extension and Android widget.
-`e2e/`: Detox End to end tests
-`patches/`: Patches for various react native dependencies.
