# Mobile UI · Expo & React Native

Implementation guidance for Expo/React Native navigation, safe areas, native sheets, PWA boundaries and shared SONIC semantics.

This page owns **developer implementation rules** for the SONIC mobile product. Product behavior and screen hierarchy live under **Applications → Mobile Applications**.

## Native implementation

* Expo Router for application routing;
* safe-area aware layouts;
* native-feeling bottom sheets for advanced controls;
* minimum 44×44 touch targets;
* reduced-motion and accessibility labels;
* semantic theme tokens for System/Light/Dark;
* no desktop canvas scaling;
* secure authentication/session and wallet boundaries remain server/provider authoritative.

## Product shell

The current mobile product uses five primary destinations:

```
Home · Projects · Studio · Wallet · Settings
```

The centered Studio control belongs to that five-item navigation contract and is not an extra duplicate route.

PWA caching must exclude authentication, security, wallet, transaction, checkout, mint, private chat/audio job and other sensitive mutation/state endpoints.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://sonic-ai-works.gitbook.io/sonic-networks-docs/documentation/developers/frontend-and-design-system/mobile-ui-expo-and-react-native.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
