# PushGenius

> PushGenius is a push notification platform for iOS, Android, React Native, Flutter, Ionic / Capacitor, and web apps: target segments, schedule in each user's timezone, and track delivery and taps.

- The mobile SDKs share one API on the `BigBrain` class: `BigBrain.initialize("YOUR_APP_ID")`, `BigBrain.Notifications.requestPermission(true)`, `BigBrain.login(externalId)`, `BigBrain.User.addTag(...)`.
- Packages: Swift Package `https://github.com/PushGenius/ios-sdk.git`, JitPack `com.github.PushGenius:android-sdk`, npm `@pushgenius/react-native` and `@pushgenius/ionic`, pub.dev `pushgenius`. Server SDK for the REST API (Node.js, Bun, Deno, Cloudflare Workers): npm `@pushgenius/javascript`.
- The REST API is at `https://api.pushgeni.us`, authenticated with `Authorization: Key YOUR_REST_API_KEY`. Keep that key on the server.
- The app ID and REST API key are in the dashboard (https://app.pushgeni.us) under Settings.
