-This is a new [**React Native**](https://reactnative.dev) project, bootstrapped using [`@react-native-community/cli`](https://github.com/react-native-community/cli).
+# CircleCollect
-# Getting Started
+CircleCollect is a React Native mobile app for organizing and managing group fund collections (rotating savings / contribution circles). Organizers create contribution groups, members join and contribute on a cycle, and a winner can be randomly selected each cycle. Payments are handled through an in-app payment gateway, and push notifications keep members up to date.
-> **Note**: Make sure you have completed the [Set Up Your Environment](https://reactnative.dev/docs/set-up-your-environment) guide before proceeding.
+## Features
-## Step 1: Start Metro
+- **OTP-based authentication** — login with a mobile number and one-time password; tokens stored securely with `react-native-keychain`
+- **Organizer registration** — regular users can apply to become organizers and register bank / mobile money details
+- **Group management** — create, edit, and review groups; browse public groups; approve or decline join requests; invite members from contacts
+- **Contributions and payments** — contribute to one group or pay several at once (bulk pay), choose a payment mode, and complete checkout in a payment gateway WebView
+- **Cycle winner selection** — randomly select a winning member for a group's current cycle
+- **Transactions** — view personal transaction history and group payment records
+- **Push notifications** — Firebase Cloud Messaging with Notifee for display, including deep-link redirection from a notification to the relevant screen
+- **Profile** — edit profile details, profile picture, and bank details
-First, you will need to run **Metro**, the JavaScript build tool for React Native.
+## Tech stack
-To start the Metro dev server, run the following command from the root of your React Native project:
+| Area | Library |
+| --- | --- |
+| Framework | React Native 0.81, React 19, TypeScript |
+| Navigation | React Navigation (native stack + bottom tabs) with deep linking |
+| State | Redux Toolkit + redux-persist (user, notifications) |
+| Server state | TanStack React Query with custom CRUD hooks (`useFetch`, `useCreate`, `useUpdate`, `useDelete`) |
+| Networking | Axios client with auth interceptors (`src/api/client.ts`) |
+| Push notifications | `@react-native-firebase/messaging` + `@notifee/react-native` |
+| Secure storage | `react-native-keychain`, AsyncStorage |
+| UI | React Native Paper, RN Elements, vector icons, Reanimated, linear gradient, calendars |
+| Payments | Gateway checkout via `react-native-webview` |
-```sh
-# Using npm
-npm start
+## Project structure
-# OR using Yarn
-yarn start

```
-## Step 2: Build and run your app
+The backend base URL and all endpoints are defined in `src/utils/ApiUrls.tsx`.
-With Metro running, open a new terminal window/pane from the root of your React Native project, and use one of the following commands to build and run your Android or iOS app:
+## Getting started
-### Android
+### Prerequisites
+
+- Node.js >= 20
+- A working [React Native environment](https://reactnative.dev/docs/set-up-your-environment) (Android Studio / Xcode)
+- Firebase configuration files in place (`android/app/google-services.json`, iOS `GoogleService-Info.plist`) for push notifications
+
+### Install dependencies
```sh
-# Using npm
-npm run android
-
-# OR using Yarn
-yarn android
+npm install
```
-### iOS
-
-For iOS, remember to install CocoaPods dependencies (this only needs to be run on first clone or after updating native deps).
-
-The first time you create a new project, run the Ruby bundler to install CocoaPods itself:
+For iOS, also install CocoaPods dependencies (first clone and after updating native deps):
```sh
bundle install
-```
-
-Then, and every time you update your native dependencies, run:
-
-```sh
bundle exec pod install
```
-For more information, please visit [CocoaPods Getting Started guide](https://guides.cocoapods.org/using/getting-started.html).
+### Run the app
+
+Start Metro:
```sh
-# Using npm
-npm run ios
-
-# OR using Yarn
-yarn ios
+npm start
```
-If everything is set up correctly, you should see your new app running in the Android Emulator, iOS Simulator, or your connected device.
+Then in a separate terminal:
-This is one way to run your app — you can also build it directly from Android Studio or Xcode.
+```sh
+# Android
+npm run android
-## Step 3: Modify your app
+# iOS
+npm run ios
+```
-Now that you have successfully run the app, let's make changes!
+## Scripts
-Open `App.tsx` in your text editor of choice and make some changes. When you save, your app will automatically update and reflect these changes — this is powered by [Fast Refresh](https://reactnative.dev/docs/fast-refresh).
+| Command | Description |
+| --- | --- |
+| `npm start` | Start the Metro dev server |
+| `npm run android` | Build and run on Android |
+| `npm run ios` | Build and run on iOS |
+| `npm test` | Run Jest tests |
+| `npm run lint` | Run ESLint |
-When you want to forcefully reload, for example to reset the state of your app, you can perform a full reload:
+## Configuration
-- **Android**: Press the R key twice or select **"Reload"** from the **Dev Menu**, accessed via Ctrl + M (Windows/Linux) or Cmd ⌘ + M (macOS).
-- **iOS**: Press R in iOS Simulator.
+- **API base URL** — set in `src/utils/ApiUrls.tsx` (`BASE_URL`). A commented-out local URL is provided for development against a local backend.
+- **Deep linking** — the app registers the `myapp://` scheme for notification redirection (see `src/navigation/AppNavigator.tsx`).
-## Congratulations! :tada:
