Replicate Android App for iOS + Watch

iWe are looking for a developer with strong experience in iOS, Swift/SwiftUI, and watchOS to build the Apple versions of an application that is already fully implemented and working on:

Android
Wear OS
Backend/API

This is not a project to be developed from scratch.

The developer will receive:

Complete Android application source code
Complete Wear OS application source code
Existing and functional backend and APIs
Authentication structure
Existing endpoints
Functional logic
User flows and navigation
Design and assets
Business rules
API request/response examples

The main goal is to reproduce the existing functionality within the Apple ecosystem.

iPhone Application

Development of the iPhone application using Swift/SwiftUI, keeping the functionality and overall user experience equivalent to the existing Android version.

Main areas include:

Login/authentication through API
Secure token management
Web/API integration
Mood check-in
Mood pattern display
Communication with the HUGiiNE backend
Notifications
Voice/microphone functionality and audio playback where applicable
Synchronization of activity/data supported by the Apple ecosystem
Session and logout management
Error handling and offline/network failure scenarios
Apple Watch Application

Development of the watchOS application, equivalent to the existing Wear OS version.

Includes:

Quick Mood registration
Mood pattern display
Secure communication with the backend
iPhone and Apple Watch synchronization where required
Session management
Appropriate behavior with limited connectivity
User interface adapted to Apple Watch

Technical Requirements

Proven experience with:

Swift
SwiftUI
iOS
watchOS
Xcode
REST APIs / JSON
Keychain
Apple Push Notifications
WatchConnectivity
Background tasks / synchronization
App Store Connect / TestFlight

Experience with HealthKit will be considered an advantage if required to reproduce activity-related functionality already available on Android.

Deliverables

The project must be delivered complete and fully buildable:

Complete iOS Xcode project
Complete watchOS target/project
Full source code
Assets
Configuration files
Documented dependencies
Error-free build
Testing of the main functionality
Version ready for TestFlight
Support for the first App Store submission
Fixes for any implementation-related issues identified during Apple App Review
Important

The existing Android and Wear OS applications will be provided as complete functional references.

We are not looking to redesign the product or change the existing backend architecture.

The objective is to obtain a stable, secure, equivalent Apple version, ready for publication.

Please include in your proposal:

Specific watchOS experience
Previous iOS/watchOS applications developed
Estimated delivery time
Fixed total project price
Whether App Store submission support is included
