Cross-Platform Wearable App Developer Needed (iOS/Android)

Project Overview
I’m seeking an experienced mobile developer to create a cross-platform application for both iOS and Android that will interface with a BLE wearable device. The app will process biometric data, feature a conversational AI interface, and update visual elements based on user interaction.

Technical Requirements

Core Functionality
• Cross-platform app development for iOS and Android app stores
• BLE (Bluetooth Low Energy) integration with a wearable device
• Processing and visualization of biometric data
• Conversational AI/chatbot interface implementation
• Dynamic color display system that updates based on chat interactions
• Device settings management interface
• Secure data storage and privacy controls

Technical Skills Required
• Proven experience with React Native or Flutter
• App Store and Google Play submission process familiarity
• BLE implementation for wearable devices
• Experience developing apps that visualize health/biometric data
• Chatbot or conversational interface implementation
• Real-time data visualization, particularly with color-based systems

Similar Apps for Reference
• Functionality similar to other Smart Ring’s biometric display and tracking
• Conversational elements similar to mental wellness apps like Woebot or Replika
• Visual color updates similar to mood tracking in apps like Daylio

Project Scope
• Complete app development from concept to store submission
• Ongoing maintenance and updates may be required

Deliverables
1. Functional cross-platform application for both iOS and Android
2. Backend integration for the chatbot functionality
3. BLE integration with the wearable device
4. Complete source code with documentation
5. Deployment to both app stores

Development Tools
• We expect candidates to be proficient with AI coding assistants like Cursor or WindSurf to enhance productivity and code quality
• Experience using these tools for efficient development is highly desirable

Additional Information
• Please share examples of previous mobile apps you’ve developed, especially those involving:
• Wearable technology integration
• Health or biometric data visualization
• Conversational interfaces or chatbots
• Dynamic visual elements that update based on user data
• Include your approach to cross-platform development and estimated timeline
• Indicate your availability to start and preferred working hours
