This project aims to develop a smart ring integrated with a React Native mobile application. The smart ring will feature an e-ink display to show user habits, while the mobile application will allow users to manage and track these habits.

1. Project Roadmap
2. General Considerations
3. React Native App Development
4. Smart Ring Prototyping

• Conceptualization & Planning: Define the core features and objectives of the smart ring and mobile application.
• Component Acquisition: Purchase necessary components for the smart ring prototype.
• Breadboarding & Initial Testing: Set up components on a breadboard for initial testing.
• Firmware Development: Develop firmware for the smart ring's microcontroller.
• React Native App Development: Build the mobile application using React Native with Bluetooth integration.
• Integration: Ensure seamless communication between the smart ring and the mobile application.
• PCB Design & Assembly: Design a custom PCB for the smart ring and solder components.
• Testing & Iteration: Test the complete system and make necessary refinements.
• Miniaturization: Reduce the size of the smart ring prototype to fit a ring form factor.
• Final Deployment: Launch the product for users.

• Size & Comfort: The smart ring's size and comfort are paramount. Ensure components are miniaturized without compromising functionality.
• Battery Life: Optimize power consumption to maximize battery life, given the small form factor.
• Durability: The ring should be robust, waterproof, and able to withstand daily wear and tear.
• User Experience: Ensure the mobile application is user-friendly, intuitive, and provides value to the user.
• Feedback Loop: Regularly gather feedback from potential users and iterate based on their input.
• Collaboration: Consider collaborating with experts in areas where you might lack experience, such as electronics or native app development.
