    Consistency:
                           Ensure design consistency with uniform fonts, colors and icons across the app.

                        Accessibility:
                            Incorporate accessibility features like larger text sizes, high contrast colors and
                           screen reader support.
                        Wireframes:

                           Sketch wireframes for each screen to visualize the layout and user flow.

                      3. Coding the App
                        Data Management:

                            Decide if the app will store data locally (using TinyDB) or in the cloud (using Firebase
                           or Google Sheets).
                        API Integration:

                            Integrate  third-party  APIs to  access  external data  (e.g., weather, maps,  etc.)  if
                           required.
                        MIT App Inventor Blocks:

                           Use the blocks editor effectively to build logical functions and interactive features.
                           Organize code blocks for easy readability and scalability.
                        Error Handling:

                           Implement checks to prevent crashes and provide user-friendly error messages.

                      4. Testing and Debugging
                        Test Regularly:

                            Conduct  unit  tests on  individual  features  and  full app  tests  at  each  development
                           stage.
                        Bug Tracking:

                           Maintain logs to track and resolve bugs during development.
                           Use platforms like GitHub or Google Drive for version control and backup.

                        Device Testing:
                            Test the app across different devices (phones, tablets) and screen sizes to ensure
                           compatibility.
                        User Feedback:

                           Collect feedback from target users to refine app usability and performance.

                      Key Takeaways:
                         Develop problem-solving skills through app development.

                         Gain hands-on experience with sensor integration and algorithm design.
                         Understand the importance of user-centered design in software development.
