Basic calendar app for kids. Multi platform and must be visual and have customizable activity tiles.

I am looking for a skilled app developer to build a unique and fun calendar for kids. This app needs to be visually appealing, utilizing vibrant colors to engage and capture the interest of its young users. Key Requirements: - Being knowledgeable in multi-platform development is a must as the app needs to be compatible with iOS, Android, and Web platforms. - The app should incorporate customizable activity tiles to provide a personalized experience. - Activity tiles occupy the time they take up within the calendar. I.e a school activity that takes 30 minutes would block out 30 minutes in the app but an activity that takes 4 hours would occupy 4 hours in the calendar. - Ability to achieve a visually fun, vibrant color style to encourage interaction. Ideal skills and experience for the freelancers: - Experience in mobile and web application development. - Proficient in creating visually appealing and interactive mobile applications. - Proof of work on vibrant, color-rich applications will be preferred. I am particularly interested in understanding your experience for this project. Please don't hesitate to detail your relevant experience in app development. I am eager to hear how your skills and experience make you the best fit for this project.
