Hello fellow developers and app enthusiasts,
I hope you're all doing well. I run an event planning business and have a background in Java Full Stack with Angular. I've decided to take my business to the next level by developing an app to streamline the event planning process and offer more convenient solutions to my clients. However, I'm looking for some guidance on how to go about this exciting project.Here's what I have in mind and the advice I'm seeking:

1. Platform Choice: Since I have experience with Java Full Stack and Angular, I'm inclined to use these technologies for my app. Do you think these technologies are a good choice for app development, or should I consider something else?
2. Learning New Skills: I'm aware that app development may require additional skills beyond what I already know. What new skills or technologies do I need to learn in order to develop a successful event planning app? Any recommendations on online courses or resources for these?
3. App Development Process: I'm relatively new to app development, and I'm wondering about the overall development process. What are the key stages involved in creating an app, from concept to launch? Are there any best practices or frameworks that I should be aware of?
4. Monetization Strategies: I'm planning to make this app a part of my business model. Any insights on effective monetization strategies for event planning apps, like subscriptions, one-time payments, or in-app advertising?5. Building a Team: If my project grows, I might need to expand my development team. How do I find and collaborate with skilled developers, designers, and other professionals who can help bring my app to life?
5. Marketing and Promotion: Once the app is developed, marketing and promotion will be crucial. Any tips on how to effectively market an event planning app to potential users and clients?Your advice and insights on any of these topics would be greatly appreciated. I'm really excited to embark on this journey and I want to make sure I'm heading in the right direction. Thanks in advance for your help!
