Hello. I'm an experienced mobile app developer with more than 7 years of experience in developing Android and iOS applications. I am confident that I can help you in creating the "Zap Sender" app for sharing messages, pictures, and videos with multiple contacts.
To clarify the requirements, I kindly request the following information:
1. What specific platforms do you intend to target, Android, iOS, or both?
2. Do you have any preferences for the user interface and design of the app?
3. Are there any additional features or functionalities you would like to include in the app, such as message scheduling or message encryption?
4. Would you like to explore options for storing user data securely and ensuring data privacy?
Let's have a quick chat session to discuss the project thoroughly. I look forward to connecting with you on the development of the "Zap Sender" app.
