Need An Android & IOS app

Hello I would need a simple app. The app will consist of a calender : **1. User Registration:** - Admin creates a new user by providing a username and password. - Store the user's credentials securely in a database, with password hashing and salting for security. **2. User Login:** - User enters their username and password on the login page. - The system checks the provided credentials against the database records. - If the credentials are valid, the user is granted access to their account. **3. User Home Page:** - Upon successful login, the user have access to calender and chat **4. Availability Calendar:** - On the user's home page, display a calendar where users can set their availability. - Users can click on specific dates and indicate their availability (e.g., available, unavailable). - Store the user's availability information in the database. **5. Chat Section with Admin:** - Include a chat section on the user's home page where they can send messages to the admin. - Admin should also have a corresponding chat interface to receive and respond to user messages. - Use a real-time communication system. **6. Admin's Response:** - The admin receives messages from users in real-time through the admin interface. - Admin can respond to user messages, offer assistance, and handle any scheduling or support requests. **7. Notifications:** - Implement notification mechanisms to alert both the admin and the user when a new message arrives in the chat. **8. Security:** - Ensure the security of the system with proper authentication, authorization, and encryption for user data and communication. **9. Database Management:** - Keep the user data and availability records in a secure and well-structured database. - Regularly back up and maintain the database. **10. User Management:** - Allow the admin to manage user accounts, including creating, updating, and deleting user accounts. Budget is low but as soon app is setup then i will know your expertise also and increase budget for more features added. (BUDGET IS SET ALREADY AND IF FAKE BID WILL BE BLOCKED & REPORTED) DON'T LOSE YOUR BID IF YOU DON'T WANT TO EARN A LONG TERM PROJECT WITH GOOD REVIEWS. This is a personal app and it would be use internal purposes and i would also need you to make the design also. Thank you
