Automation where several people can click on a iphone button which raises a counter which should be displayed as a iphone widget by one number

Project Description:
I am looking for a skilled developer to create an automation system for me. The main goal of this project is to develop a feature where several people can click on an iPhone button on their own device, which will then raise a counter.

It can be very simple.

Platform:
- The automation system should be developed specifically for iOS.

Preferred Programming Language:
- There is no specific preference for the programming language. The developer can choose either Swift or Java based on their expertise.

Level of User Interaction:
- A moderate level of user interaction is required for this project.

Ideal Skills and Experience:
- Proficiency in iOS development.
- Strong knowledge of Swift or Java programming languages.
- Experience in developing iPhone widgets.
- Understanding of user interaction and interface design.
- Ability to create a seamless and user-friendly automation system.
- Attention to detail in order to accurately track and display the counter on the iPhone widget.
