Minimalist Labor Attendance Android App

I'm looking to develop a minimalist Android app designed for managing labor attendance across various sites. The app should be straightforward and efficient, allowing me to easily track and manage labor details without unnecessary complexity. A reference for the desired functionality is the ONSITE CONSTRUCTION app available on the Play Store.

Key Requirements:
- Ability to mark labor attendance at different sites
- Functionality to calculate daily wages for each laborer
- Generate reports on total labor costs per site
- No user authentication is required, ensuring ease of access and use

Ideal Skills and Experience:
- Experience in Android app development
- Proficiency in designing user-friendly, minimalist interfaces
- Strong understanding of data management and reporting within mobile applications
- Familiarity with apps similar to ONSITE CONSTRUCTION for reference and inspiration

I'm eager to collaborate with a developer who can bring this vision to life with simplicity and efficiency.
