I need a simple app for managing labour wages and vehicle rent payments. The calculations are already defined in an Excel file, and the app should replicate these functionalities. It must be compatible with Android devices and designed for my team members' use. Key features include: - Calculations for both labour wages and vehicle rent payment combined. - App must be compatible with mobile and Tab. - Data storage in Google Drive to allow access from multiple devices. - Ability to export detailed reports in Excel and PDF formats. The app's interface should be intuitive and help streamline these tasks while ensuring data is securely synced across devices through Google Drive. If you've developed similar apps or have expertise in integrating Google Drive, I'd love to hear from you! Low budget preferred.
