I need a streamlined, in-house mobile application dedicated to employee management, focused solely on attendance tracking. Instead of the old paper log, every team member will check in and out by scanning a QR code posted at the office entrance. Each scan must instantly time-stamp the event and write it to a secure database that I can access through a simple web dashboard. The scope stops at attendance—no task assignment or performance evaluation features are required right now. What matters is that the scan process is fast, reliable, and works even if the device briefly loses its data connection, syncing automatically once online again. From the admin side, I want to be able to generate or refresh QR codes, view daily/hourly logs, filter by employee or date, and export those records to CSV. Acceptance criteria: • Mobile app (Android and iOS or a cross-platform alternative) scans QR codes and stores check-in/out times. • Offline capture with auto-sync once connectivity is restored. • Web dashboard lets me search, filter, and export attendance data. • Clean, intuitive UI that a first-time user understands without training. Feel free to propose the tech stack—Flutter, React Native, Kotlin/Swift, or another option—so long as scanning is instantaneous and the data layer remains secure and easy to maintain.
