Smart Attendance Tracker Android App

In most colleges, attendance still runs on paper registers: faculty call out roll numbers, mark a register, and later transcribe the data to compute percentages and defaulter lists. The process eats five to ten minutes of every lecture, registers get lost, and defaulter lists arrive so late in the semester that students cannot course-correct. Biometric and RFID systems solve this with hardware that most departments cannot afford to install and maintain. This project takes the zero-hardware route instead: the faculty member's phone becomes the register. Classes, subjects, timetables and student rosters are managed in the app; the marking screen loads the roster with one-tap present/absent toggles and bulk actions; percentages recompute on every submit; and the reports module produces monthly summaries, defaulter lists and CSV exports. The design is offline-first because classrooms frequently have poor connectivity.

1. The faculty member sets up classes, subjects, the weekly timetable and student rosters once at the start of the semester.
2. On the day, the timetable view lists today's sessions; tapping a session loads its student roster into the marking screen.
3. Each row gets a present/absent toggle; bulk actions mark everyone present so only the absentees need flipping.
4. On submit, the session is stored with a timestamp and per-student running percentages are recomputed automatically.
5. The reports module aggregates the month: daily percentages, a bar-chart view and the defaulter list below the 75% threshold.
6. Monthly or date-range reports export as CSV for department records; the sync queue replays changes to the server when online.

Tech stack:

• Android (Kotlin or Java) with Android SDK
• SQLite via Room for local storage
• Material Design components for marking and reporting UI
• Background WorkManager for the sync queue
• CSV export via standard file APIs
• Optional REST endpoint for department-server sync

• [Class, subject and roster management] Create classes, subjects and time slots, and import or enter student rosters with roll numbers; the timetable view shows today's sessions ready to mark.
• [One-minute marking screen] Every student row carries a present/absent toggle, with mark-all-present plus exception flips so a full 68-student class is marked in under a minute (design target on typical devices).
• [Automatic percentage computation] Per-student running attendance percentages recompute from the attendance table on every session submit — no manual spreadsheet work.
• [Defaulter flagging] Students below the configurable threshold (default 75%, matching common university rules) are listed for monthly review with their absence counts.
• [Monthly and date-range reports] Daily, weekly and monthly attendance views with a bar-chart summary and one-tap CSV export for department records.
• [Offline-first with sync queue] All writes hit the local SQLite database immediately; an optional background queue replays mutations to a department server when connectivity returns.
• [Bulk and exception workflows] Mark everyone present then flip the absentees, or mark individuals — the marking model supports both without extra steps.
