Attendex: Attendance App

It all started with a simple yet frustrating issue—tracking my attendance. As a student juggling multiple subjects, gym sessions, and even my daily Leetcode streak, I constantly found myself asking, Did I attend this class? How many more can I skip before hitting the danger zone?

Building Attendex: A Self-Attendance Tracker

The idea was straightforward:

A local-first app to track attendance for any subject or activity.
A calendar view to visualize attendance trends.
A dark mode toggle for night owls like me.
An offline-first approach so that I did not need internet access every time I checked my stats.

Tech Stack

React Native with Expo – Fast and easy mobile development.
AsyncStorage – Ensuring everything is stored locally.
ShadCN & Tailwind – Clean UI with smooth dark mode support.

Core Features of Attendex

📅 Calendar View

I wanted a color-coded calendar where:

🟢 Green – Present
🔴 Red – Absent
🟡 Yellow – Special cases (e.g., Duty Leave)

🚀 Fast Attendance Marking

With just one tap, I can mark my status for the day. No extra confirmations, no delays.

🌙 Dark Mode Support

Because lets be honest, dark mode is life.

📊 Overall Stats

The app calculates and displays attendance percentage for each subject/activity in real-time, ensuring I stay above the required limit.

🚀 Now Available on Google Play!

After testing and iterating, I finally decided to release Attendex for others who might find it useful. Check it out and never lose track of your attendance again!

What’s Next?

✅ Add cloud sync for multi-device access.
✅ Integrate with Google Calendar for reminders.
✅ Enable custom reminders for low attendance warnings.

Final Thoughts

Sometimes, the best solutions come from personal frustrations. Instead of waiting for a better system, I built my own. Attendex is now my daily companion, keeping my habits in check while making attendance tracking effortless.
