Attendex
A local-first self-attendance tracker
Overview
It started with a simple, frustrating problem: tracking my own attendance. Juggling subjects, gym sessions and a daily Leetcode streak, I kept asking: did I attend this class, and how many more can I skip before hitting the danger zone? Attendex answers that in one tap, and has crossed 700+ downloads on Google Play.
- A local-first app to track attendance for any subject or activity.
- A calendar view to visualise attendance trends.
- A dark mode toggle for night owls.
- An offline-first approach, so checking stats never needs internet.
