Attender vs UnivTrack

Attender has no write-up on Specifiction yet; its figures are above.

UnivTrack is a free, open-source attendance tracker for college and high-school students. It records attendance by course and shows live absence counts, highlighting courses that are nearing or over their limits. Users can create unlimited academic terms, choose custom names and start dates, and set each term to last from 5 to 18 weeks. Weekday schedules can include up to five morning and five afternoon course slots. For each class, users can mark Attended, Absent, or Holiday / No Class; long-press actions can update previous weeks in bulk. A term becomes read-only after its final week has passed. UnivTrack is an installable progressive web app with an offline app shell, home-screen icon, and full-screen mode. It runs on Android, iOS, Windows, macOS, and Linux, and includes English and Turkish translations with automatic browser-language detection. It uses Firebase Authentication and Cloud Firestore, with user data stored in the user's own Firebase project. Self-hosting requires configuring that project. The project says it has no third-party ads or tracking.
