Eliminate Attendance Risk,Master Your Courses

Based on your university regulations or course-specific limits (20%, 30%, or custom hours), the system calculates your total and remaining allowances. When your remaining margin is safe, it shows Green; as limits approach, Yellow; and when you are at risk of failing, Critical Red alerts notify you immediately.

Yes! In universities, theoretical lectures (typically 30% allowance) and practical/laboratory sessions (typically 20%) have distinct limits. Derslerim lets you define theoretical and lab hours per course and tracks each quota independently.

Thanks to Derslerim’s "Exception Management", you can log temporary classroom, room, or hour shifts without disrupting your master recurring timetable. A colorful banner alerts you on that specific day, and future weeks automatically remain unchanged.

You can mark any session as canceled for that week or add weekend/evening make-up sessions as one-time exceptions. This ensures your weekly schedule stays accurate and attendance quotas are calculated correctly.

It is an integrated assistant for students who prefer typing over navigating complex menus. You can chat naturally with prompts like "I missed Calculus today", "Show my attendance summary", "What classes do I have tomorrow?", or "Undo my last attendance", and the assistant executes the task in seconds.

Yes! Both inside the assistant chat and on the course detail screen, you can tap "Undo" with a single click. Accidentally recorded absence hours are immediately restored to your quota pool.

It is a dedicated focus mode for midterm and final exam periods. During exam week, routine weekly lectures are temporarily hidden, putting your countdown timer, exam dates, times, rooms, and test notes in the spotlight.

Yes! Derslerim is built with a strict offline-first architecture. It functions completely without an internet connection in lecture halls, basements, subway lines, or libraries.

Never! We follow a strict zero-data-collection policy. No registration, email, or passwords required. All your classes, notes, and attendance logs are stored exclusively in your device's local SQLite database; no one—including us—can access your data.

No. When national public and religious holidays are synced with your academic calendar, courses falling on those dates are automatically exempt from absence calculations.

You can receive local device reminders (15 min, 30 min, 1 hour before classes or exams). You can also set Do Not Disturb (DND) quiet hours so your phone remains silent while studying in libraries or sleeping.

If a course meets on Monday for 2 hours and Wednesday for 2 hours, you can add multiple day/time slots under the same course. The app automatically calculates the total weekly hours (4 hours) and computes your absence limits accordingly.

Yes. You can choose a standard university-wide regulation percentage or customize specific quotas (by percentage or exact hours) for individual courses per instructor requirements.

When a term ends, the Semester Reset Wizard lets you archive completed courses with one tap. Your past grades and attendance history remain safely stored, while giving you a fresh, clean timetable for the new semester.

Derslerim’s core features are completely free and free of intrusive, full-screen ads that break your study focus. Our mission is to provide university students with the cleanest and most focused academic tool possible.
