Attendance tracker and bunk calculator in one — Bunku tells you exactly how many classes you can skip while staying above your attendance percentage. No login, no ads, 100% offline. Stop guessing whether you can miss a lecture — know it to the class.

Never get debarred for low attendance again. After each class just tap Present or Absent and Bunku does the maths for you: how many classes can I bunk, and how many do I need to attend to get back above 75%? It's the smart, subject-wise attendance calculator built for college and university students.

★ HOW IT WORKS
1. Add your subjects and set a minimum attendance percentage for each (75% rule? done).
2. Tap Present or Absent after every class — no semester totals to type in, ever.
3. Bunku instantly shows your live attendance percentage, your safe-to-bunk count, and how many classes you need to attend to recover. That's it.

★ WHY STUDENTS CHOOSE BUNKU
• Smart bunk calculator — see how many classes you can safely bunk per subject, instantly, without falling below your target.
• Counts from YOUR logs — it never asks you to type in semester totals like other attendance apps. Just mark present or absent and it tracks everything.
• Works like a smart digital attendance register — track daily attendance subject by subject and Bunku does the percentage maths for you.
• Subject-wise attendance — set your own minimum % (75%, 80%, or whatever your college needs) for each subject.
• Colour-coded status — Safe, Warning, At Risk — so one glance tells you exactly where you stand.
• Fix a missed day in two taps and backfill classes you forgot to mark.
• Joined mid-semester? Enter your starting totals once and carry on.
• A genuinely clean, distraction-free dark interface — built dark-first, not a broken afterthought.

★ NO ADS, EVER
Most attendance apps bury you in ads. Bunku shows none — free or Pro. Your screen stays yours.
