What students actually say
Unedited reviews from Google Play and the Microsoft Store.
“In my opinion this is the best app for any student I mean any student. If you are someone who is trying to organise your studies this is the best. Most importantly this app gives us a chart of our study time, it really displays how I study and motivates me to keep my study hours up.”
“Perfect app for me. I have tried making excel sheets before, but having a time tracker, countdown and syllabus checklist all in one is amazing and exactly what i wanted, lets me see how much time i have spend per chapter, which is really helpful for planning revisions.”
“Finally found an exam tracker app that matches what I was looking for. Simple, useful, and well thought out. The developer is approachable and continuously adding improvements too.”
“I feel no fear and tension or regret which I felt earlier for being imperfect, inefficient and doing procrastination. Thanks to this app that I have now everything organised.”

All updatesExam Countdown and Planner App – Built From My Real Exam Problems
Built from my own exam struggles, Exam Countdown and Planner was created to replace messy calendars, notebook markings, and manual day counting. A simple digital tool designed to help students track exams clearly, plan studies effectively, and prepare with confidence—without stress.
Why I Built AutoAttend: A Problem I Personally Faced
Barred from exams due to low attendance despite having no backlogs, I experienced firsthand how stressful and unclear attendance tracking can be for students. AutoAttend was born from that frustration—to make attendance automatic, reliable, and student-friendly.
