How many days until the exam? What should you study today? StudyCal is a study calendar that turns your plans into today's to-do list. Check a plan off and your study time adds up automatically. Exam countdowns, home screen widgets, a streak heatmap, a focus timer and more than 50 achievement badges are all included. No sign-in needed. With Pro+, you can reschedule missed plans in one tap, see your pace toward exam day, sync between iPhone and iPad, and share your progress with a parent. StudyCal brings your study plans, timetable, to-do list and study time tracking together in one simple app for middle school, high school and exam students. Plans you add appear on that day's to-do list, and a single tap marks them done. Subjects are color-coded, and your study time is shown in charts. ■ Made for - Students who want to keep studying every day - Anyone tired of using separate apps for a timetable and a to-do list - Students preparing for exams who want to see time spent on each subject - Anyone who wants to add weekly recurring classes in seconds ■ Main features - Today's to-do: today's study plans in one list, with your completion rate at a glance - Calendar: switch between month, week, day and list views in one tap.
