Features
Read full description

Semestral keeps your coursework, exams, deadlines and grades in one place. A native app for Mac, iPhone and iPad. Set up semesters and modules the way your degree is actually structured. Tasks go on a Kanban board, dates in the calendar, grades on the module they belong to. YOUR SEMESTER ON THE BOARD • Tasks in To Do, In Progress and Done • Move them by drag and drop or from the context menu • Deadline with optional time, priority, notes and a reminder per task • Recurring tasks for weekly problem sets and routines, with an end date • View a whole semester at once or a single module CALENDAR AND EXAMS The monthly calendar shows task deadlines and exam dates together. Every module has its own colour, so you can see at a glance what an entry belongs to. Store exams with a date, optional time, room and duration, including for a module from another semester. A retake in the next exam period fits the same way the original date does. GRADES AND ECTS Record a grade on each module. Semestral works out your ECTS-weighted average from them, for Bachelor and Master degrees, broken down by semester. REMINDERS A daily notification at the time you choose tells you what is still due that day. The badge on the app icon shows overdue tasks, today's tasks, or both. ACROSS YOUR DEVICES Turn on iCloud sync and your semesters, modules, tasks, exams and grades stay the same on Mac, iPhone and iPad.

The call

The clearest difference is in-app purchases: Semestral at none against ChimeSet's 1. ChimeSet's advantage is update cadence (every 2 weeks vs every 4 weeks) and iOS requirement (18.0 vs 26.0). On price, ads and device support there is nothing between them.
