Kajet is a student planner for school and university: timetable, grades, homework, tests and studying in one app. No account, no ads, and your data stays on your iPhone and iPad. TODAY β’ "This week" rings: your weekly average with an up or down arrow, and how many assignments and tests are behind you. β’ Your day as a timeline: lessons in subject colors, breaks and free periods, the lesson in progress and the minutes left in it. β’ "To do": the nearest test with a countdown, overdue homework and today's tasks that you check off with one tap. β’ Quick add for a grade, an assignment, a test or a study session. TIMETABLE β’ Day and week views, A and B weeks, rooms and times. β’ Cancelled lessons, substitutions and room changes for a single day. β’ After-school events: sports, music, tutoring, clubs, with a reminder of when to leave. β’ A Home Screen widget and a Live Activity counting down the lesson in progress. GRADES AND AVERAGES β’ A simple or weighted average with your own categories (quiz, test, oral answerβ¦), comments and retakes. β’ The average for each subject and overall. Leave out subjects that don't count. β’ Statistics: average over time, your best subject and the one pulling you down. FOR UNIVERSITY STUDENTS β’ ECTS credits, final grades and the ECTS-weighted average for each semester and overall. β’ Set your own scholarship threshold and see which grades you still need to reach it. β’ Winter and summer semesters, exam and re-sit sessions. HOMEWORK AND TESTS β’ Assignments, tests and quizzes grouped into today, tomorrow, this week and later. β’ Reminders a day or three days ahead, in the evening or at a time you choose. β’ Turn a finished test or assignment into a grade in one step. STUDY MODE β’ A study timer with modes of your own: a countdown, or Pomodoro with rounds and breaks. β’ Link a session to a test or an assignment and see how much you have studied for it. β’ Study history for 7 days, a month or a semester, with a breakdown by subject. β’ A Live Activity on the Lock Screen and in the Dynamic Island. AI TIPS (optional) β’ A short summary of your week and a hint on when to study, based on your grades, free periods and upcoming tests. β’ It runs entirely on your iPhone or iPad with Apple Intelligence, and nothing is sent to a server. Off by default, and it needs iOS 26 and a supported iPhone or iPad. SIRI AND SHORTCUTS β’ Ask for your next lesson, today's homework, your next test or your average, or add a grade, an assignment or a test by voice. SEMESTERS AND SCHOOL YEARS β’ Keep several school years and semesters. Start a new one by copying subjects, the timetable and events from the previous one. PRIVACY β’ No account and no ads. Your data stays on your device. Anonymous usage statistics and crash reports help us improve the app. GOOD TO KNOW Made with the Polish school and university system in mind (grades 1β6, the 2.0β5.0 university scale, ECTS), but usable anywhere. The AI tips are written in your language when Apple Intelligence supports it, and in English otherwise. Available in English, Polish, German, French, Spanish, Italian, Japanese, Chinese, Swedish, Norwegian, Czech, Slovak and Portuguese.

Verdict
The clearest difference is update cadence: Kajet at every 4 days against School Diary Plus's every 6 weeks. School Diary Plus's advantage is iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
