Used for reminders and calendar alarms.
Your planner is kept only in this browser (local storage).
Add your classes first, each with a colour, teacher and room. Then fill in the timetable: one entry per lesson, with the day, start and end time. Homework, projects, exams and tasks can belong to a class, have a due date (and a time if it matters), a priority, a checklist of steps and notes. Today shows your lessons and what's overdue or due soon; Week and Calendar lay the same things out by day; Tasks lists everything with filters.
Yes. Turn on the two-week timetable, say whether this week is Week A or Week B, and mark each lesson as every week, Week A only or Week B only. The weeks then alternate on their own, including in the calendar file.
Give a task a reminder (at the due time, or 15 minutes to a week before). With notifications switched on, the browser shows them while homework.gripe is open in a tab; a web page can't wake itself up once it's closed without a push server, and there isn't one. For reminders that always arrive, especially on a phone, use "Add to my calendar": it saves an .ics file with your homework and exams as events with alarms (and, if you like, your timetable as repeating events) that you open in Apple Calendar, Google Calendar or Outlook. Importing a new copy later adds a second set, so delete the old one first.
In this browser's local storage on this device, and nowhere else. There's no account and nothing is sent to a server. It doesn't sync between devices: export a backup to move it to another browser or keep it safe, and import it there. Clearing this site's data in your browser deletes it. Like every gripe tool, the page counts visits with Cloudflare Web Analytics, which never sees what's in your planner; see Terms & Privacy.
Yes, with no ads, no sign-up and no paid tier. The classes, timetable, progress view and calendar export are all included.
