Helium
What it is
Helium is a free planner for organizing classes, homework, grades, notes, and academic workload. Its grade tools calculate results in real time, let users try hypothetical scores, and estimate what is needed on a final to reach a target grade. Scheduling offers Month, Week, 3-Day, Day, and Agenda views, with color coding, filters, search, and drag-and-drop scheduling. Reminders for assignments, classes, exams, and events can arrive as push notifications on iOS, Android, and web, or by email. Two-way calendar syncing supports Google, Apple, other calendars, and iCal sources. Notes can include headings, lists, quotes, links, and search, and can be connected to classes or assignments. Helium is open source, and its public REST API covers actions available in its iOS, Android, and web apps. It does not maintain official integrations or pre-built tooling, though users can build integrations with the API. Users can access, export, or delete their data, and full schedules can be exported as JSON. User data is stored and processed in the United States.
