Summary

Helium is a free student planner for organizing classes, homework, grades, notes, and academic workload. Its grade tools update calculations in real time, let students try hypothetical scores, and estimate what they need on a final to reach a target grade. Scheduling views include Month, Week, 3-Day, Day, and Agenda, with color coding, filters, search, and drag-and-drop. It can send push notifications on iOS, Android, and web, or email reminders for assignments, classes, exams, and events. Two-way calendar syncing works with Google, Apple, other calendars, and iCal sources. Notes support headings, lists, quotes, links, search, printing, and connections to classes or assignments. Helium is open source and has a public REST API covering actions in its apps, though it offers no official integrations or tooling. Students can access, export, or delete their data; full schedules can be exported as JSON. User data is stored and processed in the United States. Helium identifies students from middle school through graduate school, along with homeschool students, as its audience.
