Helium

Helium is a student planner and academic calendar that helps you track classes, assignments, grades, and notes in one color-coded place. View your schedule by month, week, day, or agenda, and sync with Google or Apple calendars to keep everything aligned.

Helium recalculates grades in real time, highlights at-risk classes, and shows progress versus pace so you know what to tackle next. Use reminders, a focused Todos view, a rich notebook, and the What Grade Do I Need? calculator across web, iOS, and Android. It’s free and open source.
