Helium

Is Helium free?

Yes. A passion project, free for everyone. Supporters like you are what make that possible, covering real costs like hosting and app store fees. Helium is also open source on GitHub — technical contributors welcome if you'd like to help out.

Does Helium have ads or share my data?

No ads, no data sales. Helium is open source funded entirely by Patreon supporters — keeping it free, ad-free, and yours.

Is Helium for every academic level?

Yes. Middle school, high school, college, university, grad school, homeschool — Helium fits every kind of student.

What devices can I use Helium on?

Helium has native apps for iOS and Android, plus a web app that runs in any modern browser. Sign in once and your schedule comes with you to every device.

Can I use my Google or Apple account?

Yes. Sign in with your existing Google or Apple account — no separate password to manage. Email and password sign-in is also available if you prefer.

Can I bring my Google or Apple calendar into Helium?

Yes. Subscribe to your Google calendar, your Apple calendar, your school's calendar, or any other calendar. External Calendars show alongside your Helium schedule.

Can I send Helium's calendar to other apps?

Yes. Helium's Feeds let you share private calendars of your events, assignments, and class schedules with Google Calendar, Apple Calendar, or any other calendar app.

Can I take my data with me, or import it from another app?

Always. Export your full schedule as JSON — classes, grades, notes, events, reminders — anytime. The same format powers Helium's import, so you can migrate from another planner, restore a backup, or build an integration that automatically imports from a syllabus or course outline. Our import guide has more information, and the API docs are where the magic happens.
