Also available on iOS & Android
Same schedule, in your pocket. Sign in once and your data follows you across every device.
Not just a planner. A study buddy that actually helps.
Helium organizes and color-codes your schedule, does the math, and surfaces what matters most — so you can focus on the actual learning.
Calculates what grade you need
Use the What Grade Do I Need? calculator to see exactly what you need on the Final to achieve your desired grade.
Shows your pace
Progress vs. Pace shows whether you're Ahead, On Track, or Behind — work done vs. time elapsed in the term.
Surfaces at-risk classes
At-Risk Classes appear at the top of your dashboard whenever a class slips below the threshold you set.
Nudges, never nags
Native push on iOS, Android, and web, or email — before assignments, classes, and exams sneak up.

Subscribe to Google, Apple, or any other calendar — it shows up in Helium. Or share Helium back the other way.
Travels with you
Native iOS and Android apps. Web in any browser. Your schedule stays in sync on every device.

Smart Calendars
One planner. Every view.
The Home Base.
Your schedule shouldn't be scattered across apps, a stack of syllabi, and sticky notes on your laptop. Helium keeps your classes, assignments, and personal events in one color-coded Planner. Use Month for the long horizon, Week for the academic rhythm, Day for what's right in front of you, Agenda when you need your schedule listed.
Pick your own colors — by class, by assignment type, and more — and toggle between Light and Dark mode. Filter or search to drill into a busy view. Everything you need to stay sharp.
Your personal calendar still has its place. Pull in Google, Apple, or any iCal source alongside your Helium schedule — or push Helium back the other way.
Live Grade Tracker & Calculator
Know your grade, and know what's next.
The Bottom Line.
Done with the spreadsheet? Us too. Helium recalculates your grades in real time — by class, by category, and across the whole term — however your professor grades. The dashboard surfaces your overall grade, At-Risk Classes, Progress vs. Pace, and Pending Impact (where your ungraded work is piling up) at a glance, so you always know where your attention is most needed next.
Drill down into any class to see how every category contributes — essays, quizzes, labs, exams — and precisely where the points are coming from. Need to know what you have to score on the Final? The What Grade Do I Need? calculator can show you.
Rich Notebook
Notes that know what they're about.
The Backstory.
Your Notebook can hold notes for anything in Helium — and each one knows what it's about, so the rubric, the lecture summary, or the half-written outline is always one click from what it relates to. Need to draft a paper or jot down lecture notes that aren't tied to anything yet? Standalone notes let you capture that too.
Notes can be formatted just like you would a doc — headings, lists, quotes, and links — so they read the way you think. Search across everything you've written, and print any note when you need a hard copy.
At-a-Glance Schedules
Your day-to-day, hour by hour.
The Brass Tacks.
Zoom in to your week, hour by hour. Class meetings are time-blocked — even when that varies day-to-day, like a Friday lab that runs longer than Tuesday's lecture.
Assignments show up exactly when they're due, so a glance at tomorrow morning tells you what you're walking into. Drag and drop to shift an assignment or event when plans inevitably change, and check assignments off right from the calendar.
Need more info on Wednesday's class, room number, teacher's email, or a refresh on the grading scale? Details are always just a click away.
Todos View
When the calendar isn't the right layout.
The Nuts & Bolts.
Detailed Assignment Planner
Every detail. One place.
The Nitty Gritty.
A title and a due date is enough for a quick to-do. Class, category, priority, Reminders, Attachments like the rubric, formatted Notes, and linked Resources are all there when a capstone project or exam deserves more thought.
Increase a paper to a higher priority and it floats to the top of your Todos view. Link the textbook chapter to the reading and the right materials are one click away when you sit down to work. For a weekly assignment, create it once, then clone it and reuse its template for the rest of the term.
