SMART CALENDARS Color-code classes, assignments, and personal events across month, week, 3-day, day, and agenda views — and toggle between Light and Dark mode. Pull in Google, Apple, or any iCal calendar, or push Helium back out. LIVE GRADE TRACKER & CALCULATOR Helium recalculates your grades in real time — by class, by category, and across the term. The dashboard surfaces At-Risk Classes, Progress vs. Pace, and Pending Impact at a glance. Ask "What Could I Get?" to project your final grade from how the rest of the term goes, or "What Do I Need?" to find out exactly what you need on the Final. RICH NOTEBOOK Write rich notes, linked directly to items in your Planner, so the context you need is always right where you need it. Or keep standalone notes for anything else, from lecture summaries to paper drafts. Format like a doc, search across everything, print when you need a hard copy. AT-A-GLANCE SCHEDULES Classes time-blocked hour by hour, including rotating schedules like A/B Day and Week A/B. Drag to reschedule, check off completed assignments right from the calendar, and tap any class for details — room, teacher email, grading scale. TODOS VIEW A focused checklist of your assignments. Sort and filter by class, priority, due date, or resources — organize your study time the way you want. DETAILED ASSIGNMENT PLANNER Class, category, priority, Reminders, Attachments like rubrics, formatted Notes, and linked Resources — every detail in one place. For a weekly assignment, create it once, then clone the template for the rest of the term. REMINDERS Reminders before assignments, classes, exams, or events — push notifications, or email if that's your style.
