Sigma is named after the Σ in the GPA formula — because we actually calculate it right. Unlike other apps that simply average your grades, Sigma weighs each course by credit hours, giving you the same GPA your transcript shows. ▸ CREDIT-WEIGHTED GPA The formula your transcript uses, finally in an app. • Proper weighting — your 4-credit Calculus matters more than your 1-credit seminar • Per-class grading scales — set A/A-/B+ or A/B/C for each course independently • Semester and cumulative GPA — track both, see the breakdown • Real-time updates — your GPA recalculates as you enter grades ▸ TRACK EVERY ASSIGNMENT Stay on top of your classes with organized grade tracking. • Weighted categories — Exams 40%, Homework 30%, Labs 20%, Participation 10% • Drop lowest grades — configure per category • Extra credit support — calculate your real score • Quick entry — add assignments in seconds ▸ WHAT DO I NEED? Stop guessing what score you need on your final. • Set your target grade — pick a letter or percentage • See exactly what you need — on remaining assignments • Know when it's impossible — no false hope, just math ▸ WIDGETS FOR YOUR HOME SCREEN Check your GPA without opening the app. • Small widget — current GPA at a glance • Medium widget — GPA plus your lowest-graded course • Large widget — all courses with current grades • Lock screen — see your GPA instantly ▸ PRIVACY FIRST Your grades are your business. • iCloud sync only — through your personal Apple account • No tracking — we don't collect analytics or location • No ads — ever • Offline-first — works without internet ▸ PRICING FREE: • 6 classes (a full semester for most students) • Full credit-weighted GPA calculation • All assignment tracking features • iCloud sync across devices PREMIUM SUBSCRIPTION Sigma Premium is available with the following subscription options: Premium Monthly: $4.99/month Premium Annual: $29.99/year (Save 50%) — includes 7-day free trial Premium unlocks: • Unlimited classes and semesters • Home screen and lock screen widgets • Export to PDF and CSV • Custom themes and app icons • Priority support Payment will be charged to your Apple ID account at confirmation of purchase.
