About this app

TEACH. WE HANDLE THE REST.

SIGMA helps teachers and tutors manage lessons without the admin burden.

PLAN LESSONS WITH EASE
Create one-time or recurring lessons in seconds. Weekly, bi-weekly, or monthly schedules are easy to set up and adjust.

MANAGE STUDENTS SMARTLY
Keep all your students in one place. View lesson history, notes, attendance, and upcoming sessions at a glance.

FULL ATTENDANCE CONTROL
Mark attendance quickly: attended, absent (charged or not), make-up, or canceled. No pop-ups, no friction.

CLEAR INCOME TRACKING
Track payments and balances clearly. See who paid, who didn’t, and understand your income over time.

STAY FOCUSED
SIGMA highlights what needs attention today so you can focus on teaching, not administration.
