Two kinds of clients: parents and college students
For high school chemistry, parents usually pay, often once a month. College students taking general or organic chemistry tend to pay for themselves, session by session, in cash or by transfer.
Squool handles both. Add a monthly payment to a student's balance with “Add Funds” and the lessons are paid one by one, oldest first. For a pay-as-you-go college student, open the lesson and mark it as paid. Either way, the week grid shows which sessions are paid and which are still owed.

Review groups before the big test
Three or four classmates reviewing equilibrium or stoichiometry together make one group lesson. Each student keeps their own price, so a friend who joins at a discount is no problem, and payments and missed sessions are tracked per student.
Give the group a name and a color, such as “AP Chem Thu”, and move or cancel the whole group in one step when the exam date shifts. Before each group lesson you get one reminder, not four.

Midterms, finals and quiet weeks
College chemistry has a calendar of its own: midterms in October and March, finals in December and May, and almost nothing in between semesters. Add single extra sessions before exams in free hours of the grid, without touching the weekly schedule.
When the semester ends, archive the student. Any money they paid ahead returns to their balance, and when they come back for Organic Chemistry II, you return them from the archive and choose which of their old days are still free.

See which months actually pay
The month ring shows what you earned, what's due, what's still upcoming and what was lost to cancellations. Tap a student to see which sessions make up the total, and compare one month with the next — useful when half your income depends on exam season.
The business side, not the chemistry
Squool has no whiteboard, no practice problems and no video calls — you keep your usual tools for the lesson. It's built for one tutor, not a tutoring center with several teachers, and it doesn't send invoices.
It runs on iPhone, iPad and Mac, syncs through your own iCloud and keeps your data on your devices; the developer can't see it. Full access is free for 14 days, no card needed.
Questions and answers
What app do chemistry tutors use to schedule sessions and track payments?
Squool covers the weekly schedule, each student's balance, group review sessions and monthly income on iPhone, iPad, Mac and Apple Watch. It's free to try for 14 days.
Can I run a chemistry review group with a different price for each student?
Yes. In a group lesson every student has their own price, and payments and misses are marked per student.
How do I handle a college student who only comes before exams?
Add one-time sessions when they book, and archive the student between semesters; their history and any prepaid money stay.
Can I see how much I earned from chemistry tutoring each month?
Yes. The month ring shows earned, due, upcoming and lost income, and you can compare months.
Does Squool include practice problems or a periodic table?
No. Squool is for your schedule and payments, not for lesson content.
