Squool for physics tutors

Long problem-solving sessions,
quick to keep track of

Updated November 15, 2026

Physics sessions run long: a free-body diagram, the kinematics problem it unlocks, then the one the student got wrong on the quiz. Many physics tutors also cover the calculus behind AP Physics C or college mechanics. Squool keeps the week, the 90-minute sessions and every student's balance in order on iPhone, iPad and Mac.

Long problem-solving sessions, quick to keep track of

90 minutes is normal in physics

An hour often isn't enough to get through a set of problems, so many physics tutors work in 90-minute blocks. Set each student's default lesson length once: presets cover 45, 60, 90 and 120 minutes, and “Other” takes any length you like.

Need a two-hour session before a test? Change the length or the price for that one lesson only, and the rest of the series stays as it was.

Labs in the fall, the AP exam in May

Labs in the fall, the AP exam in May

High school physics students usually start weekly in September with homework and lab reports. From March, AP Physics students often want two sessions a week until the exams in May. Add a second weekday to the same series, each with its own time, or change the schedule with “This & Future” so past sessions stay untouched.

Squool notices the change and gives the student a “More often now” achievement, while the 🔥 streak next to the avatar shows who hasn't skipped a week.

The engineering student who disappears for a month

College students vanish for spring break, internships or a heavy exam week in another class. Set a pause for just that student: their lessons in those dates are removed, and prepaid money is kept for the sessions after the break.

If they stop for good, archive them. Money paid ahead returns to their balance, and their full history is still there if they come back for Physics II.

Who still owes for last month

Who still owes for last month

The top of the student list shows who owes you and who has paid ahead; sort by debt to see the biggest amounts first. Each lesson in the week grid is colored by payment state, so an unpaid session from two weeks ago doesn't slip by.

Working at a table full of notes? Apple Watch shows the current and next session, and you can mark a missed lesson right from your wrist.

iPhone, iPad, Mac — your data stays with you

Squool syncs between your devices through your own iCloud, without any sign-up. Students, sums and earnings stay on your devices and in your iCloud; the developer can't see them. It's made for one tutor, and you can try everything free for 14 days, no card required.

Questions and answers

Is there a scheduling app for physics tutors?

Squool is a schedule and payment tracker for tutors working alone, on iPhone, iPad, Mac and Apple Watch. The first 14 days are free.

Can I set 90-minute sessions as the default for a student?

Yes. Each student has their own lesson length; presets are 45, 60, 90 and 120 minutes, and “Other” allows any length.

Can I pause a college student over spring break without losing their prepaid sessions?

Yes. A pause removes their lessons for those dates, and the prepaid money goes to the lessons after the break.

Does Squool work on a Windows laptop or Android phone?

No. Squool is only for iPhone, iPad, Mac with Apple silicon and Apple Watch.

Can I see a list of students who owe me money?

Yes. Owed and prepaid amounts are shown at the top of the student list, and you can sort students by debt.
