Groups where everyone pays differently
In Squool, a group lesson holds several students, and each one has their own price: the siblings pay less, the new kid is on a trial rate. Payments and missed lessons are marked per student, so one family's debt doesn't get lost in the group total.
Name the group and give it a color, like “Juniors Sat 10:00”. When the pool is closed or the tournament moves, reschedule or cancel the whole group at once.

Session packages for private clients
A personal training client buys ten sessions up front; in Squool, they're a student and the sessions are lessons. Add the payment to their balance with “Add Funds”, and each lesson is paid automatically as it happens, oldest first. The student's card shows how many lessons are still prepaid; when the package runs out, the student appears in the “Owed” list at the top.
Students who pay per lesson? Mark the lesson as paid when they hand you the money.

No-shows and cancelled sessions
A no-show without warning is marked as missed and charged, like a lesson that took place. A lesson cancelled in advance isn't charged, and prepaid money returns to the balance for the next one. Cancelled lessons appear in your statistics as lost income, so you can see what a rainy week or a holiday weekend cost you.
On the court, at the pool, from your wrist
Coaches rarely stand at a desk. Apple Watch shows which lesson is on now and what's next, and lets you mark a miss or cancel a lesson with a tap; complications put it on your watch face. A reminder arrives before every lesson, and a group lesson gets a single reminder with everyone in it.
Home Screen widgets show your next lessons, and the full schedule is on iPhone, iPad and Mac.

Reward the athletes who keep showing up
Squool gives students achievements automatically: “Every week” for not skipping a week, “Iron discipline” for three months without a miss or cancellation, “Heart of the group” for four weeks without missing a group lesson. A 🔥 streak next to the avatar shows how long someone has kept going.
Each student's statistics show a month calendar with every lesson, what was earned, due and lost, and a comparison with last month.
Built for one coach, not a club
Squool is for a coach working alone. It isn't club management software: there are no accounts for several coaches, no member booking, no online payments or invoices. Your data is stored on your device and in your own iCloud, and the developer can't see it.
The first 14 days give you full access for free, without a card.
Questions and answers
What's a good app for a chess coach to schedule lessons and track payments?
Squool handles one-on-one and group lessons, a balance for each student and monthly income, on iPhone, iPad, Mac and Apple Watch. It's free for 14 days, no card needed.
Can siblings in the same group pay a different price?
Yes. Every student in a group lesson has their own price, and their payments and misses are tracked separately.
How do I track a personal training package of 10 sessions?
Add the package payment to the student's balance. Each lesson is paid automatically as it happens, and the student's card shows how many are still prepaid.
Can I mark a no-show from my Apple Watch?
Yes. On Apple Watch you see the current and next lesson and can mark a miss or cancel with a tap.
Can clients book sessions themselves?
No. There's no booking for students and no online payments; you manage the schedule and record payments yourself.
Does Squool work for a gym or club with several coaches?
No. Squool is for one coach; it has no shared accounts for a team.
