Square64 · for professional chess coaches
See how your students think between lessons
Puzzle homework that replays every arrow, wrong try, and second - plus the lessons, sparring, and payments around it.
Square64 is the dashboard for professional chess coaches: assign puzzle sets and timed racers, spot each student’s weak themes, schedule on Google Calendar, and track direct payments with 0% platform fees. Not a training app. Not a generic scheduler.

The part I open after every homework is the analytics. I can see how a student actually thought through the position, not just whether they got it right, so it’s much clearer where their play is weak before the next lesson.
Chess coaching deserves better than duct tape
You teach chess - you should not spend evenings reconciling calendars and chasing payments.
Scattered tools
Lessons in Google Calendar, students in a spreadsheet, puzzle PDFs in email threads, and payment status in your head.
Admin after teaching
Chasing unpaid lessons, resending Meet links, following up on homework, and checking who still needs to be scheduled.
Generic tutoring software
Most schedulers ignore the unique rhythm of chess coaching - sparring, separate rates, puzzle homework, and direct payments.
How it works
Get set up in minutes - then run your week from the dashboard.
- Step 1
Sign in and sync your calendar
One Google sign-in. Lessons and sparring land on your Google Calendar, and your busy times flag conflicts before you book.
- Step 2
Add students and set availability
Build your roster with lesson and sparring rates, set working hours, and publish your public profile when ready.
- Step 3
Schedule and track sessions
Book lessons, sparring, or weekly series from your calendar. Get Meet links, track payment status, and send branded student emails.
- Step 4
Assign homework
Create a themed puzzle set or timed racer sprint, share the student link, and review how they solved - including arrows and circles - before your next session.
Everything you need to run a coaching practice
From spotting a weak theme to the next lesson - one workflow.
Homework review
Open results for puzzle sets and racers before the next lesson - not only right or wrong.
- Timeline of marks, wrong tries, and timing per puzzle
- Board arrows and circles replayed as the student drew them
Puzzle sets & timed racers
Curated puzzle sets or a clocked racer sprint. Preview, swap, then assign via link or email.
- Mix themes or require all of them on one puzzle, with a rating band and quantity
- Review past mistakes or skip puzzles a student already received
- Students play from a link - no account required

How Square64 uses Google
Coaches sign in with Google and connect Google Calendar so Square64 can create, update, and remove lesson and sparring events on their calendar, attach Google Meet where the product supports it, and check for conflicts and busy times.
Square64 does not sell Google user data or use it for advertising. Students and parents do not sign in with Google.
