Built by a squash coach, for any racket sport

Put a poster on the club wall, or the link in your WhatsApp group. Players pick an hour you’re free and get a reminder the day before. There’s nothing for you to send.

Then £15 a month, or £12.50 a month billed yearly (£150).
How it works
Set it up once. Lessons arrive three ways. Everyone’s reminded.
Your regulars
Booked in automatically, a month ahead. Nobody has to do a thing.
Players book themselves
From the poster on the club wall, or the link in your WhatsApp group.
Someone rings you
Add the lesson in seconds. It won’t let you double-book.
Everyone gets a reminder the day before
An email 24 hours before, with the time, the venue and a link to cancel if they cannot make it.
Where it comes from
Made on court, not in a meeting
I coach squash every week, so I built Coach Diary to solve my own problems. Every lesson I teach runs through it. It exists because the same problems kept coming back. A regular would forget it was Tuesday. A court I’d paid for would sit empty. Money I was owed would live only in my head. And those were just a few of them.
Every feature is there because I needed it as a working coach, not because booking software is supposed to have it. I rely on it every week, and I keep improving it. If something you need is missing, tell me — I might well build it.

A look around
Built around the way a coaching week actually runs
The booking page
Players book themselves, from any phone
Each club gets its own page. Players pick a free slot from any phone, with no account to make.
The reminder
The day before, every player is reminded
Twenty-four hours before, every player gets an email, and one tap cancels if they can’t make it.
The poster
A poster on the noticeboard does the marketing
One A4 poster per club, with your words, your number and a QR code that opens that club’s page.
Regulars
Your weekly players, booked in without the admin
Tap a slot and pick the player. Their lessons are booked a month ahead, reminders included.
The money picture
Know who has paid and what a venue really earns
Mark who has paid and what each court cost you, then see what every club really earns. The app records money; it never takes any.
Everything it does
The full list, in plain words
It suits any coach who teaches one person or a small group at a set time — padel, tennis, badminton, pickleball, or anything else played on a court.
Your week
Set once, then it fills itself.
- Weekly times per venue, with length, price and places
- Group sessions — set the places, players book their own
- Time off for holidays and matches, or one slot at a time
Bookings
The part that keeps working while you are on court.
- A booking page for each venue
- Printable QR posters naming your sport, with your photo, number and words — different for each club if you like — drawn as you type
- Add a lesson by hand when someone rings — it won’t let you double-book yourself at two clubs
Regulars
The same players, every week, without writing them out again.
- Weekly players booked in automatically, a month ahead
- Regulars get the same 24-hour reminder
- Two regulars on one slot, the price shared between them
Money
A record of it. The app never handles any.
- Mark who has paid you — on which day, and by which of your own methods
- Earnings added up over any range, by venue, lesson type and how you were paid
- Tell players how to pay you, in every confirmation and reminder
Players
Booking never needs an account. Their own page is there if you offer it.
- Book and cancel with just a name and email
- Invite a player to see their history and your shared notes
- One account for a parent managing several children
Records
What you would otherwise be keeping in your head.
- Every player on a page of their own, with their lesson history
- A private note per lesson, shared only if you choose
- No-shows in one tap, counted for you — never shown to the player
The honest bits
- It does not take payments
- You mark who has paid; collecting it stays between you and the player.
- What it costs you
- One plan, monthly or yearly, after a card-free trial. Cancel any time.
- Your players don’t have to change anything
- Regulars with an email address just start getting a reminder the day before. Anyone who books needs only a name and an email.
- There is no app to download
- It’s a web page that opens on any phone.
- The calendar feed is one-way
- Lessons show in your calendar; nothing comes back the other way.
- Your diary is backed up every night
- A locked copy is made every night, stored separately from the app, and kept for 30 days.
Put next week’s lessons in and see how it feels
Add a venue, your weekly times and your regulars. Their lessons go straight in, and each gets a reminder the day before.
- Free for 30 days
- No card needed
