ChalkSpot.

Clubs are run by people who would rather be coaching. Registers get printed on a Monday, payments arrive in three different ways, and somebody spends their evening working out who actually turned up and who still owes for half a term.

A product is a different problem to a website. Every club's classes, families and money have to sit apart from every other club's and stay that way. Payments have to reconcile. It has to stay quick on gym wifi, and be obvious enough that a coach picks it up mid-session without being trained on it.

It also had to be worth the switch on day one, because nobody moves off a spreadsheet that mostly works.

Chalk is what gymnasts put on their hands. A spot is the place you have booked, and it is also what a coach does when they stand beside an athlete to catch them. ChalkSpot says the product and the sport at the same time, which is why it stuck.

The identity runs on a chalk lime and a near-black, with the O in the mark doubling as the spot. It is bright enough to read across a gym and calm enough to sit in an admin screen somebody stares at all week.

By default ChalkSpot is an embed. A club pastes it into the site they already have and their timetable and booking flow appear inside their own pages, styled to match. No migration, no rebuild, and nothing to argue about with whoever looks after their website.

Plenty of clubs get there and decide the site around it is the next problem. So a custom website is an add-on: same team, same brand work, built around the booking flow rather than bolted on beside it.
