If you run the club
Everybody signed in sees the sheet. Anyone with the club's web address can see it too, with no names on it. They see which courts are free, which are taken and what the club has blocked out, and nothing about who. Signing in puts the names back. If your club would rather nobody outside saw the sheet at all, untick the box under Set up, in the section about what a member may book. Booking needs your name on the club list, because a booking is a name against a court. A sign-in called Secretary or League owner is a job rather than a name. If that is you, the screen says so and there is a button on it. Put your own name on the list once, and you book like everybody else from then on. A name the list already has is the one case it will not do on its own, because that is somebody else's record. Whoever runs the club points your sign-in at it from the Roles screen.
What the club sets up
Whoever runs the club presses Set up on that screen, and it is five sections along the top. Those are the courts and their names, when the club is open, peak times, what a member may book, and taking a court out. One at a time, so a club with eight courts reads its list rather than scrolling past four other forms. Back to the sheet is in the corner, and so is your phone's own back button. Set up and History are places, so going back off one lands on the day you came from.
How far ahead the sheet goes and how many bookings one member may hold at a time are under Booking limits. Today's bookings never count against that limit, so a quiet Tuesday is a free-for-all.
Say what each court is. Every court on that screen has its name, what it is made of and what is played on it, and a Save beside it. Rename one whenever you like: the name is what everybody reads on the sheet, not a code. The surface then shows under the court on the sheet and on the confirm, so somebody picking between two free courts can tell the artificial clay from the tarmac. Both are optional and neither says a word anywhere until you fill it in. The game is for the club that runs more than one. Put Padel on the padel court and the sheet says so. A tennis court at a tennis club stays quiet about it.
Peak times are two ranges: one for Monday to Friday and one for the weekend. Type the hours your club actually charges more for, and leave a row blank if none of those days is peak. For now they are a marker on the sheet and the limit on how many peak bookings one member may hold at once. They are what peak prices will hang off later.
