What Dink does for your club

Everything your bookings can tell you.

Dink reads the data you already have. It finds what needs your attention, then helps you act on it. Here is the real app on a sample club.

Daily Briefing

Start each day with a short, ranked list.

Each morning, Dink ranks what needs you: open courts to fill, events to promote and players to call. Every item opens the detail.

  • Open courts for the next two days
  • Fading regulars, ranked by impact
  • Court use for each day and time slot
The DinkBrain Briefing page: key numbers, open courts to fill, court use by day and time, and a note from Dink.
Sample facility · Example data
Fading players

See who is fading before they are gone.

Dink learns how often each player usually comes. When a regular is late by their own pattern, Dink tells you. It also sees when a whole group fades together.

  • Based on each player's own rhythm, not one rule for all
  • A suggested next step for each player or group
  • Ask your AI to draft the win-back notes
Two fading members. Each card shows their usual rhythm, the friends who also stopped coming, and Dink's suggested action.
Sample facility · Example data
Revenue heatmap

Find the empty slots that cost you money.

See court use and revenue for each day and time slot. Cash flow comes from the payments you captured in CourtReserve. Dink never fills a past month with a guess.

  • Use and revenue for every slot
  • Cash flow from captured payments
  • Forecasts only for the months ahead
The revenue heatmap: court use and dollars per slot for each day of the week, colored from quiet to busy.
Sample facility · Example data
Game night

Put a tablet on the court. It runs the night.

The kiosk loads your event roster from CourtReserve. Players score their own games and the standings update live. A walk-in joins with one tap.

  • Round robin, Swiss, Americano and King of the Court
  • Rotating, fixed or mixed partners
  • Medal rounds and brackets that seed themselves
The scoring kiosk during round 2: a round timer and court 3 with a live score.
Lobby TVs

Your lobby TV, always current.

Show the schedule, live courts, standings and the player of the day. Pair a TV with a short code. It also works on older smart-TV browsers.

  • Live courts and standings during events
  • Court hours leaders and the player of the day
  • Birthdays and member anniversaries
A lobby TV display: court hours leaders, the player of the day, birthdays and anniversaries.
CourtReserve, both ways

Read from CourtReserve. Write back when you say so.

DinkBrain syncs your CourtReserve data through the day. When you approve it, DinkBrain pushes event rosters into CourtReserve, or adds a new player as a CourtReserve member from your phone.

  • Hourly sync during the day
  • Push rosters to CourtReserve events
  • Add a new member from your phone
  • Players register and pay in CourtReserve from an invite
