Four recurring problems board members across Germany describe to us.
Member list in Excel, sign-ups by email, direct debits tracked by hand: every change has to be made in several places at once.
Members ask about free slots over WhatsApp while courts sit empty, because nobody can see real-time availability.
New members know an app from their bank or gym. A club that only offers a notice board and a phone list loses them to the club next door.
No app, no online booking, no up-to-date information for members, while the club next door has had this for years.
17.5%
of sports clubs in Germany see their existence at risk, mostly because nobody steps up to handle administration and organisation.

A data protection risk for the board
Member data in private WhatsApp groups or on a board member's laptop is a personal liability issue if something goes wrong, not just a convenience problem.
Members, court occupancy, fees and communication come together in a single interface, instead of spreadsheets, group chats and three separate tools.
Over 100 members download the app in the first week, across every age group.

“We finally have everything in one place – it saves us a huge amount of time and makes organising things so much easier.”
“I didn't think I'd actually use it – but it's really simple and genuinely helpful.”
“All the info, dates and news – I'm always up to date. Great thing.”
Three core modules solve the biggest pain points. The rest is there when you need it.
