    01Every racket

    How every job runs.

    Take the racket in, record tension and string, mark it done. It all lives in the job, and the reel keeps count by itself.

Why not just use a spreadsheet?

Because a spreadsheet only stores what you type into it. It does not do the maths with you and it does not remember.

With the spreadsheet

  • Next time you go hunting for what that person had last.
  • How much is left on the reel is measured or guessed.
  • Unpaid amounts live on a note beside it.
  • On a phone in the hall the file is unusable.
  • Whoever saved last wins.

With Stringcourt

  • Tap the name — racket, tension and string are already filled in.
  • The remaining length keeps itself up to date and speaks up before it runs short.
  • Paid or not sits on the job itself.
  • Built for the phone, not just shrunk to fit.
  • The same state on every device you use.

Why Stringcourt exists

Built by someone who strings rackets.

Stringcourt is not a corporate product but a tool from the everyday life of a stringer and official. It started as a spreadsheet. Today it holds what you actually need: tap a name, tension and string are already there, the reel keeps count. Missing something? Say so on the feedback board.
