This application provides Waterpolo venue infrastructure for running a game, it provides:
Shot Clock displays,
Game Clock displays,
Game Clock console, and
an Electronic Scoresheet.
Wait a minute how can one IPad do all that at the same time ? It cant, this a multiIpad application!
It runs each function executes on separate iPads, that all interact via some available network, preferably a WiFi network, cooperatively to provide synchronised time displays. you would need 5 iPads to run a full game support suite.
It also provides database application to enable you to manage an entire waterpolo completion or season, you can create a draw for a division of teams, schedule the draw at venues, publish the draws, publish the results, publish divisional points ladders, publish player stats, edit the players who play for clubs in teams in divisions. In reality it is a very complex database application, and basically you have to manage seasons my way, although there is a lot of flexibility. Seasons are assumed to have a game cycle which is either weekly which suites most inter-club competitions, daily which might suit a international competition, or continuous which would suit an age championship held over a long weekend. Divisions can have a home venue for all games, split games across multiple venues, or alternatively games can be schedule a club home venues. Draws are automatically generated for all but final rounds, but the draws can be edited allowing teams to be moved to position in a draw, whether the edit will be carried over into the next round or not depends upon when you do the edit, but you can regenerate draws for subsequent rounds automatically taking into account previous edits.
It is envisioned that an organisation running a Waterpolo would have an iCloud account that all their iPads would be configured to connect too, having done that then all the iPads can have access to same database.
