With this convenient app you can calculate your bridge score with three or more clicks of the button or quickly compare your score to the opponent's potential score to see whether you should make a sacrifice bid, even if they double your contract.
The score is shown at the top of the screen, followed by the contract you specified. The breakdown of the total score is also shown (trick score, game or part-score bonus, slam bonus, insult bonus, etc.)
A four page document is included where all the scoring rules of bridge are set out - tabulated and also with explanations and examples.
Beginners would find the description of the rules valuable. More advanced players could use the app for those tricky scores, e.g. you are vulnerable, you made many overtricks, the opponents doubled and you redoubled or you went down with lots of tricks, doubled and redoubled.
