BridgeScorer is an app for scoring whilst playing the Duplicate Bridge card game.
It can score either at-the-table, or after the event.

BridgeScorer can score at-the-table. Each table enters scores simultaneously as the boards are played.
Only one instance of the app is required, but you’ll need (at least) a phone for every table.
If preferred, each pair can have their own phone (which they take with them as they move round the tables), and submit scores when they’re sitting north-south.

The phones communicate over WiFi.
Only the phone running the app needs to be an Android device (phone or tablet), the others can be any feature phone or tablet with a Web-browser, even an iPhone.

BridgeScorer can also score a complete duplicate bridge session (from the travellers) producing results as web-pages for easy upload or e-mail.

Rubber and Chicago bridge can also be scored.

No computer (Windows, Mac or any other) is required.

Wakelock.
When running BridgeScorer “at-the-table” with connected client devices, BridgeScorerService needs to keep running even if the phone is asleep to respond to requests from those clients.
