Support us

Support us in our mission: keeping bridge alive.

We build BidTrainer out of love for the game and have funded it entirely ourselves so far. Hosting, maintenance and further development cost money, and grow with the number of players. Something small already helps.

Where your contribution goes

Servers and storage for the app and all boards
Further development of the bidding engine and modules
Maintenance, so the app keeps working

Build with us

Become a beta tester!

Digitising bridge is hard: every auction, every exception and every system has to be right. That is why players test new features first, before everyone gets them. You get new features first and tell us what could be better.

Do you need bridge knowledge for that? No. Beginners spot what is unclear, experienced players spot what is wrong at the table. We need both.

Players, clubs and organisations who contribute and want to be visible. There is no one here yet, so the first spot is yours. Their sign grows with how long they have been helping us build: ♣ ♦ ♥ ♠. We never show amounts.
