Keep deals in collections

Sort deals into collections: tournaments, interesting auctions, training material. Any collection can be downloaded as a PBN file or used as the source of deals for an online match.

ChallengesAlpha

Play a set of deals with bots and compare your score with friends who played from the same seat. Note: this module is in alpha while a better bot is being built. If you want to play anyway, turn challenges on in settings.

Always free

The app will always be free, as long as the size of your data and the tools you use do not run up significant cloud costs.

  • The number of saved deals has a limit, but a generous one.
  • Double-dummy analysis of single deals will stay free. Fast cloud simulations and agent features may be paid in the future.
  • I already pay about 50 PLN a month for the cloud. When more traffic raises the costs, I will keep it running on donations, and will probably trim the free storage somewhat.
  • The first visit often takes about 5 seconds to load — with no traffic the service sleeps. When traffic grows, I will turn off scale-to-zero.
