Welcome to VeriDie, the most useless Android app ever! The only thing it knows how to do, is throwing dices (in other words, generating random numbers), peer to peer via bluetooth. In theory, it could be used by people who play board games, tabletop games etc. In practice, it was just fun to implement the peer to peer communication and try out C++20 coroutines :)
Multiple Android devices connect to each other via bluetooth, automatically negotiate who's going to generate results (like floor control but decentralized, without a server), then share with each other every request made by users and result generated by the negotiated generator. At any point in time only one participant is generating dice cast results. That generator is re-negotiated after every 10th dice cast.
The app seems to work allright, but the GUI is very basic.
