This app us built in go (server) and flutter (app ios and android), it used grpc for apis, and remote container extension for development of the server (using docker)

The app is not yet puclished, and i think im not going to add ads inside, only donations, so it will be free, i think i will publish it only on play store due app store restrictions for chatroulette apps
