BetterCrewlink is a free mobile application developed by OhMyGuus for the Android platform, which is categorized under Social & Communication. The app requires one PC player with BetterCrewlink for it to work. It is designed to facilitate the communication between the players of the popular online multiplayer game, Among Us.

To use the app, you need to install it on your phone, start it, and then join a lobby with at least one BetterCrewlink PC user. After that, you will need to ask one of the PC users to enable "Mobile host" in the settings. You can then fill in the lobby code, voice server, and your Crewlink name (use a unique name). Once you click connect, you will be directed to the connected players page.
