Would You Rather 18 is a free iPhone app developed by Marmelapp that allows users to play the famous "Would You Rather" game as a group. With this app, you and your friends can gather around and take turns answering some of the toughest dilemmas you'll ever face. The game involves voting at the same time, with those in the minority losing 1 point and having to drink 2 sips as a penalty. It can also be played as a drinking game.

This app is perfect for parties or any social gathering, and it's a great way to break the ice and get everyone involved. The app is easy to use, and the questions are sure to spark some interesting conversations. However, it's important to note that there is a subscription option available that provides access to premium content, including unlimited game modes and no ads. The subscription costs $4.99 USD weekly or $13.99 USD monthly and will be charged to your iTunes account upon confirmation of purchase.
