YOLO is an app that allows you to ask anonymous questions to anyone you know on Snapchat. When it comes to replying, you can publish your own answers so anyone can read through them. Or, alternatively, opt to not respond at all if you don't want to.
In order to use the app, you have to sign up via your Snapchat account. As long as you have Snapchat installed on your Android, all you have to do is tap a button and you automatically access the YOLO interface. Write up any question you want to ask, and change the background color so the question appears. Plus, you can tap on the 'random' button so the app itself asks you random questions.
YOLO is a fun little tool for Snapchat regulars. Now you can ask questions and share answers through this social network easier and faster than ever. Plus, the answers you get will appear directly in your 'stories'.
