The app basically allows you to access an immense online database of funny photos that you can view (as long as you're connected to the Internet) and comment on if there is something you want to add to any of the images.
In addition to this, one of the most fun things is that users can upload their own creations and submit them to the mercy of others. So, you can create a funny picture, send it, and see if the rest of the app's users like it.
If that weren't enough, thanks to the search function you can find jokes and funny pictures with specific people or things.
iFunny :) is a very, very fun app that is ideal for killing time in those moments when you only have a few minutes of downtime before doing something important.
