I admit it. I love emojis. From it's release on the convos, emojis instantly became a classic. Since my first app in 2014, I have always wanted to use the emojis in some different way for an app.
One day, I saw an old source code of a trivia game that none want it. It cost 30$ and the seller was really happy to get ride of it. This is how i started using emojis in the AppStore.
