You probably guessed it from the title, but yes! It is Tik Tok. Tik Tok is an iOS and Android social media video app for creating and sharing short lip-sync, comedy, and talent videos. To be honest, I didn't really pay much attention to it, until I realized how many people actually use it - from my younger sister and her middle school friends, to school teachers, to social media influencers, even to some students clubs and organizations right here at NC State.

The app was launched in 2017 by ByteDance, for markets outside of China. In 2018, it became the most downloaded app in the US and has been downloaded more than 800 million times worldwide, according to data from the mobile research firm Sensor Tower.

In short...

"The Tik Tok mobile app allows users to create a short video of themselves which often feature music in the background, can be sped up, slowed down or edited with a filter. Users can also choose background music from a wide variety of music genres, edit with a filter and record a 15-second video with speed adjustments before uploading it to share with others on Tik Tok or other social platforms. They can also film short lip-sync videos to popular songs."

I wondered how it worked, so I gave in and downloaded it. To my surprise, I was actually quite impressed with the framework of the app and admired how the app developers crafted something so simple, yet something so unique that it is taking the world by storm.

I noticed that Tik Tok had a good and well-layed out UX/UI design to not only attract new users but also keep existing users. Here are some important components of the UX/UI design that I found really interesting.
