Figure is an app I found while I was browsing through the App Store on my Iphone. At that time, this app was the Free App of the Week, a paid app that the app store recommends and makes it free for a week. At first, when I was looking at the cover, I didn't know what the app was about but since it was a free app , I decided to download it. This is an app where you can feel like a DJ. You make songs by doing your own drum, bass, and lead synths. There are tons of types of sounds you can choose from to make your music. You can even choose the key and beat of your song. With this app, you can make your own electronic music only by sliding your fingers across your phone or tablet screen. It might cost a dollar right now, but if you are interested in the making of techno music, you should try this app to see the concept of how the famous dj's around the world do their work.
