I was pretty sure I knew what it was in 10 seconds, but they didn't tell me, so I had to guess. My guess was slightly off - I thought this was for making websites. It's better they tell me what their thing does rather than making me guess, even if it's an easy guess.

Agree 100%. I had the same thought process and assumed it was a tool for websites until I noticed the Objective-C syntax in the code screenshots.
