My point was that most apps on the App Store / Google Play (and therefore most of the ones you probably have installed) are heavily consumption-focused -- not that these utilities don't exist.
I'd wager the same is true for personal laptops, though. There are certainly many more 3D games than 3D editors, and many more video players than video editors.
The point is that within these smartphone apps, there are often consumption and production elements. E.g. on Instagram, the app opens to a stream of activity (consumption). You have to tap a button to start to produce something. Compared to the Camera app or Photo Booth on my PC, both which exist to enable me to produce first, Instagram is focused on consumption first. That's what I find odd.
Whatever made you think mobile platforms don't have those tools?
