That being said, as someone who has been making memes for 6+ years I can tell you hands down no mobile app will ever compare to the power of photoshop, or GIMP for that matter. Even if it was possible for a mobile app to do everything photoshop can do, the small screen size and touch screen interface is a huge issue that can't be solved without plugging a mouse + keyboard into a tablet, at which point, just use a computer.

There is an interesting phenomenon that the younger generation is so enamored with mobile apps and devices that many of them don't realize how certain use cases/work flows simply are always going to be way better on a desktop or a laptop. I would characterize your comment as saying its possible to profit off of the ignorance of a certain subset of today's 15-25 year old's when it comes to this fact.

I know there are so many brilliant people in this generation who are going to be sick nerds one day. But lots of others only interact with computers via their phones and don't even realize how silly they are being by refusing to make memes on a laptop.
