If you're going to be supporting app development on Android (and you should), you might as well pay for the best content you can. That's what the Google Play App Roundup is all about. This is where you can come every week to find out what's new and cool on Android. Just follow the links to the Play Store.
The photo filter app Prisma has been spectacularly popular on iOS for a couple months, and now it has arrived on Android. This app is completely free and has no ads. I'm not sure how the company plans to make money, but it's already tearing up the charts in the Play Store. It's not the first app to apply filters to your images, but it goes about it in a very unusual way with the power of AI.
Prisma's interface is pretty limited. When you open it, you'll be able to snap a photo from the app, or import one you've already taken. Photos taken in the app are just 1080x1080 pixels, and even when you import a photo is will have you crop it down to a square. The next step is where all the magic happens.
Prisma has more than two dozen filters , but they aren't filters like you'd see in Instagram or Lightroom. Prisma uses server-based processing to deconstruct your photo and rebuild it with a completely different style. The result is a complete metamorphosis of your photo that looks much more complete than simply overlaying things on top of it.
The AI that Prisma uses to do this processing needs a lot more power than your phone has, so all the hard work is done on Prisma's servers. That means you will need an internet connection to use the app. Additionally, processing photos takes a pretty long time. The images captured by Prisma are much smaller than the ones that come from your camera, so those can usually be passed through a new filter in 15 seconds or so. A photo you import might take as long as 30-45 seconds to come back. You can switch between filters you've already tried on an image without waiting, though.
When the edit is ready, you can swipe left and right to change the blending of the new version with the unaltered one. This happens locally on the device, so you won't have to wait for the servers again. From there, you can save the photo or share it directly via the system share menu. Although, this seems a little buggy with some apps. The app's servers are also occasionally overloaded, meaning you'll have to wait a few minutes to try another filter. Still, it's pretty fun to play around with.
