Prisma has become one of the most popular Android and iOS apps out there. The AI-driven photo manipulating app allows you to quickly and effortlessly turn a photo into a work of art and can produce some amazing results. The only real drawback to the app, however, has been that in order for you to use it, you had to be online. With the latest update to the app, which is rolling out to the Google Play Store now, that changes. You can now use the app offline to do your art creation and even better, you only really need to be online when you are downloading Prisma styles.
