Comics apps are mobile or web-based applications that provide users with access to a wide variety of comics, including both classic and modern titles. These apps can offer features such as a user-friendly interface, the ability to purchase or subscribe to comics, and the ability to save and organise comics for offline reading. Some comics apps also include additional features such as the ability to read comics in various languages and the ability to sync reading progress across multiple devices. Some apps have a limited number of comics for free, but most have a library of comics available for purchase or subscription. Examples of popular comics apps include Marvel, Comixology, and DC Universe.
