Muy útil

Es una gran aplicación para leer libros. Yo leo muchísimo y con 24symbols tengo acceso a una gran oferta de libros (aprecio especialmente los de la editorial anagrama pero también están Herder, Siruela, Salamandra y con un catálogo espectacular). Me funciona perfectamente.

muy incómoda

para ser la forma de leer los libros de 24s, es tremendamente incómoda de usar. es lenta, no guarda la página por la que estás leyendo cuando cambias de dispositivo y no soporta la vista apaisada, lo que hace difícil la lectura en el ipad. y para ser de pago la opción premium, deja muchísimo que desear. espero que mejore pronto para que realmente sea un placer la lectura

Buena opción

Me parece una buena idea para leer en cualquier momento. El catálogo no es muy extenso aunque hay libros para leer gratis que están muy bien. El problema de que se quede colgada la aplicación a mí no me pasa. Un problema que veo es que no se sabe el número total de páginas de los libros. (O yo no sé dónde verlo)

Llevo bastante tiempo con la app. Me gusta mucho el formato y la variedad de libros. Lo malo es que con cada actualización de iOS tardan mucho en adecuarla y se perciben errores desesperantes. De no ser por esto último la calificaría como excelente.

Algunas veces se bloquea

En términos generales es muy buena, tienen que arreglar el tema de los bloqueos y queda perfecta

Launch Services
The AV Foundation framework provides an Objective-C interface for managing and playing audio-visual media in iOS and OS X applications.
Core Foundation Framework
Core Foundation is a framework that provides fundamental software services useful to application services, application environments, and to applications themselves. Core Foundation also provides abstractions for common data types, facilitates internationalization with Unicode string storage, and offers a suite of utilities such as plug-in support, XML property lists, URL resource access, and preferences.
Core Graphics
The Core Graphics framework is based on the Quartz advanced drawing engine. It provides low-level, lightweight 2D rendering with unmatched output fidelity. You use this framework to handle path-based drawing, transformations, color management, offscreen rendering, patterns, gradients and shadings, image data management, image creation, and image masking, as well as PDF document creation, display, and parsing.

System Configuration F...
This collection of documents describes the programming interfaces of the System Configuration framework. The System Configuration framework provides functions that determine the reachability of target hosts in both a synchronous and an asynchronous manner. It also provides error detection facilities.
Core Location Framework
The Core Location framework lets you determine the current location or heading associated with a device. The framework uses the available hardware to determine the user’s position and heading. You use the classes and protocols in this framework to configure and schedule the delivery of location and heading events. You can also use it to define geographic regions and monitor when the user crosses the boundaries of those regions. In iOS, you can also define a region around a Bluetooth beacon.
The UIKit framework (UIKit.framework) provides the crucial infrastructure needed to construct and manage iOS apps. This framework provides the window and view architecture needed to manage an app’s user interface, the event handling infrastructure needed to respond to user input, and the app model needed to drive the main run loop and interact with the system.
Quartz Core Framework
This collection of documents provides the API reference for the Quartz Core framework, which supports image processing and video image manipulation.
