What's the best iOS app for finding detailed cast and crew information while watching movies or TV shows?

IMDb is a comprehensive database application designed for accessing detailed cast and crew information for movies and TV shows. The app excels in this use case due to its vast repository of data, which includes actor profiles with biographies, filmographies, and specific character names for each title. For example, during a viewing session, users can quickly search for an unfamiliar actor to see their other roles or career background. Features like the search functionality, personalized watchlists, and integration with streaming services enhance practicality, allowing users to track films they've seen or plan to watch. Users report that IMDb is highly reliable for cast details, with reviews consistently praising its accuracy and breadth of information. However, some limitations exist, such as occasional app glitches; feedback indicates sporadic issues with watchlist syncing, where saved data might disappear unexpectedly. Despite this, the core functionality for cast and crew lookup remains robust and widely trusted. The interface is intuitive, facilitating quick information retrieval without clutter. For film enthusiasts or casual viewers needing to identify actors or explore credits, IMDb serves as an indispensable tool on iOS devices, balancing depth of data with user-friendly design.
