アニチェキ is a simple and convenient anime viewing management app that does not require user registration. It allows users to track the viewing status of each anime as "Not Watched," "Watching," or "Watched." The app provides categorized lists by era, enabling quick access to current season anime. Users can record how many episodes of a TV anime they have watched and search for anime titles. Additionally, the app offers a detailed view for each anime, allowing voice actor searches and self-rating from 1 to 100 points.

The app continuously updates data for past works. It is important to note that the app does not support actual anime viewing. While the app is free to use, it displays ads within the interface.
