User reviews

Users appreciate Cat Catch for its ease of use, effective video downloading capabilities from various platforms, and user-friendly interface. It is considered a top choice among online media downloaders. Common issues include inability to download some Bilibili videos, duplicate file downloads, problems with merged video/audio playback quality, errors with large file downloads, and lack of Incognito mode support. Overall, it is well-regarded but would benefit from improvements in these technical areas.
