ニコ生コメントビュアー (Nico Nama Comment Viewer) is an unofficial viewer for Niconico Live comments. This Android application allows users to view comments on Niconico Live broadcasts. It should be noted that this app does not provide access to the actual broadcasts, making it primarily useful for broadcasters.

While the name suggests that it is specifically for Niconico Live, the app also offers basic support for displaying comments from Periscope. However, it is important to mention that not all Periscope broadcasts allow comment viewing.

With its simple and accessible interface, Nico Nama Comment Viewer provides a convenient way for broadcasters to keep track of comments during their live broadcasts. It is a free app, available for Android devices.
