"らくらじ" is a free app for Android that allows users to listen to and record internet radio. With its simple and straightforward operation, users can easily enjoy radio on their smartphones.

Some of the main features of "らくらじ" include the ability to listen to and record radio broadcasts. Users can also make recording reservations for upcoming programs and record shows they may have missed, including radiko time-free compatible programs, Rajiru Rajiru missed listening service, and NHK Gogaku. The app also offers a radiko time-free recording reservation function to prevent missed recordings of time-free programs. Additionally, users can easily access their favorite radio stations by registering them as "My Radio".

It's important to note that the app requires a minimum Android version of 7.0 and the area judgment is based on the network used, not GPS information. While the app does not guarantee recording, it provides a convenient way to enjoy internet radio on the go.
