Free FM radio apps, including iHeartRadio, Radio FM and RadioTunes, typically feature options to sort the available stations by country, to create a list of favorite stations and to share radio stations with friends. Some apps, such as NextRadio, provide an option to contact specific radio stations within the app.
IHeartRadio features an option to personalize the recommendations of radio stations based on the user’s taste in music. It also lets users access their favorite stations from the home screen. Unlike most other FM radio apps, NextRadio utilizes the phone's built-in FM tuner – if it features one – to save battery life by not streaming radio content from the Internet.
