I also have this app on my Android phone. I liked it enough to search for an iPad version. You can search by country, frequency, or search by genre/keyword. There are very small, unobtrusive ads which disappear when you scroll up to see search results. Built in, there’s an off button that shuts off the music and closes the app. You can also save favorite stations by pressing a star symbol and retrieve them easily. Thank You for a well-functioning & entertaining app!
