RadioLand

Enter RadioLand, the culmination of a research endeavor to reliably predict the signal strengths of FM stations given any spot in North America or the Caribbean. Using either your device's location or a searched for location, with adjustable thresholds, RadioLand queries a database containing every FM radio station in the U.S., Canada, Mexico, the Caribbean, and Bermuda. Using Longley-Rice propagation data, RadioLand returns a signal strength value that factors in terrain and other obstacles.

View the listings either in list form, or on a map view with color-coded markers representing signal strengths. Each station has a listed programming format and slogan. Filter list or map views by format, slogan, call letters, or frequency.

Coverage maps for select U.S. stations showing their Longley-Rice projections are also available in the app. View a terrain profile to show elevation impediments between your searched for location and the origin radio station.

Customizable searches by frequency, call letters, or additional parameters from a location.

You won't find a more feature-packed app for FM radio listings on Android or iOS, period.
