In addition to serving as a field guide, Monarch SOS also offers valuable insights into the threats faced by monarch butterflies and provides suggestions on how individuals can contribute to their conservation efforts. The app keeps users updated with the latest information on monarch conservation and migration news through its "What's New?" section, which is updated every time the app is opened.
