First and most important, the only source for weather I trust. User friendly, no glitches, slow loading pages or difficulty finding what I need. the app has so much info at your fingertips! from your favorite golf course and local beaches to the tropics, Severe weather, alerts, health warnings ( allergies, air quality, etc.) even astrology! the Islandwide team and developers knocked it out of the park! 💫

Definitely digging the overall feel and aesthetic of the app design. For a fresh release the devs absolutely nailed it! Been an AccuWeather user for years, however will lean more heavily on this for the local forecast going forward. Looking forward to where they take the app next!
