What's the best iOS app for road trip planning with reliable weather updates along my route?

First Alert Weather is particularly well-suited for road trip planning due to its dependable forecasting and route-specific weather information. The app's hourly updates allow travelers to time their stops around weather conditions, while the detailed radar maps help visualize storm systems along planned routes. Users appreciate that the app rarely experiences technical glitches compared to other weather applications, providing consistent performance during long journeys. The integration with local news weather teams adds credibility to forecasts, though some users note the notification system can be overly aggressive during minor weather events. For RV travelers and road trippers, features like precipitation timing, wind direction indicators, and temperature trends make it easier to plan driving segments and overnight stops. The app's reliability stems from its connection to professional meteorologists rather than automated forecasting systems alone.
