Weather on the Way is a free weather app developed by Piotr Knapczyk and designed for iPhone users running iOS 13 or newer. The app is designed to help users plan their road trips by providing precise weather forecasts for the entire route. It combines weather and navigation to give users a route forecast at the exact time they will be driving through.

One of the app's standout features is the ability to set waypoints on the way and stop duration, which allows users to plan their trips in detail. The app also provides a timeline that shows the time and place of sunset and sunrise, as well as a general forecast for the day of arrival. Another great feature is the live snow and rain Doppler radar, which provides real-time data on weather conditions.

The app is privacy-focused and does not collect any personal information, including location or chosen driving route. It works in over 70 countries and provides severe weather alerts in the US, Canada, European Union member nations, and Israel. Weather on the Way is a must-have for anyone planning a road trip who wants to be prepared for any weather conditions along the way.
