Yes, it’s a forecast app, but it’s more interested in showing you how weather systems move than simply telling you whether it’s going to rain.
The app gives you a map and then you can choose whether to track precipitation, cloud, wind speed, temperature, pressure or wave height. Then zoom in or out with a pinch and swipe slowly to see how these conditions are predicted to change over a period of hours or days, by watching for example clouds or storms move across the map.
You can add arrows to give you a clearer picture of the direction weather systems are moving in, key details such as the temperature are shown at all times, and you can customize the units of measurement.
Flowx probably won’t replace your normal forecast app, in fact the app description even suggests you use Flowx alongside a more conventional weather app, but if you want deeper insight into weather patterns it’s a fascinating addition to your app arsenal.
And if you get really into it an IAP of $1.99/£1.99 per year or $4.99/£4.99 as a one-off will remove adverts, give you 10 days of data instead of 7 and ensure you get future features.
