@khaytsus Hello and Welcome to the Forum and Thank You for Using Flowx. if you tap the 3 dots top right then tap edit place you can choose the numbers of days up to 16 depending on your subscription. you can compare graphs by double tapping the graph.
You can save the same place as different places and edit the number of days to show.
I do this also for my most used places, one with 3days for better zoom, one for 10 days for longer forecast.
And saved them as. Home3d and Home10d
