How can I find the price of an app in the App Store before downloading?

When I find an app I get no price set for it. How can I find the price before downloading?

If the button says "Get", the app is free to download. It may, however, have in-app purchases. It usually says so right next to the button.

An app that has a price will say so.

the app store shows the price, if there is no price, then it‘s free

if it’s free, it might have in-app-purchases, which you can see the prices for only in the description, or somewhere in the app (after free download)
