Google Play will soon warn users when apps have ads
Although the ad-supported label will be new to most games and apps it’s already active as part of the Play Store’s “designed for families” section. Google Play announced the families program in April, but it didn’t roll out until June.
By January 11, developers must declare whether or not their apps contain ads. Anyone who fails to properly declare whether their apps have ads could be suspended from the store.
As you can see in the image here, the ad-supported label appears at the same spot you see other notes such as whether an app has in-app purchases.
The impact on you at home: It’s not clear exactly when users will see the new app label. Developers must make the ad-supported declaration by January 11, but that doesn’t mean that’s when it will show up publicly. When it does show up it will be an added bonus for users if they’re wondering whether or not they can expect ads as part of a free app.
