In Apple’s efforts to clean up the App Store, Apple will no longer be allowing submissions of apps with the word “free” or other such terminology related to price in the title.
If a developer tries to submit an application for review, they are presented with an error message saying that they cannot include pricing in the title
Below is the full error message
Your app’s name, icons, screenshots, or previews to be displayed on the App Store include references to your app’s price, which is not considered a part of these metadata items.
Please remove any references to your app’s price from your app’s name, including any references to your app being free or discounted. If you would like to advertise changes to your app’s price, it would be appropriate to include this information in the app description. Changes to your app’s price can be made in the Pricing and Availability section of iTunes Connect.
