The ratings include the following:
- E for everyone - 6 years old and older
- E 10+ - 10 years old and older
- T 13+ - Teens
- M 17+ - Mature audiences
- A 18+ - Adults only
Smartphone and tablet apps first appeared around 2005. The companies that have created the apps have also assigned the rating. In the future, apps creators submit the app to the Entertainment Software Ratings Board (ESRB) and the Board will assign a rating. There is an appeal process for ratings that app creators don't agree with the ESRB.
