Existing systems

App Store (iOS/iPadOS)

Since iOS 26, Apple's rating system for the App Store has followed the following rubric:

4+: Contains no objectionable material. Apps specifically aimed at children can be placed into one of three subcategories: ages 5 and under, 6–8 and 9–11.
9+: May contain content unsuitable for children under the age of 9.
13+: May contain content unsuitable for children under the age of 13. Replaces the 12+ rating.
16+: May contain content unsuitable for children under the age of 16. Replaces the 17+ rating.
18+: May contain content unsuitable for children under the age of 18. Replaces the 17+ rating.

Apps rated 17+ were prohibited from purchase by younger users.

Google Play

Up until March 17, 2015 Google Play used the following rubric:

Everyone
Low maturity
Medium maturity
High maturity

Google now uses the International Age Rating Coalition in most countries not represented by a rating authority, whilst countries or regions with a superimposed video game rating authority continues applying their own ratings where applicable.
This includes Americas, where ESRB is imposed, Brazil with ClassInd, Europe and Israel with PEGI, Australia with ACB and South Korea with GRAC. However, a new Google Play Rating system is used exclusively in Russia and for non-gaming apps in South Korea.
These ratings include:

In Australia, IARC applies its own ratings for non-gaming apps.
