A Service to Check App Ratings Before Launch

A new way to handle age ratings

From August 12, 2026, Apple lets apps with an official rating from the Game Rating and Administration Committee (게임물관리위원회), Korea’s game-rating authority, enter a rating classification number and redefine their Korea App Store age rating. When submitting the next app version, they can reflect the authority’s rating: All Ages, 12+, 15+, or 19+.

Apps without an official rating cannot simply choose a number. The app operator answers questions about items such as profanity, violence, chat, user-generated posts, advertising, web access, and gambling, and Apple calculates the rating.

The Korean criteria will change again in October 2026. Infrequent profanity and explicit humour, along with infrequent adult or suggestive themes, will become 12+ factors rather than All Ages factors. Even apps currently displayed as All Ages have a reason to review their posts and conversations.

Korean regional ratings appear separately mainly for apps in game or entertainment categories. Apps in any category that contain frequent or intense simulated gambling can also be covered, and may need a rating classification number for distribution in Korea.

Matching the rating number is not the end of the work. If an app handles content for people aged 19 and over, the required identity-verification method depends on whether that content is legally designated as harmful to minors, so it needs separate review.

Bringing one app’s information into one place

Consider the operator of a fan-community app in Seoul with 12 employees. The app is in the entertainment category. Users post writing and short videos, and use one-to-one chat. Some links lead to external pages selling concert tickets and adult products.

When releasing a new version, the product planner reviews the feature list and answers Apple’s questionnaire. A marketer separately creates store copy and screenshots. A developer collects dates of birth at sign-up. An operations manager removes reported posts, but does not separately record which expressions appear or how often.

Under this structure, the same app is described in four different ways. The questionnaire may say profanity is infrequent, while reports accumulate every week. The store description may call it a safe community, while suggestive images appear in popular posts before login. When ownership changes, it can also become difficult to find the basis for earlier answers.

A Korea-launch review tool could ask once for the category, whether chat exists, types of user-generated posts, external web access, frequency of adult themes, age-verification method, and whether the app has a rating classification number. It could compare those inputs with Korean rating criteria and show inconsistencies across the rating questionnaire, sign-up screens, content exposure, and store listing.

Before submitting the app, the operator could handle Korea-specific differences first. For example, if the team expects an All Ages rating but infrequent profanity remains, the tool could flag it as an item affected by the planned October change. If an adult-product link opens before login, it could create a task to reset the access condition.

During operations, reported posts could be recorded under categories such as profanity, suggestive content, violence, and gambling. At the end of each month, the team could use those records to check whether questionnaire answers still match the live service. Whenever app screens change, it could retain before-and-after screens along with the responsible person’s judgment. If reviewers ask questions, the team could immediately retrieve the basis for its answers and the steps to reproduce them.

Human judgment still remains necessary. The same expression can be assessed differently depending on context and frequency of exposure, and a tool cannot determine what identity verification is legally required. Rather than targeting every app as its first customer, the service could focus on small operators launching game or entertainment apps in Korea, where common questions and screens can be gathered quickly.

Approaches already established in other regions

ClassInd, run by Brazil’s Ministry of Justice, operates an age-classification system for games and apps distributed online. Through the International Age Rating Coalition questionnaire, developers can receive a Brazilian rating at no separate cost, while one set of answers can also handle ratings for multiple regions.

In Brazil, this classification connects to app functionality rather than serving only as a label. Apple rates apps that disclose loot boxes as 18+ in Brazil, and since February 24, 2026, has blocked downloads of 18+ apps for users whose adulthood has not been reasonably verified. It is an example of the same feature changing distribution conditions by region.

In Australia, game companies can pay the Australian Classification Board for a formal classification review. The published first-stage application fee is AUD 1,210, the standard processing target is 20 days, and priority processing adds AUD 420 with a target of five days. Discovering this route just before launch can delay the entire schedule.

In June 2026, Apple removed the existing 15+ band in the Australian App Store and moved those apps to 16+. Government classification and a store’s regional display move together, so tracking local rating changes alone could also be a standalone service.

The French social app Yubo applied Yoti’s facial age-estimation feature to all users. Yoti provides age-verification features to app operators and charges through business contracts, but Yubo’s actual contract amount needs verification.

Yoti has said it processed more than 290 million age checks for Yubo. It also said that, in a survey of more than 10,000 users, over 60% reported a better experience; this company-reported figure needs separate verification. The important point is that age verification was used not as a single sign-up screen, but as an operational measure to reduce encounters between users in different age groups.

Four things to build for a Korea launch

1. A Korean age-rating pre-checker

The service would show which Apple questionnaire items need another look and where a Korean rating may change after an operator enters app features. Its users are operators with fewer than 20 employees launching their first game or entertainment app in Korea.

The timing matters because a process now exists for reflecting rating classification numbers, and a Korean criteria change is planned for October 2026. The first screen would ask about the app category, chat, user-generated posts, web access, frequency of profanity and suggestive content, and whether the app has an official rating.

2. A builder for age-based sign-up and access screens

The service would be a screen-building tool that arranges date-of-birth entry, parental consent, adult verification, and restricted-content notices in the required order. Its users are hobby-community operators whose services are used by both minors and adults, but where only some boards or products are available to adults.

When store ratings and actual content-access controls are managed separately, their explanations can easily diverge. The first screen would show a flow of who must verify what before viewing each type of content, while separating legally required identity verification as an item that needs confirmation.

3. A decision log for user-generated content

The service would keep reported posts and videos, their type, frequency of exposure, handling outcome, and decision basis in one place. Its users are domestic community apps where fan videos, anonymous posts, and chats arrive every day, but only one or two people handle moderation full time.

As user-generated content changes, the rating answers submitted at launch can drift away from reality. The first screen would show that month’s report counts for profanity, suggestive content, violence, and gambling, along with unhandled items and changes that require another questionnaire review.

4. A pre-checker for store-listing screens

The service would review app icons, store screenshots, and preview videos for material that may be inappropriate for younger users, then manage replacement tasks. Its users are game companies whose apps are 15+ or 19+ and that use strong combat scenes or adult material directly in promotional screens.

When an app’s internal rating and the material shown in the store are managed separately, their explanations can easily diverge. The first screen would include an area for uploading store screens and a checklist for violence, exposure, weapon targeting, and adult wording.

What to check with one app today

Choose one live Korean game or entertainment app and spend 30 minutes listing its store rating, store screens, age information collected at sign-up, posts visible before login, chat, and external links. If, across at least three of those five areas, the responsible person cannot immediately explain the current setting or find the record behind it, a small paid Korea-launch review tool may be worth testing.

Why this matters where you are

The Korean example shows that an age rating can affect more than a store label: it can conflict with sign-up, content access, user-generated content, and marketing material. Check whether your own market has separate official ratings, platform questionnaires, or age-verification conditions that affect the same screens. The local rules may differ, but a single record of the evidence behind each rating answer can still make changes easier to review.
