Welcome back to This Week in Apps, the weekly TechCrunch series that recaps the latest in mobile OS news, mobile applications and the overall app economy.

Global app spending reached $65 billion in the first half of 2022, up only slightly from the $64.4 billion during the same period in 2021, as hypergrowth fueled by the pandemic has slowed down. But overall, the app economy is continuing to grow, having produced a record number of downloads and consumer spending across both the iOS and Google Play stores combined in 2021, according to the latest year-end reports. Global spending across iOS and Google Play last year was $133 billion, and consumers downloaded 143.6 billion apps.

This Week in Apps offers a way to keep up with this fast-moving industry in one place with the latest from the world of apps, including news, updates, startup fundings, mergers and acquisitions, and much more.

TikTok is getting a rating system

Some TikToks are too racy or mature for younger teens -- a problem TikTok aims to address with the upcoming launch of a new content ratings system. The "Content Levels" system, as it will be called, is meant to provide a means of classifying content on the video app -- similar to how movies, TV shows and video games today feature age ratings.

TikTok acknowledged some content on its app may contain “mature or complex themes that may reflect personal experiences or real-world events that are intended for older audiences.” It will work to assign these sorts of videos a "maturity score" that will block them from being viewed by younger users. Not all videos will be rated, however. The goal will be to rate videos that get flagged for review and those that are gaining virality. Initially, the system will focus on preventing inappropriate content from reaching users ages 13 to 17, TikTok says, but will become a broader system over time.
