20M App Store Ratings Gone
The problem started on October 23 and wasn’t resolved until October 29. Over 300 apps from over 200 developers were affected, bringing the total number of App Store ratings to roughly 200 million. All 155 countries that Apple supports were affected. Some of the countries that were affected the most include the United States, China, U.K., Russia, and Australia.
Some apps were hit more than others. Hulu was affected the most and found 95% of its ratings gone. Dropbox and Chase lost 85%. It didn’t matter whether the reviews were positive or negative; all were affected. App Store ratings of three and four stars were hit the hardest with a decrease of 40% and 41%, respectively. Two-star ratings decreased by 36% and 5-star ratings decreased by 35%. Ratings of one star dropped by 30%.
No one knows why this happened, and Apple has yet to comment. Mobile app insights platform Appfigures was the one to spot this. Its blog post says that if you’re a developer and your app was affected, or you have more information to share, tweet @appfigures.
