FaceApp is a mobile photo-editing application which uses neural networks to apply various effect to uploaded photos, making subjects appear older, younger, smiling or a different gender.
Precursor: In Twenty Years
On March 31st, 2008, the web application In20Years was launched, which takes user-submitted photographs and applies a filter to make the subject look significantly older.
In January 2017, FaceApp was released by the Russian app developer Wireless Lab on the iTunes app store. In mid-February, an Android version of the app was released on Google Play, where it received over one million downloads and 47,000 ratings over the next several months.
On August 9th, 2017, the application was updated with new Asian, Black, Caucasian and Indian race filters.
That day, The Verge published an article about the new filters, which included a statement from FaceApp CEO Yaraslav Goncharov, who claimed the race filters were not using biased or prejudice:
"The ethnicity change filters have been designed to be equal in all aspects. They don’t have any positive or negative connotations associated with them. They are even represented by the same icon. In addition to that, the list of those filters is shuffled for every photo, so each user sees them in a different order."
On April 18th, the gaming news blog GamesRadar posted several pictures of various video game characters edited by FaceApp to appear as if they were smiling. On April 22nd, Redditor J_Deedubze_W posted a set of FaceApp edits using a picture of the character Foster Addison from Mass Effect: Andromeda (shown below). Within 48 hours, the post gained over 1,000 (93% upvoted) and 65 comments on /r/masseffect.
