On October 28, 2026, Meta quietly introduced an AI pet diary app named Waddle World, described as a 16-bit pixel-art virtual pet experience in the style of a tamagotchi.
According to its official descriptions on the Apple App Store and Google Play, Waddle World is not a traditional game but rather a “daily diary disguised as a pet.” Users primarily communicate with their virtual pets through voice; the pets generate real-time doodles to illustrate the conversation, while also supporting “cozy mini-games” like stacking groceries and playing word puzzles.
The Play Store page describes it as “a listening little friend” and “a cozy world just for you,” emphasizing a sense of companionship and low-pressure interaction. The app was developed and released by Meta, with the first report appearing on The Verge on 2026-10-28T11:27:30.000Z (Asia/Singapore time zone).
