- Share straight in. Hit Share on a video anywhere on your phone and pick Zestimer — it lands as a workout. Copying the link and pasting it still works too. - TikTok now works the way YouTube does. Share one in or paste it, and it becomes a timed workout with the creator credited. - One place to build. The builder and AI Coach are the same screen now — describe the change in a sentence and watch it land, instead of hopping between an editor and a chat. - A new look throughout: every icon in the app is drawn rather than borrowed, and the launch screen has art of its own.
