Just tell Dudu. Dudu is a little helper that makes things for you. Ask for a game, a small app or a video and it's ready in a couple of minutes — or hand it an errand and let it take care of it. SAY IT. DUDU MAKES IT. "Make a match-three with my piglets in costumes." A few minutes later it's yours to play and share. Games, little tools, videos and cards, each from a single sentence. LOVE IT? MAKE YOUR OWN. Everything in Discover is one tap from your own version: same game, your rules — your pets, your jokes, your friends' names. SOMETHING NEW, EVERY DAY. Discover is full of games, little apps and videos made by Dudu and by people like you. Swipe, tap Play — nothing to install. Follow the people whose work you like. DUDU KEEPS GOING WHILE YOU'RE AWAY. Reminders, replies, drafts and the small things in between. Dudu works on them in the background and lets you know when something needs you — on your widgets, lock screen and Apple Watch. MADE SOMETHING? WE'LL GET IT SEEN. One tap puts your work in Discover. Dudu writes the posts for everywhere else and shows you who came to play. Reach the goals in My posts and apply to the Creator Program. MEMBERSHIP Dudu is free to try. A monthly membership gives you more to make each week. It renews automatically until you cancel; manage or cancel it anytime in your Apple Account settings. Terms of Use: https://ybuild.ai/terms Privacy Policy: https://ybuild.ai/privacy
