Turn a single sentence into a working app you can share
Type what you need in plain language and Whacka generates the interface, data model and logic, then puts it live in minutes.
Real logins, a synced database, file uploads, push notifications, payments and scheduled reminders come included and working on every app.
Chat, image and voice capabilities are added by asking, and the AI calls your end users make are billed to them rather than to you.
Apps stay private until you press Publish, live on a whacka.app subdomain or your own domain, and every version is saved for instant rollback.
