Building an appointment scheduling app like Zocdoc without coding can be achieved using no-code tools like Bubble. The process involves registering a free account, completing introductory lessons, and choosing to start by wireframing or building database fields. A workflow editor is used to create a new thing (e.g., doctor profile) and add data fields to power the application. Key features include creating a search navigation, displaying dynamic lists of doctors, scheduling appointments, and viewing doctor profiles. The app can be customized and extended using templates, plugins, and the community forum for support. With paid plans starting from $25/month, building an MVP like Zocdoc without coding is a cost-effective option.
