Bubble is a no-code platform that allows users to build fully customizable web applications and workflows, ranging from simple prototypes to complex marketplaces, SaaS products, and more. The 2Doozi app was built using Bubble by its founder, Malcolm Lewis, who has over 20 years of experience as a software marketing executive and started his career as a developer at Oracle. The app is an entertainment to-do list that enables users to manage their personal lists of TV shows, movies, books, places, and more, with features such as saving items for later and seeing what other people are doing. Malcolm chose Bubble due to its simple features and helpful plugins, and has been pleased with the app's development process, with future plans including minor tweaks and potentially incorporating taste-based recommendations and identifying cohorts of users with similar tastes.
