Hi PabloCLima - Our focus and goal is to provide a robust portfolio for numerous content types across the collaborative work management needs of teams of all disciplines. Microsoft Lists is an information tracking app that enables teams and organizations to manage a process or workflow. While To Do and Planner are purpose-built apps, specifically designed to help individuals and teams manage their work using tasks. Commonly, when a task is completed, it becomes hidden from view. Microsoft Lists, on the other hand, enables users to collect, view, filter, sort, collaborate, and share structured information across status, life cycle, ownership, and more. Lists integrate with the Power Platform to design, build, and extend productivity apps alongside Power Apps (custom forms) and Power Automate (custom flows). Learn more about Microsoft Lists, and learn more about To Do and Planner.
Also, please review the recent Lists GA blog, "Microsoft Lists begins general availability roll out to Microsoft 365" - with a release timing FAQ; here for summary: "The new Microsoft Lists home page and associated eight ready-made templates will begin roll out by end of July 2020, first to Targeted Release customers and then to the broader production environment – inclusive of enterprise, education, and government plans. The Lists app in Microsoft Teams will begin roll out by the end of August 2020. All are expected to be complete in production worldwide by the end of October 2020." And this is not region specific - we increase the percentage of tenant availability as we progress simultaneously worldwide.
Thanks, Mark Kashman (Lists PMM)
