I'm thinking of creating a task management and day planning app, basically a combination of Todoist and Structured. I like Todoist's organization of tasks with projects and labels and priorities, and its due dates and reminders are useful. I also like Structured's time blocking because it actually lets you plan your day and what you will do when, and it lets you track how much time you spend doing things so you can be more aware and plan better for the future. However, Structured is only accessible on iOS, Todoist is Electron on desktop so its not ideal and it has had regressions in the past, and using both together is difficult because you have to manually sync tasks or have AI do it over MCP. So I want to create an app that supports both tasks and blocks; tasks can be organized with projects (including nested projects) and labels and have due dates, while blocks are created as time slots, to which tasks can be assigned. There would be different block types: work blocks that tasks can be assigned to, empty blocks like breaks that tasks cannot be assigned to but that can be moved, and events like meetings which cannot move or accept tasks. It would be easy to shorten or lengthen a block, if you end early or late, in which case the app will offer proposals for adjusting your later schedule that you can accept or change. Suggestions for filling blocks would also be supported, based on task priorities and time estimates assigned to them. I'm going to do this for myself in any case, but would anyone else actually use this? Both mobile and desktop would use the native UI frameworks rather than things like Electron or Flutter, and I want to create a CLI and a BTSpeak UI too. It would probably be a lot harder to make it visually appealing so I would mainly focus on the blind and on making it work the best with screen readers. And syncing would be between devices, not requiring a central server to host the data.
