Tasks, lists, subtasks, repeats and reminders live right in BrightMind and show up on Home, in your briefing and in the @ picker like everything else. It is already a better fit than Google Tasks. If you use Todoist or TickTick, stay with it for now, that is still the better experience.
This is the start of a task manager built for ADHD brains, with BrightMind doing the remembering, the nudging and the breaking down for you. Every task with a time gets a reminder that survives rescheduling, and tapping it lands you on the task.
