Des Traynor, co-founder of Intercom, argues that humanity has reached peak to-do list apps and is overwhelmed by the numerous options available, making it difficult to find a suitable one. He suggests that users consider their task management preferences, such as grouping tasks in a certain way or preferring minimalist apps with features, when choosing a to-do app. Various categories of to-do list apps are mentioned, including Grocery List apps, Getting Things Done (GTD) apps, Kanban Board apps, and Plain Text and note-taking apps. Ultimately, the key to finding a successful to-do method is to choose one that users will actually use.
