This app and Todoist Web are nice products, but they do have their issues: 1. It's hard to know what to expect from Todoist in the future. Updates and fixes take a very long time, and there is no public roadmap or issue/request voting system. 2. Todoist promotes itself as great for the GTD method, but it lacks core concepts like Next Actions, Waiting For, and Reviews. 3. The app refuses to start if you don't like Google Services (GSF) on your phone.
