A half-decade later, Google finally made a decent to-do list app.
For years, Google's to-do list app Tasks was poorly integrated and underdeveloped. Recently, Google has combined all their reminder products into a single Google Tasks app that is accessible across Google products. While still lacking some advanced features, Google Tasks' simplicity and integration make it easy to add tasks and see reminders across Gmail, Calendar and Assistant. The author enjoys being able to say "What are my tasks today?" to Assistant and have tasks show up in Calendar. However, the author notes that Tasks still does not integrate well with multiple Google accounts.
