Hi. Thanks for your comment. Twos is a great approach to having your tasks, calendar, notes, and events in one place. I think it’s all about personal preference and the environment we’re in. Some people might not like the fact it doesn’t have an app for smart watches like Todoist has. 
You can push reminders to your calendar, so they pop up as an alert when you need reminding. I hope you end up enjoying the app/website.
