Ranked in these QuestionsQuestion Ranking
Pro Support for Apple Watch
Pro Offers detailed options
Adding a task can be as simple or complicated as you like. A to-do list entry can simply consist of its title, or you can also add notes, recurrence, set a due date, tag a location, schedule an alarm, priority (low, medium, high, starred) and tack on a URL or photo. You can even make an audio recording with voice notes. And each list is sortable by a number of criteria, including priority and due date.
2Do conforms to your workflow instead of forcing you to conforming into some preset workflow. It helps to accommodate your workflow through a series of features including tags, batch editing, configurable presets, and the ability to quickly add tasks at any time.
Pro Updates have remained free since beginning of time
Unlike many other apps that will release a new paid version when major features get launched, 2Do doesn't resort to that.
Pro Advanced search
Find old tasks or organize smart lists based on complex search terms (for example, “tasks to do at home between 6 pm and 11 pm”).
Pro Get Things Done-style inbox
You can use 2Do according to the Get Things Done methodology – or not.
Pro Variety of organization methods
Use a combination of tasks, projects and checklists.
Pro Optionally sync with iCal or Outlook
The app can optionally sync with iCal or Outlook with free helper software available from the 2Do Website.
Pro Automated Next Steps
Next steps have a separate view. Tasks can be updated sequentially or parallel.
Pro Projects and Tasks can be endlessly nested
You can nest multiple projects with tasks, there is no limit.
Pro Has an offline mode
No permanent internet connection needed.
Pro Specifically designed for GTD
Web-based, progressive-web-app (PWA).
Pro Realtime synch
Data instantly updates on all devices.
Pro Clean design
Lots of space helps focus on the tasks.
Con Decreased cross-platform support, new versions only for iOS
For those that use multiple mobile platforms, support for the Android version has been dropped meaning there is no longer parity between the apps on iOS and Android.
Con No attachment capability
2Do will create a link to a file, but will not store the actual file as an attachment.
Con Beta interface is confusing for first-timers
The interface is very opinionated (this is a good thing). But it is not obvious how to map user's own GTD variant onto the one the author has in mind. Maybe after it is in production, there will be better on-boarding.
