Pro Cloud sync
Users need to create an account for Things Cloud (the account can be created from any device). Once signed up, cloud sync will be active, and you’ll have to login on all of your devices to complete setup. From that point on, syncing happens in the background. It is invisible and always reliable.

Pro Easy to set up and use
Things 2 works from the moment you start it up. Simply add a task and when you want it done by. You can also add notes to tasks or tag when you need them. Things allows you to quickly and easily start keeping track of your tasks.
Pro Project support
Things 2 has a projects feature that allows you to organize your tasks together. You can select a project you need to get done and Things helps you focus on each task to get it done. You can even group projects together to focus on the most important aspect of your life at the time.

Things is one of the best apps of doing Getting Things Done.

Pro Publish and share notes

Fully functional offline mode.
Pro Omniplatform

Pro Task/calendar syncing (Google Calendar & Outlook)
Any task with a date/time assigned to it will be exported to calendars optionally connected. Completing the task removes it from calendar.
Pro Multi-level tagging (personal/hobbies/bike-rides) to keep organized
Any note can be assigned as many deeply nested tags as desired. The tag hierarchy can be navigated, filtered on tasks or notes.
Pro Backlinking & networked note references
Amplenote supports the same [[]] syntax popular in Roam to create a link to an existing note. Every linked note has a tab with all the references into that note.
Pro Automatically sorted task list
Every task can be marked as "Urgent" or "Important," along with the time it's due. This makes it possible for the software to automatically sort your todo list in a way that makes sense, and save you time of deciding what to work on first every day.
Cons
Con Expensive if you buy apps for Mac, iPhone and iPad (all sold separately)
As at May 2016 if buying all three apps it cost $80! That said there is no annual subscription and I've been using Things for years and have only paid once so far.
Con Poor calendar view
Could be more convenient with calendar interaction. Not an ordinary approach for visual people, if you want to see all the calendar events in the familiar format.
Con No file attachment available
Con No supported time based/location based alarms
Other apps have these abilities, and they are very useful. Especially for a $10 app, it would be great to include these premium features.
Con Not end-to-end encrypted
