Ranked in these QuestionsQuestion Ranking
Pro Daily review
At the beginning of every day, a yellow box appears at the top of the Today section, displaying all tasks scheduled for this day. You can investigate them, and then decide which ones you’ll have for that day and which one you’d rather want to delay.
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.
Pro Nested tags
It's very easy filtering tasks that belong to various areas (etc private vs work)
Pro Great for GTD
Things is one of the best apps of doing Getting Things Done.
Pro Customized calendar
The calendar view (when selecting a due date for a task) is a customized, scrollable version of the default iOS calendar view. This makes it look familiar, but also functional for Things 2's requirements.
Pro Allows adding items via email
Pro Allows setting how much effort a task will take
You can set how long a task will take and how much effort will it ask of you on a scale of 1 to 3.
Pro Solid project management
Pro Use start dates
A vital functionality in a GTD app.
Pro Beautiful interface
Clean, intuitive user interaction. The design is very thoughtful. Somehow it makes Things feel clunky, despite obvious similarities of all GTD platforms.
Pro Allows to add postponed tasks
You can postpone a task. It helps not to clutter task lists up until you really need them.
Pro Native support for Areas of Responsibility
Pro Beautiful interface
Clean, intuitive interface — both desktop and mobile. Lots of intelligent design thinking behind this. Somehow makes other GTD apps like Things feel clunky, despite similarities.
Pro Can email focus list
The app can send you the most important items for the day in an email.
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 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 No native desktop applications yet
Currently the only way to access the app on a desktop machine is via a webapp.
Con No way to add sub-projects
Con No way to work with teams
This is a one-person solution, there is absolutely no ability to share projects with others.
Con No bulk (copy/paste) feature
Con Does not integrate with other apps or services
Con No recur upon completion option
If you have a daily recurring task, it will recur every day regardless if it's been completed the prior day.
Con No desktop widget
Con No way to color-code projects
