Pros
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.

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

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 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.
