Overall, Things has no parallel in the productivity GTD space, because there's no other with a better balance of rich features and ease of use. It's an app that feels like it was created by designers/UX specialists first, and engineers second, whereas a tool like OmniFocus with some nice design to boot, nonetheless comes across as primarily the product of engineers.

Things is unparalleled in one area: design-empowered usability/simplicity. Productivity tools often compete on feature sets, but Things shows that sticking to a core set of features and evolving their design can yield better results than simply adding more features. While other tools can become a chore to keep up to date, Things is a tool you want to use even after several weeks, because of its simplicity. Of course this doesn't mean it's underpowered or lacking in features. It has most of the important hallmarks of a GTD system, and implements them in a UI that makes them accessible. No more, no less.

Thing's integration with MacOs has been its biggest shortcoming for me. While notifications work well enough, they're not powerful enough to interact with the app in a way that doesn't require you to actually open up the app. For example, the default Reminders app has a notification, which allows you to not only mark it as complete, but more importantly delay the notification, so that it pops right back up after 1hr or the next day. The Things notification on the other hand forces you to switch to the app and configure the delay with several clicks rather than just the one that it should take were the notifications to be more powerful.

Overall I really enjoy using Things. It has simplified my workflow, and makes it easy and efficient to keep track of everything I have going on, without being cumbersome or overly involved and complicated to use. I have tried so many different todo list and task management systems over the years, with most being too simple and not powerful enough to do what I need them to, or overly complicated and bloated with features that I don't need, or workflows that are cumbersome. Things really hits the sweet spot for me with the features and power to keep me on task, without slowing me down or frustrating me.

I love how quick and easy it is to put down the things that I need to do every day. I love that there is an inbox where I can do a mind dump with everything that needs to be done at some point, and then come back later when I have time and sort them into certain days to do them, or defer them for some other time. I love that the there is a quick add feature on my desktop, as well as the quick add feature on my iPhone, so that I can quickly throw new things into the inbox when a random thought pops into my head. I always struggle with forgetting things for good if I don't write them down when they pop into my head, and this essentially solves that issue for me as I can almost always grab my phone when a though comes in and enter it into Things quickly and know that it will be there when I come back to it later. I love the way you can use areas, headers, and projects to efficiently label and organize everything. I have multiple ongoing projects that I am working on in different areas of my life, and this makes it easy to keep them all separate, but still be able to keep track of where things are and what the next thing I need to work on is to keep things moving forward. I love how seamlessly the iPhone app and the desktop app work together. There is no thought involved in it at all. Everything stays in perfect sync no matter if I'm working on my phone or on my computer.

The only real complaints I have about Things is the lack of any real collaboration support. It would be really useful to be able to add people to certain projects or task lists, or to assign people certain tasks in a project, and they be able to see, add, edit, and mark off tasks as they go. Or be able to have a team track along with how projects are going and what their current status is. I see a lot of people also complain about the lack of attachments also. While this isn't something that personally affects my workflow, I can see how it would be useful, and understand why people are frustrated that it isn't supported. I think if they had an add on subscription service to allow attachments and collaboration, it would really make it one of the best programs out there.

I am always trying to stay organize and Things ended up being more work than I had hoped for,

I like the concept as I juggle a number of projects at once and need to stay organized. The search functions are powerful. The design is attractive an smart

At the end of the day I found Things to be cost prohibitive for what it does and I found other options that were better for me.

It's simple, effective, and beautiful. Full integration in Apple eco system.

No file attachments. No web interface. Slow development for new features.
