Need to keep track or just get things done on the go?, Things (and its desktop app) may just be the app you've been looking for.
Cultured Code appeared on the productivity applications map late last year by launching Things as a free preview or open Alpha for Mac (recently reviewed here on Bright Hub). Of course in a very short time, the early adopters started asking about an iPhone version and being an obliging sort of company, they delivered.
Things ($9.99) for iPhone and iPod touch does not quite have all the features of it's bigger brother but does show much promise.
The purpose of Things is help you get things done and whilst it is very applicable to the Getting Things Done method it is not completely constrained by it. It features all the required areas: Inbox (where you add items for review and categorization later), Today (actions to do today), Next (the next actions on your list), Scheduled (any actions that are scheduled to be done on a certain day), Someday (blue sky ideas or items you would like to do someday in the future), Projects (projects being groups of actions relating to a single outcome) and a Logbook (all done actions end up in here).
Firstly Things has implemented the iPhone interface pretty well, simple one touch navigation gets you to your lists quickly, swiping up and down scans the list. Entering new tasks has been simplified with the 1.2 version and is now done on one screen rather than two.
You can sync with the desktop version of Things very easily as long as your Mac and your iPhone are on the same wireless network, just make sure you have Things running on the Mac and start it up on the iPhone. The two apps should sync almost straight away. So far this has proven to be a reliable and quick method. The nice thing is you can enter actions on the go dropping them in the Inbox, categorize them on your desktop and have it all synced in minutes at a later time.
Every day Things will automatically log actions that you have marked as done (this can be set as a preference). All done actions remain in your Log giving you history of what you did get done.
Projects: These are great, instead of having all of your actions just floating in Today, Next or the Inbox, you can group them in Projects and and track them until the whole job is done.
Today: Normally with GTD, you have your Projects and singleton actions and only attempt to do the next action to progress your Project. Things brings the concept of Today to the Next actions list. Next contains all of the next actions you have in your system so each day you review this list and mark the few that you can do today and for the rest of the day you pretty much only deal with that one list.
