[Update] Ken Case comments below, addressing some of the concerns listed here. It looks like a future version of OmniFocus on the Mac will be able to directly update the OmniFocus reminders on the server, removing at least one of my complaints.

Ken Case from The Omni Group has been twittering for awhile about the impending inclusion of alarm reminders for OmniFocus. The task management app's iPhone users have been pestering The Omni Group to implement reminders as push notifications, but OmniFocus refuses to do so. They say that reminders that rely on connectivity are not good enough, and they have instead chosen to implement reminders by exporting due dates and times into iCal. Once the time comes for a reminder, it pops up like a normal iCal appointment reminder.

Well, OmniFocus 1.5.2 for iPhone was released, and now we get to see how this alternative reminder system works. If I had to choose a word to describe this implementation, that word would be "awful." Here's why:

• The Omni Group has taken great pains to point out that you do not need to be using the desktop version of OmniFocus to get use out of the iPhone version. But for users that only have the iPhone version and are not synchronizing it to either MobileMe (which has a yearly fee) or a WebDAV server (complicated for non-techies), they can't use this implementation of reminders. That's right; the way it works is that OmniFocus on the iPhone exports your reminders to your synchronization server, then points iCal on the iPhone to the server to import your reminders. That means that if you enter new due dates in OmniFocus for iPhone but don't happen to have connectivity, you won't get reminders. Wait, I thought it was implemented this way in the first place to guard against a lack of connectivity?

• Your OmniFocus reminders unnecessarily pollute your iPhone calendar with reminders. This is a visual problem when you need to glance at your calendars and see what actual appointments are coming up. On the iPhone you can either look at one specific calendar, or all calendars, so if like me you need to regularly stay on top of more than one calendar, you're forced to look at your OmniFocus reminders as well. Oh, and even when you complete them in OmniFocus and resync, they don't go away in your calendar. [Update] Stephen points out in the comments that this works as expected, and upon further testing I have to agree. Maybe I was being a bit too impatient.
  

• Since your OmniFocus reminders are actually just fake appointments, there is no way to audibly differentiate them from appointment reminders. They sound and look exactly the same. Remember the Milk, for example, uses push notifications on its iPhone app, and you can set the notification sound to a number of different options. That way you know that you're being reminded of a task rather than an appointment.

• Reminders are set based on Due time, rather than Available time, and in terms of flexibility you can set the reminder to be 5 to 60 minutes before the task is due. By the time a task is actually due, isn't it too late to be reminded about it?

• Finally, if you're a user of OmniFocus for the Mac, your reminders are not created on your iPhone until you think to launch OmniFocus on the iPhone and synchronize it. That means that if you work all day in OmniFocus on your Mac (like I do), then drive home and start doing other stuff and don't happen to open OmniFocus on your iPhone, you won't receive any reminders for tasks that you might have set for that night, or until you actually open and sync OmniFocus on your iPhone.

So, what would I rather see? Push notifications, like the many other OmniFocus for iPhone users out there that have been providing their feedback to The Omni Group.

As mentioned, Remember the Milk has implemented push notifications, and the ability to change the notification sound isn't the only trick it has up its sleeve. The Remember the Milk icon on my iPhone's screen shows how many due tasks I have that day, and the number changes almost instantly when I make changes on the web version. To see how many currently available and due tasks I have in OmniFocus, I again have to launch the app and wait for it to synchronize.

While I love OmniFocus and I think The Omni Group does amazing work, this implementation of reminders for the iPhone version of OmniFocus is just full of an amazing amount of fail. It's a hacky workaround that still doesn't ensure that a lack of connectivity won't adversely affect the user's ability to receive reminder notifications. Omni folks, this is just meant to be tough love -- I wouldn't be saying all of this if I didn't truly care about OmniFocus.

Things Touch 1.3.5 has been released along with Things 1.1 and, among a heap of bug fixes and UI improvements, you'll find a new feature for syncing Areas of Responsibility from your Mac to your iPhone (it's not yet possible to create Areas in Things Touch). The feature requires Things 1.1 on the Mac side, which was officially released today, but has actually been available (sans release notes) for about a week (assumedly waiting for Things Touch to make it through App Store approval).

Another new addition (which is more exciting, to me) is full AppleScript support in Things on the Mac. I haven't had a chance to dive into it yet, but it's a topic I discussed with Cultured Code at the last Macworld Expo and I'm excited to see it come to fruition. People using Things in any kind of group setting will appreciate the reconsidered approach to task delegation, as well.

For those who aren't familiar with Things in general, I'll take a quick step back. Things for the Mac has been a staunch competitor in the Mac task-management colosseum. Battling it out with OmniFocus and newer gladiators like The Hit List, it's been recognized by many for its simplicity and elegance. Things is powerful and flexible, while remaining reliable and simple. Things Touch is its iPhone companion, usable on its own or synced with Things Mac.

You may be asking, what's an "Area of Responsibility?" This is one of the features of Things which was hardest for me to grasp. It's not quite a GTD context, and it's not a folder for projects. Basically, Areas provide a flexible means of handling tasks which aren't part of a "project" and aren't necessarily sequential in nature. In the words of Cultured Code:

With an Area of Responsibility (or simply "Area"), you don't ask yourself about the desired outcome, but what standards you would like to maintain. An Area corresponds to an ongoing activity. These could be, for example, job responsibilities, roles you have taken on in your family, or personal responsibilities like health.

Things is available for download as a free trial, and can be purchased for $49.95US. Things Touch, the iPhone version, is available in the App Store for $9.99US.

My search for the perfect software task management solution has been going on for a long time, and I think I've finally found the answer: Remember the Milk for iPhone (iTunes link). I've tried almost all of the big names in task managers: iGTD, Things, OmniFocus, and even Leopard's built-in todo functionality. None of them have met my needs.

For me, a task list needs to be ubiquitously available, and very quick and easy to interact with. For me, that means I need a native iPhone app, which immediately eliminates iGTD and Leopard's To Do list, since there is no iPhone equivalent. That leaves me with Things, OmniFocus, and RTM, all of which now have native iPhone apps.

One of my requirements is that my tasks synchronize to a web server, so that I don't need to have my laptop turned on to synchronize my tasks to my iPhone. This eliminated Things as a contender for me, since it currently only supports direct synchronizing over the same wireless network. OmniFocus had therefore been my de-facto task management tool due to its ability to synchronize both the Mac and iPhone versions to either MobileMe, or your own web server using WebDAV. The main problem I've had with OmniFocus on the iPhone is how incredibly slow it is to start up and synchronize. A recent update attempted to address this issue by allowing new tasks to be added while the synchronization was occurring, but it's still just not quick enough.
