Why another GTD app?
Over the last years I have tried a lot of task management applications. I was always trying to improve the status quo, where I forgot some things I wanted to do and didn't have a possibility to jot things down when I should have. For the last 2 years Things was my task manager of choice. With the iPhone companion app I could add tasks on the go and sync them to the Things database on my MacBook. The fact that it was only possible in the local network was acceptable, since cloud sync was announced with priority.
Over time I added an iMac and an iPad to my setup. This made t(T)hings a bit more complicated. Syncing between the iMac and MacBook is much more complicated. I chose to sync my Things database file via my DropBox account to all my computers. But this means that only one instance of Things can be running at a time. If I forget to close the app on one machine, the data will probably not be up to date or even overwritten. The iPad can sync natively with the Mac application. But then again only via the local network. I also didn't want to pay half of the price of the desktop application for a solution I'm not satisfied with. And I didn't want to setup some VPN/Wide Area Bonjour solution just to sync my tasks. And there is still no over-the-air sync solution in sight.
The main problem is apparently that this syncing and scaling stuff is really hard. Which is also the reason why systems like CouchDB don't exist. Don't get me wrong, I don't think you can solve this (in a satisfying way for developers and customers) by just throwing a piece of technology at it. But I also don't think this is we-have-to-think-about-it-for-2-years hard. Needless to say I am a bit disappointed how this turned out. And due to this I also used Things less and less, which didn't really improve the situation.
So I started to try out other task management solutions. The obvious choice was OmniFocus. It has great syncing support and device integration. However I just want a simple solution and OmniFocus can do pretty much everything ever imagined regarding task management. So it is a bit bloated to use. Other notable choices are Todo for iPad/iPhone in combination with the online syncing service. There is no Desktop app however and I have the feeling, that the data is rather closed in.
One really good looking alternative is wunderlist by the Berlin based company 6 Wunderkinder. There is a Desktop and iPhone app and there is also online syncing built in. This is really a promising todo manager with a clean interface. But I also wanted the possibility to have my data in my own personal cloud.
CouchDB to the rescue
As I had started to work a lot more with CouchDB lately, I decided to built a GTD manager as a couchapp. This meant I get replication, simple storage and the REST API (almost) for free. Additionally it supports a completely decoupled approach to interface with the data. The first step is of course to write a couchapp to be served directly from CouchDB. This can then be used to access the data from everywhere. And can also be replicated together with the data to any device supporting CouchDB.
For the next steps the CouchDB HTTP/JSON API also enables the easy creation of clients for the data in almost any language or technology. Therefore a console, native OSX or iPhone client or even a much better web client can be created rather easily. And all this while your data remains under your control. Just get a CouchDB and get started.
Use this now?
That being said, gtd-couch - the couchapp mentioned before - has just reached version v0.1.0. It already features basic functionality and is pretty usable. Try it out if you're interested, I use it as my task manager already. There are also some outstanding issues and new features which will be implemented as time allows.
This does not mean that I won't try out the Things cloud sync solution, when (if) it finally comes out. I still think it has really great design and a simple interface. But for now I'll enjoy being able to interface with my data as I want to and host it where I want to.
