My search for a means of tracking tasks continues. In the cloud, I tried out Remember the Milk, Ta-da List, Todoist, and Toodledo. Of these, Toodledo is my favorite, but ultimately I wasn't happy with it either, and in any event I really wanted a local app rather than a web-based solution, because I want my data kept locally and I want to be able to use it when I'm offline.
In the app world, I tried the Jira bug-tracking system, which is free for personal use, but it is far heavier-weight than I need for this purpose. I tried AxoSoft OnTime and FruitfulTime TaskManager, but didn't really care for either of those. Things looks really nice, but it's Mac-only. My current favorite is Tudumo. It's simple and well-designed, and while it isn't quite perfect, I have few complaints. I like that it is designed with simplicity as a primary goal, it is GTD-friendly, it is reasonably priced (though not free), it has a generous 60-day trial period, and it gives me full control over my data (it will export CSV). If I end up sticking with it, I'll make a later post about how I think it could be improved.
