I have experience with TODO....which I used until Toodledo came out. I was using TODO and syncing with Toodledo online so it made since to give Toodledo a try. TODO was torquing me off because I also had Appigo's Notes program and was running into data issues when I was syncing both with Toodledo.
Switched to Toodledo a couple of weeks ago and not looking back. It supports subtasks which makes it work much better for tracking work projects with multiple tasks.
I hear lots of good things about Things as well....no pun intended but I don't have any direct experience with it or Omnifocus.
Thx.......all advice is good for me. I know the apps aren't really that expensive, but I like getting the best the 1st time around. I'm hoping user experiences like yours could help me make my decision.
I've used those 3 apps and right now I'm using OmniFocus. I love it, although it may be an overkill for most people's needs. Between Things and Todo I like Todo better.
Edit: In the Omnifocus website there's a quickstart video of the app, you can check it out to see what you think.
I use Things in connection with the desktop version of the program. (Mac only) Works like a charm. The only negative thing is, that Things has no alarms.
I have definetely decided I will not be paying for Omnifocus. I will admit I bought Things & ToDo. I don't like ToDo at all. Things was much easier to figure out and just had options that I appreciate more. I think I will go check out iCal Tasks now.
