If you're a hacker in need of a Mac/iOS todo list, I couldn't recommend TaskPaper (http://www.hogbaysoftware.com/products/taskpaper/) enough. It's a hybrid outliner and todo list, but scales from simple lists to multi-project, tagged lists with loads of notes and documentation.

Best of all, the file format is plain text, so you can keep it in source control, edit it in Vim (there's even a vim plugin - https://github.com/davidoc/taskpaper.vim), or whatever you want.

I bought TaskPaper both for iOS and Mac and I've been very disappointed.

At first, it looks great but the Dropbox sync'ing is completely broken. I was losing data many times a day and ended up giving up on it. Many have reported sync'ing issues on their forum as well. That's too bad because I really liked it otherwise.

Sounds like org-mode, except it is free and open source with tons of great add-ons. MobileOrg for iOS which is also open source.

What greatly inconvenienced me about MobileOrg was having to manually push and retrieve changes from the app, which led me to the occasional "but I'm sure I've captured this!" moment. Call me stupid, or even inconsistent for hoping something a little more brainless (it's an emacs mode I'm trying to sync with, after all), but eventually it put me off from adopting it in full.

Yeah, that is definitely a pain point with it. I have a list of things I would like to change, but it is pretty low on my list. Also the code isn't exactly how I would've built the app, so it is a little discouraging to work on in my free time.

As a org-mode user I've been using TaskPaper quite a lot (before getting back to org.) It's very good on its own, but org-mode is way more powerful
