I used to use Nozbe, but found it didn't sync well on Android. I've since moved to Toodledo. In order to fully utilize Toodledo, you may need "subtasks" (aside from that, the only hierarchy is folders containing tasks), which require a $15/year "Pro" account.
This is the public group instrumental rationality diary for the week of October 15th. It's a place to record and chat about it if you have done, or are actively doing, things like:
Or anything else interesting which you want to share, so that other people can think about it, and perhaps be inspired to take action themselves. Try to include enough details so that everyone can use each other's experiences to learn about what tends to work out, and what doesn't tend to work out.
Thanks to everyone who contributes!
