habiter isn't a todo list. it's for things that you'd like to do on a constant basis, like cleaning your room or going on a run.

get habiter by running gem install habiter in a terminal

went for a run today? want to keep going on runs?

just habiter did run

how are you doing on keeping up with your habits? run habiter log

habiter is, of course, open source. It's a little thing from the imagination of Tom MacWright
