I need a light-weight web-based note keeping application. The app should be runnable on Android/ iPhone. I need such an app because I find that I do grocery shopping once in a week, and by the time I get to do shopping, I forget what I want to buy already. So I can jot down my necessities in my daily life and view the list when I'm doing the shopping.
Is such an app already available?
Gmail task is a good choice. But it is a bit too general.
Edit: Thanks for all the recommendation! But I would prefer the one with OpenID support even though it has less features, rather than the one without with more features.
