Completely FREE to-do list organizer, that allows you to create categories. Absolutely beautiful app that works on pc/mac/iphone/ipad/android
For a more full-featured team-oriented app made by the same people, visit wunderkit.com (or see my review of it).
This is the best To Do list app out there. You can download it for your desktop and for your iPhone/iPad or Android and it syncs automatically.
You can create different lists for errands, tasks, groceries, etc. I was able to set reminders on my iPhone but couldn't do it on the website. You can even print and email your list.
You can even email a task to your list:
Just send it to *******@wunderlist.com (you have to send it from the email account your registered with)
Subject: Enter the list name
In the body: list the tasks and put an * next to the ones you want to star.
Had this resource advised by my friend. I`m already using it for a month or so and this planner is good enough for all my needs. I recommend!
I use this app daily to keep track of passwords, timelines, due dates, and keep team members in the loop. I even keep my grocery list here too!
