After going through what seemed like every horrible task list available, I came across this one, and its the best by far. Its cute, its easy and very simple.
You have the option to make separate lists or categories of tasks, to make repeatable tasks, give them priority colors, set specific times and dates, set alarms, view old or past tasks and set tasks with no specific date in mind. All very easy to learn and there are extensive instructions found within the app. Best app Ive ever bought!
Update: If developer reads this, it would be nice to be able to edit or delete the "Default" list name. It gets a bit annoying having to select a list every time when most of my tasks fall under the "Work" category I use and would be convenient to set the "Work" as default unless I change it.
