"...if you're looking for [a to-do app] with more functionality, Appigo's Todo is one of the better options, and it doesn't require a Ph.D. in Getting things Done (GTD) to figure out how to use it...well worth its $10 price tag."

"If it's a to-do list you need, you can't do better than Todo by Appigo."

Can I add a due time (in addition to the date) to a task?
As of Todo 1.4, you can enter a due time for a task. If you are using Toodledo / RTM as a sync service, you may be able to set up SMS messages for all tasks that contain a due time. Alerts can also be configured in Todo based on a task's due time setting.
