For those who find the increasing growing list of task lists daunting, Random Reminder offers you a button with several common reminder prompts to help trigger what common task you need to do, but you end up putting off.
The app comes with some built in reminder prompts, but you can easily customise this list to add or remove as much or as little prompts as you need.
Finally, you can add a reminder prompt into your calendar so you can actually plan the thing you were meaning to do, but for one reason or the other you always delayed.
