Recurring tasks, reminders, emails or deliveries. Anything where you have something that should re-occur on some schedule.<p>What is the best UI that you've seen for configuring this?<p>- Free form text field, i.e. typing "every 24 hours"<p>- Classic form, dropdowns and radio buttons (examples would be appreciated)<p>- Crontab...<p>- Something else entirely
A lot of what is "best" has to do with how specific you want to be. Appending "every" to a date is great if you want something to occur every N. But what if you want it to occur every other N? Or the first N of every M? There's a reason why things like Crontab or iCalendar's RRULE are so specific and verbose.<p>In order to decide what is "best" I would first decide how specific I needed to be and then start to narrow my input options based on my defined need.
