Alarm app with repeats every.____ days?

[Mike_Luchia]

Hey all,

Is there any Alarm Clock app that allows you to schedule an alarm that repeats every X number of days instead of checkboxes for the days of the week you want the alarms one? I work a 4 day on, 4 day off rotation and I'd love to be able to set 4 alarms that repeat ever 8 days. If this was possible I wouldn't have to change the alarm repeats every week.

Thanks for any help.

Mike
