hey so currently i work 5 days a week (Week A) and then week B i do 6 days a week meaning i work the Saturday aswell, they are all early starts so at the moment i am using the default IOS alarm clock waking me up at 4am Monday - Saturday meaning on week A Saturday the week i don't work on the Saturday, i am getting broken sleep and becomes really annoying waking up and they trying to get back to sleep

i am trying to find a app that will let me set some sort of a 2 week cycle thing so that i can set an alarm clock for every 2 weeks to wake me up on Week B Saturday, if anyone knows of an app or has the amazing skills to make one that would be amazing :) i use a iPhone 6S with the current os
