I'm making a simple app using an app maker that will countdown a half-hour period of time every Friday and Saturday. Of course, the app maker doesn't have that capability, so I'm looking for a timer/alarm that I can set by days and times, including looping every week, and multiple times on those days, on line. This needs to be linkable. If I create this countdown on a site online, a simple solution to my countdown app is to link to the page I already created.
None of the alarm pages I've found so far allow for setting alarms for specific days. It'll set for time, even multiple times, for specific dates (like a holiday), but not for every Friday and Saturday.
Hope this isn't confusing.
