While we're working on easier ways to set up recurring medication or treatment for specific days of the week in the future, the best way currently is to create 3 different routines, each on a once per week interval (every 7 days): One starting on a Monday, the next starting on Wednesday, the third starting on Friday.
Let's say that you want to create a medication (e.g. Azithromycin) schedule for Monday, Wednesday, and Friday that repeats weekly.
iOS
Let's start with setting up Monday.
Tap on "Manage Questions" on the bottom menu > tap on the "Add" button
Search for the medication > Schedule: Set to "intervals" of every "7" days
Set the nickname to "medication name - Monday", and configure the date to start next Monday.
Repeat steps 1-3 for Wednesday and Friday. Now you're all set!
Android
