Here’s a quick tip; have you ever wanted to create a daily, but weekday-only, repeating task in iOS Reminders? The UI is rather limited but the functionality does exist.
Siri to the rescue!
Simply tell Siri something like:
Remember to pack a lunch on weekdays
Siri will offer to create the reminder for you and it will have a custom repeat setting. Once created you wont be able to view/edit the repeat settings in Reminders, but thats not a huge deal since it’s simple enough to ask Siri to create you a new one!
