? Can’t Set Reminders
While you can set timers and alarms while offline, this doesn’t apply to Apple’s Reminders app, which is unfortunate as we think the ability to simply call out “Remind me to…” is one of the most useful features of Siri.
There don’t seem to be any technical reasons why Apple couldn’t allow this, since Reminders doesn’t require an internet connection, and dictating reminders is very straightforward — in fact, the language isn’t all that different from setting an alarm — so we’re hoping it comes in a future iOS update.
