You have been able to set repeat alarms with Alexa from the beginning, but now you can finally set a repeat reminder. To do so, just say something like “Alexa, remind me to [task] on every Monday at 7 a.m.” The advantage of a reminder versus an Alarm is that reminders speak out the task you set and don’t need to be turned off when they sound. Alexa will just play a tone a few times, speak out the task, and then go silent on its own. So if there’s something you need to be reminded of on a regular basis, but it’s not so important to merit a full alarm, repeat reminders are the new way to go. Big thanks to @Erinescence for the heads up.
