Complete setup on the Astumi website, then use the conversation on your iPhone. There is no separate Astumi app to download today. ## can I set daily or repeating reminders? Yes. Ask for a one-off reminder, a daily check-in, specific weekdays or a repeating interval such as every 30 minutes. Include the activity and schedule, and wait for confirmation that your reminder is saved. ## will umi message me first? Yes, when a reminder you requested is due. Just mentioning a goal does not save a reminder. Ask explicitly and wait for confirmation. Delivery times are approximate. ## can I change or cancel my reminders? Yes. Ask in the conversation, identifying the reminder you mean. You can change the time, cancel a reminder or skip a date on a daily or weekly schedule. Wait for umi to confirm the change. ## does this connect to Apple Reminders? No. umi reminders are managed in your conversation and do not sync with Apple Reminders. umi sends a message at the scheduled time; it does not provide an alarm guaranteed to override your iPhone’s Focus or silent settings. ## which timezone does umi use? Reminders use the timezone saved during setup. If you travel or are unsure about a time, ask umi to clarify the saved schedule rather than assuming it follows your phone’s timezone. ## how much does it cost? You can review the current subscription offer during signup before subscribing. No separate App Store purchase is needed. ## how do I stop messages? Send STOP on its own to stop messages and request cancellation of future subscription renewals linked to your phone number. This does not refund the current period. To stop one reminder, ask umi to cancel that reminder instead. ## one less thing to keep in your head.
