How to Use Sunday Nudge

Everything happens over text message. No app, no account, no login.

Getting Started

When your number is added to Sunday Nudge, you'll receive a text asking for your consent. Reply YES to activate your account. Until you reply YES, no reminders will be sent to you.

Setting a Reminder

Just text naturally — no special format required.

–Call Joe Tuesday 2pm
–Dentist appointment March 12 at 10am
–Pick up kids Friday at 3:30pm
–Team meeting tomorrow at 9am
–Remind me 30 minutes before my 3pm call with Sarah

The app will confirm what it understood and ask you to verify before saving anything:

Create: "Call Joe" on Tue, Feb 24, 2026, 2:00 PM. Reply YES to save or NO to cancel.

Reply YES to save it or NO to discard it. If the app couldn't understand your message, it will ask follow-up questions to get the details it needs.

When Your Reminder Fires

At the scheduled time, you'll receive a text like this:

Reminder: Call Joe at 2:00 PM. Reply DONE if complete or SNOOZE 15 to snooze.

DONEMarks the reminder as complete. Nothing else happens.

SNOOZE 15Delays the reminder by 15 minutes. You can snooze between 5 and 120 minutes — just change the number.

Commands

You can send these any time:

LISTShows all your upcoming scheduled reminders.

DONEMarks your most recently fired reminder as complete.

SNOOZE 15Snoozes your most recently fired reminder by 15 minutes. Change the number for a different duration (5–120 minutes).

Deleting an Upcoming Reminder

If you want to remove a reminder before it fires, text DELETE. The app will show your upcoming reminders as a numbered list. Reply with the number to remove it.

DELETE

Which reminder do you want to delete? 1. Call Joe — Tue, Feb 24, 2026, 2:00 PM 2. Dentist — Thu, Feb 26, 2026, 10:00 AM Reply with the number.

Deleted "Call Joe".

Recurring Reminders

Include every day, every week, every month, or every year in your message to set up a repeating reminder.

–Take vitamins every day at 8am
–Team standup every Monday at 9am
–Pay rent every month on the 1st at 10am
–Dad's birthday every year March 12 at noon

The confirmation will show the recurrence so you can verify before saving:

Create: "Team standup" on Mon, Feb 23, 2026, 9:00 AM (repeats weekly). Reply YES to save or NO to cancel.

Once saved, Sunday Nudge automatically schedules the next occurrence after each reminder fires. To stop a recurring reminder, use DELETE to cancel the next upcoming occurrence — that stops the chain.

Tips

–Relative dates work: "tomorrow," "next Tuesday," "this Friday"
–Specific dates work: "March 12," "April 3rd at 2pm"
–Lead times work: "remind me 30 minutes before my 3pm meeting" fires the reminder at 2:30pm
–To be reminded at a specific time, just say that time: "Call Joe at 3pm" fires the reminder at 3pm
–Conversations time out after 20 minutes — if you start scheduling something and walk away, just start over with a new message
