How to send WhatsApp reminders to friends without a new app

Set and send reminders to friends directly on WhatsApp—no installs, no shared calendars.

You can send reminders to friends on WhatsApp without adding another app or sharing calendars. Tell Coco who to remind, when, and what to say; Coco delivers the nudge on time.

To start, add the contact once, then send a plain-language command: “Remind Jake Friday 9am to send the invoice.” Coco schedules and delivers it, and you get a confirmation. You can stack multiple reminders, edit times, or cancel with a single follow-up message.

Keep messages short and specific: who, what, and when. Coco handles timezone shifts, recurring follow-ups, and avoids adding clutter to your own calendar. Try it for vendor invoices, quick project nudges, or family check-ins.
