RingDue

WhatsApp-first call reminders

Reminders that actually ring.

Tell RingDue what you cannot miss. WhatsApp verifies your number automatically, then RingDue turns messy text into real reminder calls with retries when needed.

Call me at 3:30 to pick up Tara from drawing class

Incoming call - RingDue

Drawing class at 4:00 PM

Your daughter's drawing class is at 4 pm. Please get her ready.

Answer

Snooze

Tap Continue with WhatsApp. The setup message is already typed.

Tap Send. RingDue verifies the sender phone and explains what it can do.

Send reminders, calendar protection, snooze, cancel, or backup instructions in chat.

One WhatsApp message becomes a real call.

RingDue keeps onboarding inside WhatsApp and keeps the web app as the control surface. The product explains what will happen before it ever places a call.

Tap the WhatsApp link

The setup message is prefilled. The sender phone becomes the account identity, so there is no phone-number form for the normal path.

Tell RingDue naturally

Messages like “call me at 4 for my daughter’s drawing class” are parsed into time, subject, spoken note, recurrence, and backup behavior.

Get the call and recover misses

RingDue places the phone call, speaks the useful reminder, then supports cancel, snooze, retry, calendar protection, and escalation from chat.

Built for how reminders are actually missed.

WhatsApp is the capture layer. The phone call is the reliability layer. RingDue is strongest when a quiet notification is not enough.

No app friction01

Start from WhatsApp

Open WhatsApp, tap Send on the prefilled setup message, and RingDue verifies the sender number automatically.

“START. I want RingDue to call me for important reminders.”

India-ready capture02

Natural English and Hinglish

The assistant is designed for messy real messages, including Indian reminder phrasing. Hindi voice-note intake can come after text reliability is stable.

“Kal subah 8 baje gym ke liye call karna.”

Real interruption03

A call, not another ping

RingDue is for the reminders that cannot disappear inside a notification stack: classes, pickup, medicine, client calls, renewals.

“Call me at 4 pm for my daughter’s drawing class.”

Missed-call recovery04

Retry and backup escalation

If the first call is missed, RingDue can retry or call a trusted backup contact when the user explicitly asks for it.

“If I don’t answer, call my wife.”

Calendar guard05

Protect important calendar events

Connect Google Calendar, then ask RingDue to call before selected meetings or recurring event types.

“Call me 30 minutes before every calendar meeting.”

Parents and caregivers06

Specific spoken notes

The call should say what the user actually needs to do, not repeat a vague title. This is where RingDue differs from a normal reminder app.

“Your daughter’s drawing class is at 4 pm. Please get her ready.”

Business beta07

Renewals and appointments

Gyms, clinics, coaching centers, and tutors can use RingDue for high-value reminders where a missed renewal or visit costs real money.

“Call members 2 days before subscription renewal.”

Trust controls08

Consent before calls

Phone verification, opt-out, pause, and clear reminder lists matter because a product that calls people must be more careful than a chat bot.

“Show my reminders” · “Cancel medicine” · “Pause calls”

Checking phone

RingDue needs a verified number before live reminder calls. WhatsApp handles this without a phone-number form.

For reminders you ignore everywhere else

RingDue is for appointments, school pickups, medication, and work calls that are too important for another quiet notification.

Calendar protection without a dashboard

Connect Google Calendar, then ask RingDue to call before selected events or every meeting that needs protection.

Designed for missed-call recovery

Set retries, snooze over WhatsApp, or add a backup contact for reminders that need a human safety net.
