WhatsApp-first onboarding
Start RingDue from WhatsApp.
Tap the button, WhatsApp opens with a setup message already typed, then tap Send. That one message verifies your phone and opts you in for reminder calls.
1
Open WhatsApp
RingDue creates a private setup code and fills the message for you.
2
Tap Send
Your WhatsApp sender number becomes the verified call number.
3
Tell RingDue what to remember
Example: "Call me tomorrow at 7 AM for medicine."
