One tap each morning. The whole family sees the green light at the same time.
Each morning the senior parent taps a single button: I'm okay today. The check-in immediately shows up green for every family member in the family group.
If the check-in is missed by the configured time window, family members get an SMS notification automatically. No more pit-in-your-stomach mornings spent trying to decide if Mom is just in the shower or if something is wrong.
