Knowing they are fine when you cannot call
With Athnova Care, your parent gets one WhatsApp message a day in their language. A check-in at 9:00 am in India reaches you at 7:30 pm (the day before) PST or 8:30 pm (the day before) PDT — so on most days you know they have taken their medicines before your day starts or ends. If they do not reply, they get a reminder and then a phone call, and you are alerted. Caring for parents in India from California →
