A Portuguese-language service sends medication reminders through WhatsApp and alerts the next caregiver when a dose goes unconfirmed.

Why it surfaced

Na Hora Certa is built for a specific, familiar problem: keeping track of a parent’s medication without making them install another app. Its workflow combines one-tap confirmation, repeated alerts, caregiver escalation, and a history for the doctor, with a family plan listed at R$29 per month for up to three people.
