Papua New Guinea's girls just got a period tracker built with them, for them — and it works offline

Periods are hard to manage when nobody will talk about them and the nearest clinic is hours away. Oky PNG, launched by Save the Children, UNICEF and Papua New Guinea's government, is a period-tracker app co-created with girls aged 10 to 19 — the first of its kind tailored to the country. It teaches menstrual health, puberty, personal safety and mental health, points girls to help when they need it, and — crucially in a country where internet access is still spreading — it works offline once downloaded.
