What were you doing at the age of fourteen? Emma Yang, a fourteen-year-old Chinese-American, has developed an app for Alzheimer's patients. Called "Timeless", the app uses facial recognition technology and artificial intelligence to help patients remember important things. It is to be launched by the end of this year. CGTN'S Nina Edwards has more.

By eight, she was playing cello. But this young teen, born in Hong Kong -- where she lived for ten years -- has more than just musical talent.

EMMA YANG DEVELOPER OF "TIMELESS" APP "I love to code. I began coding when I was six years old when my dad introduced me to a programming tool called, Scratch, where you can drag & drop different blocks of code to make a program. I was amazed at the extraordinary range of things you could create with code. Whether it was simple or complex, it was my own personal creation that was special and unique that I could share with the rest of the world."

Emma decided to use her coding skills to help her grandmother -- who suffers from Alzheimer's disease and still lives in Hong Kong.

EMMA YANG DEVELOPER OF "TIMELESS" APP "My grandmother essentially really raised me, especially because, you know, my parents were working during the day. So after school, she would pick me up and I would- she would look after me while I did my homework and watched TV. And then we would talk together. And so, you know, we were actually really close while I was growing up, uh, especially because, you know, I actually spent a lot- most of my time with her outside of school. As a family member of an Alzheimer's patient, it's hard to feel in control of the situation. Coding is a place where I have complete control over what's going on. So, I developed, Timeless."

Emma's timeless app is still in development. But since winning the 50-thousand-dollar grand prize in a startup challenge co-hosted by women who tech and Google, Emma can move to the next step - getting timeless into the hands of patients.

EMMA YANG DEVELOPER OF "TIMELESS" APP "In the beginning, it was just for me and my grandmother, I thought. But you know, as this grew, I saw this feedback from online and social media and articles that, you know, this is actually an idea that a lot of people thought would be great for their families and people that they knew who had Alzheimer's and which is really motivating for me because it's not something that's just for me, but for a whole community of Alzheimer's patients and so, that's what really motivated me, that there are people out there who could really benefit from this."

COLE COLISTA KAIROS CHIEF TECHNOLOGY OFFICER "To see the quality and the thoughtfulness that Emma had put into her app was amazing if she had been a college student or a graduate student, never mind at her age."

While Emma may be a teenager with big dreams, don't let her age fool you. She believes coding can change the world and, with dedication like hers, she just might be right. Nina Edwards, CGTN, America, New York.
