Anvitha Vijay, nine, has created many educational apps. The young girl from Melbourne, Australia, learned to code( 编程 ) at the age of seven. Soon, she was trying her hand at making apps. "When I first got my iPad, I was interested in all the apps on it, "she said. "It wasn't long before I wanted to create my own. " She built her first two apps with her younger sister. Smartkins Animals helps children identify animals. Smartkins Rainbow Colors teaches kids colors. Each app has been downloaded thousands of times. Anvitha's skills gave her an opportunity to attend a big meeting hosted by Apple in San Francisco, California. There, she got tips from experts. She went to workshops where she learned about the latest software such as Sketch for app building. All that raining led to an idea for a third app. This one, called GoalsHi, helps kids to practice good habits. Users are rewarded for achieving goals, such as eating their vegetables or practicing the piano. Anvitha says the rewards are like getting a sicker( 贴纸 ) for a job that they do well. "Kids can set goals with this app and get stars when they achieve them," she says. "The idea is to encourage kids to achieve one little step a day." Anvitha's goal is to continue creating apps that help kids learn while having fun. But even more important to her is that the world sees the power of technology in kids' hands. "The more training we get in technology at an early age," she says, "the better chance we have of becoming a person who will one day change the world.”
