As a Non-Impaired College Student and Application Developer

As someone who has developed other apps, when I used this subway app, it contains really necessary functions and is easy to use. When the iOS version comes out later, I think more blind people will be able to get help. It's a really great app, and great job!

As a Director at the Woori Dongjak Center for Independent Living

Frequently, the visually impaired have difficulties in getting off the subway train because the information about the destination station was not provided due to the noise around them. We are very grateful that the students noticed our difficulties and made such a convenient app.

by Yoon-Taek Kang

As a Visually Impaired Customer

It’s really easy to use for me when I commute by subway every day. Especially, it is a very convenient application that shows only the necessary contents without complicated contents. It informs you how many stops are left until arrival and an alarm goes off when you arrive. I can also call subway officers for help in an emergency.
