Pretty buggy but worked eventually, happy with the result. For a while it wouldn't connect. Even if WiFi is connected to the backpack, the app might say that there's no connection. You have to tap the top left corner connect option and then select WiFi and just keep tapping on the buttons (Find device / next connetion) until it works. I had to tap them multiple times. After that the app has a lot of options. It even lets you download your own fonts which is cool.

This is one of the worse apps I have ever encountered. I purchased one. Hadden used it in a few months. Oh boy, the problems it gave me including tears because I really needed it that night when it wouldn't work. Then I bought 2 more for family. They having problems as well. How dare these people let people buy a product with this much trouble and tell them they can return it. Who the heck wants to return something so nice after being able to initially being used. Redeveloped the app.😡 😡 😡.

English Translation of this app needs a major overhaul. Also, can we have a option where we can disable some animations then enable them again later or change their order? For everybody else, this app works with backpacks that have a YSP-001 LED backpack screen which depending on what backpack you buy may be WiFi or Bluetooth enabled. (Get a backpack that uses the Bluetooth version or find a Bluetooth version of the screen. It'll be easier to use.)
