Very easy and intuitive, very easy to use LED signage app
Now, I cheer on my cell phone and decorate it in my own style.

- More diverse cheering effect intuitively saves fun and style
- You can create and save the cheering traces you made, or delete them if you don't like them.

Not only is it the best for concert trot support, but also an LED sign that can be usefully used when catching a taxi on the road at night.
Everyone's support will brighten up a dark place, everyone is common~
