I have always been surprised at how great it looks! A lot of effort is put into analyzing the colors and sheets to make it look good and easy on the eyes! love it

Only works properly with Chrome. On firefox, its way bad then u can imagine.

非常感谢开发者，很棒，晚上能好好玩手机了。

When you enable dark mode it doesn't work properly. Also what is not mentioned is that if you try to scan a QR in e.g. whatsapp web it doesn't work until you disable dark mode.
