Hey, everyone . I am an android developer, mainly developing free apps, my recent app is Super App Lock, which is now released in google store. Link not allowed here I guess, so here is the package id: com.superjoy.applock . It has no ad and free.

I am busy developing the Christmas version, so new looks will come out.
Some people say the lock page is too simple, and too dark, I think I will change that in next update.
By the way, there will be apps coming. Though I need money, but first of my apps will all be free, and forever free. Anyone install it, thank you very much!
