About this app

This application does absolutely nothing. It was originally created for Android development and testing. It is useful for testing application condition detection, app launching and killing, and auto task killer priority management.

Unlike other "nothing" apps, this actually does what is described. There is no blank window. There is no UI, and the app icon is transparent.

So, i had this app in my playstore wishlist for over something like 2 months and i never downloaded it, until now. I'm leaving 5 stars because it does exactly what it says it does. Also, TO EVERYONE WHOS SAYING THAT IT DOES NOT OPEN, ITS ACTUALLY SUPPOSED TO BE A COMPLETELY BLANK APP FOR TESTING AND ANDROID DEVELOPING PURPOSES. also can the dev of this app reply to this lol

Thank you! So many people don't read the description and leave a bad review 😕

I'd leave another star but it doesn't play pornography which is a little disappointing. I read black cock and not black screen by mistake. Other than that I'm super happy with my app and it's boundless potential.

This app works very well for me when paired with the "Target home launcher" by BH_lin. I do not want or necessarily need a home screen so this helps a lot. Thank you.
