This worked well to clean and free up space a couple of years ago, but now it's just a flurry of ads and fake buttons (push one and download a whole other mess). They've even positioned the x right next to download buttons, so rather than exit, one may just get a surprise new app installed. It's nothing short of annoying now, so I'm removing Nox completely. Please don't ask me to reach out to you.. there are already too many options out there for second chances.

Hello, We're deeply sorry about the problem we've made. Since all of our features are free, earning through ads helps us provide users with better services. At the same time, we'll continue to minimize advertising display as much as possible. If you have more questions, please feel free to contact us. Email:

It works well. It actually cleans and opens up space. But...! It sometimes send fake messages like, "200mb ready for cleaning!" or along those lines and I just cleaned it. If I go and clean it again, it says it's fine and there's nothing to clean. Also, it takes up a lot of space for an app that I'm using to free up space. Those are my only problems.

UPDATE: Now when you run the Memory Booster option, it wipes out whatever wallpaper you have set on your screen; so you have to reset your screen. Everytime they have updated this app, they add more and more advertising to it and makes it run worse. And as of the last update, now it deletes text messages, phone logs, some emails. It's crazy. They should have left well enough alone. Time to switch to a new app!
