I guess I don't know if it does what it really says it does. It's funny that when it cleans junk files, it only cleans its own files. It seems that you have to close the same apps within a minute five or six times, first with battery saver then with internet booster then with something else. I'm not even sure it really closes the apps. It says it does but I am doubtful. You're not supposed to get notifications from apps that have been closed, but they keep on coming.

It's annoying but have it since I believe it works. It pops up on everything I open on my phone, the ads are of no interest for me. I keep getting a notice my data is breached and being sold to 3rd parties, I thought it was covered under the defender. So that is what bothers me in regards to annoying. Thank you for reaching out!

The perfect security app and efficient cleaner. I've had this app for awhile and had no problems. Its the best optimizer ever. Makes your device run like new. A must have. One thing Ive notice which you really need to put on your app would be a way to list all apps not to be closed. I have tried to keep these apps open but your app keeps closing these apps. I guess its called a "White List". If there is any way it could be added that would be wonderful. Thank You. Works beautifully.

T" for Thursday "T" for THANKS for your review! Make sure you have enough space on your cell phone to save these moments. We recommend using the dfndr function: App Cleanup function. This function suggests you uninstall the apps that you use the least and thus have more space on your cell phone.

What's new

Thank you for using dfndr security! =) Let's get to the news!
- In this version, we made bug fixes and performance optimizations to make the app even better ;)
And did you see the new Quick Cache Cleanup? This feature has been improved to be even more efficient. Check it out!
