User reviews
My partner and I both use this and it’s a great app. First time I used it it found a bunch of bad files that I think I accidentally downloaded one time and didn't know where they went. Great to know that it will find and remove anything bad from my phone. Thanks!
I wish they had a VPN, I’d be signing up for that too. Apart from that the app is top notch. I had Certo on my last phone and it was the first app I put on this phone when I got it from the store. The scanner and other parts of the app are really easy and simple to use, even for a non-techie like me. 5 stars.
Excellent app for anyone worried about cell phone privacy. I have it run a scan every day on my cell and it works great
The most beautiful app actually detailed and precise.✍🏿
I keto a tight watch on my phone and know what's what I downloaded just to give it a try to see if it would recognize anything it told me exactly what I already knew that's good that's tells me it is doing its job I would recommend this
So far I like this application and will continue to use it.
