Love the ease and efficiency. Awesome app. Very informative and insightful if wanting to know more about your device. The added breach check.is a great bonus. Check any email of they’ve ever been named in a data breach from years ago. Sweet tool. Love it highly recommend.

This app is good if you need to identify certain vulnerabilities on your iPhone. If you have any issues, their customer service was quite helpful and responsive.

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

My son who works in IT suggested I try this app after I was getting lots of strange messages and things happening on my phone. Since running it once a week I have had no viruses or malware problems. I also got a VPN app so I think with both I’m all set!

Does exactly what it says. Clear to read and understand. This is now the second iPhone we’ve used it on and would certainly recommend this app.
