Loved by thousands of iPhone and Android users alike

Very happy with Certo's app. I am not very technically minded but I found it easy enough to use. Also it doesn't seem to slow my phone down or pester me with ads like lots of other apps. Would definitely recommend it.

Best malware detection and removal you can find. I’ve been using this for about a year now and would recommend to anyone. I have an antivirus app as well but I always keep this app on my phone as I think it’s a deeper scan. Good additional features as well.

Installation was a breeze and the software is so easy to use! You just plug your charger into the computer and your phone and scan! That’s it! Thanks for the peace of mind Certo!

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 researched this app after my Facebook account was hacked. I was concerned the person may have accessed my entire phone. Certo helped me to rest easy that my OS was intact! A must have app in this day and age.

Certo made checking my apple iPhone and iPad for viruses and malware so easy. I wish I would have gotten there program sooner. Their customer service is also top notch and friendly staff.

Not only does Certo have the best customer service, they were easy to install and the scan was what was promised! I would recommend this company to anyone who wants to make sure their phones are safe. Best of the best! Thank you Certo team!
