Up to around 2016 when the original founders swapped to a subscription based business model it was quite relevant or at least I thought so back then, I started using it around 2014.
It didn't have live monitoring or any of the "bells an whistles" that came after that. I was essentially just a malware scanner a bit like VirusBarrier Scanner is today.
True to form the iOS version includes a VPN (doesn't everything?), call and text filter, web protection, ad blocker, spam blocker, identity protection and more.
Interestingly the only thing it doesn't do is scan for Malware.
