The experience was ok

I was scared when I thought my phone got hacked so when I downloaded this app I thought the names were legit until I found Shazam😂😂😂

The final solution

I’ve tried most of the major VPNs around. Guardian is the o only one you can really forget about. Just turn it on and never goes back to it. It just works. If you’ve tried a few VPNs you know what I’m talking about. There’s no way you don’t have to access it at least once every other day. You also get a firewall for your iPhone. I really recommend it. Can’t wait to have Guardian available to macOS too!!

It’s works Well!

I downloaded the app a few days ago thinking it was some video game. However, when I start the app up I realized it was a VPN. I decided to keep it and it’s safe to say it does work. It blocks every tracking program and tells you who’s been tracking you. It also does a decent job as a VPN. I decided to keep it and I suggest you check it out. The app is neat and easy to use. 10/10!
