### 5/5 — Great app

*2018-01-16*

Thankful this app keeps me updated on what’s up with me iPhone.

### 5/5 — Best ever

*2017-11-06*

Awesome

### 5/5 — Love it

*2017-10-22*

Its amazing

### 5/5 — Ability to tell me if I’m hacked

*2017-10-12*

When you choose either version paid or free it will tell you if your jail broken. Jail broken indicates your vulnerability and hacked. It does say potentially unprotected but it gives the reason. The reason is my server or carrier. I’ve decided to download Norton to all of our cellphones. I have Norton on all computers. So, I will get it for all phones. Thanks for educating me of importance to protect my phone from hackers or shall I say VULTURES!!

### 5/5 — Quick information

*2017-10-11*

When this application is started, you are given a quick, informative analysis of your system! It was good peace of mind to find out no issues were found on my device. It’s not necessary to get paid the app but it’s only $1 to get rid of the advertising.

### 1/5 — It does NOTHING!

*2017-10-10*

It just shows usage but does clean anything! This app is totally useless! Too many ads. Wants you to buy the pro version to do any cleaning

### 1/5 — This does nothing.

*2017-09-20*

Don't waist you time with his. I think the 5 year old who wrote this is having a good laugh.

**Developer response:** Hello,

SystemGuard has unique features compared to other security apps. We take the scan our app provides very seriously.

Sincerely,
SystemGuard Developers

### 5/5 — Good app

*2017-09-17*

Works great for protecting your device

### 1/5 — Sorry to say

*2017-09-15*

Sorry to say but this app is a piece of junk. It does nothing but offers to upgrade for $$$. Waist of time.

**Developer response:** Dear Kolobok757,

SystemGuard does offer a unique security check for free, this is not something our competition can offer. You also don't need to upgrade to the Pro version or buy the In-App purchase.
If you have any questions, feel free to contact us by e-mail.

Sincerely,
SystemGuard team

### 5/5 — Get it

*2017-09-14*

It's good to see if you have virus or not
