AVG Secure VPN and Proxy and AVG Mobile Security

I'm in a bit of a muddle.
Q1 ) Is AVG Secure VPN and Proxy for I phone mobiles a constituent part of AVG Mobile Security?
 Q2) If not what are the differences between the two programmes?
Q3) How many Apple devices (  phones an I pad) can I run on the above two programmes? 

I downloaded both but seem to have four ( two each) subscriptions on my Apple account ready to trigger payments when the trial periods are over.
I am hesitant to put the Order ID numbers on this Blog for security reasons. I tried to unsubscribe from one of the AVG Secure VPN and Proxy accounts thinking I would be left with one functional AVG Secure VPN and Proxy programme.The 4 subscriptions remain on my apple account. The AVG Secure VPN and Proxy App now does not work. The AVG Mobile Security App does work. 
What do I want?
I want security for my I phone 7s.
I want to understand the difference between the two programmes.
I may opt to run both once I understand the difference.
I do not want to be charged 4 times for two programmes.
Please hep.
Kind Regards
Geoff Dobson

Hello Geoffrey.
We'll be glad to clarify this.

AVG Mobile Security for iOS is an app designed to protect your privacy online, securely store your photos, scan Wi-Fi networks for vulnerabilities, and alert you if any of your passwords linked to your email address have been leaked online. It is not an AntiVirus app. VPN is included with AVG Mobile Security, so you need not download AVG Secure VPN and Proxy separately.
