Yeah, perhaps the developer needs to consider whether ALPConnect still supports iOS 7, as the appstore still says it does ;

Compatibility: Requires iOS 7.0 or later. Compatible with iPhone 4S....
My 4S runs nicely, and is jailbroken on 7.1.2. I'm worried that upgdrading it to the latest iOS will cripple it performance wise.

What iOS version are you running on your 4S Tom, and what is the performance like ?

Cheers
