IPhone apps, is there any app or way to spy on another iPhone

I'd like to get my boyfriends text messages because he deletes them before I see them, when he's being shady he keeps his phone by him at all times until he's done having the conversation then ends it an deletes help! I wanna know if I can retrieve deleted texts or if there's an app that will send me them!

If you don't trust your boyfriend then why are you with him?

Use this site. It's free for 16 days and works on text, Facebook and tells you their location

You may use an ios monitoring software like ikeymonitor: http://ikeymonitor.com/

If you can actually get hold of your boyfriends phone then use http://www.enigma-recovery.com/smartphone-recovery-pro2/ its a pen drive that takes 5 minutes to recover all deleted text messages and contacts and call history and more. Good luck, but be prepared to deal with what you see.plus if you really don't trust him you should not be with him.
