How to recover deleted data from iPhone 5 without baked up by iTunes or iCloud?

A relative on mine lost all his items (including photos, videos, contacts, apps) by accident and he didn't back his iPhone 5 up not even iTunes. So, I/we researched solutions for how to recover your photos, videos, contacts and stuff without iTunes and/or iCloud and we got iMobie PhoneRescue. It's a website that recovers lost data. All you have to do is download the program itself into your computer, once that's complete, you click recover from IOS device and so on. So, my other problem is that I already downloaded it and I keep clicking recover from IOS device like said but it won't let me! Ahh! *Note::: I don't know if this website really works and whatever but ill take my chance. There's a free download and trial.it's a 5 star website! Anyway, please look it up and tell me what's wrong with the process of it!

A good way to recover deleted data such from iPhone 4 without backed up by iTunes or iCloud is to download asoftech data recovery software.
