HEALIOS Online therapy

Hi all, 

I'm wondering if anyone has had any experience of Healios. If so, what impact has it had? 

My 15 year old has been under CAMHS for the last six months and has been diagnosed with depression, PTSD and anxiety. He was diagnosed with high functioning autism when he was 6. 

He's been through the group therapy under CAHMS and he's now going to be referred to something called Healios. I'd never heard of it before. It's basically 121 counciliing through the app on a facetime/Skype basis. It looks really good and for my son it sounds like it would work really well but it sounds too good to be true.  Does anyone know anything or had experience with this? 

Many thanks x
