Possible to have an exit grabber which is compatible with iphone browser?

I doubt it.

You should really think about what you want to achieve with an exit grabber. It sounds like rather unfriendly behaviour. Perhaps your time would be better spent improving the website so that user's don't want to close it in the first place.

 

God I hope not. Personally, I boycott any site that uses that sort of approach, and will not buy anything from it under any circumstances.

 

dear exit grabber,

No one likes you. No one. Not event the people that own the site.
