Do you know http://www.hikr.org ? It seems to fulfill the same purpose. It's centered on Europe and reports are mainly in German and other West European languages, but there's an English-speaking community on there, too. It has been around for a couple of years, has a huge community and tons of hiking reports already.

How is Hikify different?

Also, I think the copy of the three steps could be tightened. Something like "Find an interesting route near you - Climb it - Log your achievement and share your experience and your pictures."
