It's pronounced wanderfull in Norwegian
The one current paying user of the app I've seen in this discussion called it "Wanderlog". FYI on the stickiness of the current name.
"Wanderful" would be a better name.
Just FYI, I would read it out loud in English as “wander fuggle”. I would assume most Americans would pronounce the ‘g’.
I thought ‘wanderfugl’ was a throwback to ~15 years ago when it was fashionable to use a word but leave out vowels for no reason, like Flickr/ /Tumblr/Scribd/Blendr.
And how many of your users are going to have Nordic backgrounds?
I personally thought it was wander _fughel_ or something.
Let alone how difficult it is to remember how to spell it and look it up on Google.
