Beautiful but maybe not useful
I'm never fond of apps that you can't figure out without looking at documentation. Sure, some apps do things so complex that you need help but something like this should be obvious.
While you can tell that people have posted about their travel and you can see very beautiful pictures and posts (many I'm certain are from the developers) what you can't do and what makes this app a fail for me is search. Sure, maybe some of us are just wondering where we might want to go and have the cash to choose from anywhere but most of us have a general idea of a location.
Maybe you're going to Europe and you have a list of countries you're considering. Want to find them on this app? Well sadly there's no search for countries that I can find so you're out of luck. Best hope you can find stuff browsing.
I have to add that I've not set up my profile or blogged from this site because honestly, I'm never going to write a blog post on my phone and why would I change over from my set up blog to this one?
Make it easier to navigate and this app would be a win but for now it's only useful if you're not looking for specific countries and information.
