I spent some time and completely re-design and re-coded the default theme for my app Lumo: https://lumo.me
Checkout one of my albums here: http://drew.lumo.me/nature
If you haven't signed up yet, try it out! Even has an iOS app for uploading to and managing your Lumo site.
Main difference between Lumo and other photo apps is it's for all your photos. Not just ones you take on your phone. In fact you can't even take a photo with the iOS app, and that's on purpose. Lumo gets you a beautiful photo website super quickly for showing off your best photos.
More new themes coming soon too! :)
