Natuba is the original iPhone photo sharing site.™

It’s the easiest way to put your iPhone photos on the web for your friends to see and discuss.™

After getting iPhones, we began taking photos on the go and soon realized we needed an easy way to share them with our friends. Although there were plenty of photo sharing sites on the web, none of these sites were designed specifically for iPhone users. So we created Natuba, a site for uploading, sharing and viewing photos from your iPhone.
