There are enough themes, which are claimed to be responsive. However not all of them offer the full compatibility of mobiles devices. All elements and sections in theme are handcrafted after multiple debugs and tests on various devices. We tried to solve all issues regarding mobile web browsers, proper margins and paddings.
Retina Display is supported in our theme. It means, that each single element is coded and not a single image is used. This results on a far higher resolution on Retina (High Resolution) devices like iPad, iPhone.
