Custom menu items on mobile devices

I just built my first website (www.pharmintuition.com) using Catch Everest Free. I am very happy with how it looks but noticed a couple of issues on mobile devices. I made two custom menu placeholders ('About' and 'Services'); these are not clickable themselves, but hovering over them brings up sub-menus. On a PC (Windows 7) and Macbook, they work just fine - hovering brings up the sub-menus. On an iPad, the submenus do not appear and on an Android phone, selecting the menu item leads to a page not found error. Is there a way to fix this? Thanks in advance! (By the way I could not post this in the Catch Everest Free forum - it says I need to be logged in, though I clearly am...)
