This works on the iPhone but, was not built for it. Looks best on desktop or iPad

Adobe Muse – $14.99 (muse only) to $49.99 (all Adobe Apps) a Monthly or Annual Subscription – Though this is a subscription app I really like this one. You get access to about 500 or so Web fonts that you do NOT need to code for simply select the font and it does the rest. I will admit that the interface may be a bit intimidating for some users but, this app gives you a lot of flexibility & features (like built-in slideshows)
An extremely potent and versatile tool. If you have done design work with a page layout program, then you’re ready to work on web sites using this tool. Intuitive and straightforward are the words that come to mind. You can “try it out” for three months by buying a license from Amazon. You will be impressed!
I also recommend the book: Don’t Make Me Think–A Common Sense Approach To Web Usability.
