I am on an iPhone 6 with iOS9.1 Good: App has a great interface for a free download and works as an html editor except for problems below. Bad: After reaching the bottom of a page, I was unable to scroll down to continue typing or see what was behind my keyboard. The syntax highlighting only picked up html not javascript even when I gave the document html tags and put my js in script tags. I also tried saving the document with a .js extension but the highlighting didnt change. Lastly when I saved my document and returned to the main menu then clicked on the document again it had reverted back to the first time Id saved it (with 3 characters in the page) so I lost my entire block of code. Overall: Looks great and functions(ish) but has some major bugs that need to be addressed.
