VERY buggy

I thought I'd give this a try for saving rtfs. I pasted in text with color and links. All looked fine. Then:
1) tried changing color on part of text-very limited options.
2) tried making a section of text smaller, end of text was not visible-could not scroll to it
3) tried saving-could find no way of saving or going back to a document list (of doc was auto saving)-app crashes while I was looking!
4) tried again to change doc size-bottom lines were truncated again.
5) when changing size or color, hyperlinks in my pasted text were removed!
6) dumping this app-want the past 10 minutes of my life back


Many good features; a few flaws

This is a great word processor and works really well for those of us who use Siri to dictate a draft or brief document. If you pause before you say "period", it is smart enough to enter "."

Biggest gripe I have is that the app says it is optimized for iPhone 5, but good luck reading the name of your files without an old-timey magnifying glass. I'm guessing it was ported from OSX and nobody really looked at that aspect of the interface. You can't do a zoom to bring up the size of the text on the file list, and all you see is the truncated file name in itsy-bitsy teeny-tiny letters.

Does the trick

Simple text editor for when pages is just too much. Please update graphics for retina display iPads. (Font sizes are small and graphics are fuzzy). Make interface more intuitive. Otherwise simple and has the ability to move files between apps is great! :)
