Still testing it

Haven’t written anything with this yet though getting to know the program a bit, those who work in freelance might be seeing a 33 year old attachment getting mileage on a different operating system. Still seeing how this might operate may help my classmate and cousin on their anthology 📝


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.
