iOS spelling apps

Hi. I am looking for 2 different types of apps for spelling on iOS. I am wondering if any such things are in existence and if they are, what are they called? 1. An app where I can say a word and the spelling of it comes up on the screen so I can rotor through it letter by letter. 2. An app that I can paste text into from the clipboard and have that text checked for spelling errors and if any are found, they can be corrected before having the corrected text pasted back to the clip board. Thank you.
