ok Mamy - I have one of pretty exactly the same but mine are for telephone numbers.
Mamy - what I am amazed at - if the person who can't spell - how does she enter the words to be spelt (if she doesn;t really know them bless her) you know what I mean
I'm not sure as to whether pocket spellcheckers can do it but, on a PC, simply typing a rough guess at a word into a Google search will often find the correct spelling (without needing to go any further).
It says in the reviews that someone tested it as suitable for a child by deliberately misspelling words, so it must correct - or give you a list of alternatives.
