I have come across an app called Dyslexia Tool Kit. It is written by a dyslexic for a dyslexic. It costs around £4 and can be bought from the Apple Appstore for iphone and ipad.
For Google play- play.google.com/store/apps/...
It looks to be a useful self-help guide with lots of good, practical information as well as providing reassurance and reinforcement that others have the same or similar issues and advice on how to combat the feelings associated with them.
There is a lot of sensible, practical help/advice for further education students and the introduction for parents is encouraging.
