Für das iPhone gibt es das App CWSpeed. Damit lerne ich zur Zeit. Einfach und gut.

Description: •Uses Koch's training method (the most efficient known to date)
•Accurate morse code timing
•For beginners as well as experienced operators
•Target speeds from 12 to 40 WPM (60 to 200 CPM)
•Farnsworth timing, 5 to 40 WPM (25 to 200 CPM)
•Non-tiring, high quality audio (wave shaped, no key clicks)
•Free try-out app available (CWSpeed Lite)
Its a very nice app for practice your CW skills, both for a beginner and for someone who wants to improve their speed.
You always have it near at hand when you get a few minutes without nothing to do.
I know morse already but its great for improving your speed. And I think it will also be good for beginners.
The app is very easy to use.
Sound is great, both in speakers and phones and the app has a clear and easy navigated user interface.
