Ham newbie, already to five characters at 20 wpm!
I cant get over how terrific this app is. Its on my apps "front page" of my iPhone. I started using this app a week ago and am already up to five characters at 20 wpm! I find the practice very relaxing and look forward to my daily practice session. Being able to practice at any time by simply pulling out my phone is truly a blessing and its apps like these that really make my phone useful.
A note/tip: You can copy and paste the output of an exercise by taping on the "display" and then selecting copy. I then paste this into my notes app (Evernote) to make it easier to grade myself later. Also, be sure to read the informative notes via the "i" icon at the top right of the display.
