MorseTest for Android

This app teaches morse code the correct way, by sound only. All the other apps I found show the characters visually, which will mess you up when you try to go faster than a few words per minute.

Once you learn all the characters, the "random" group of 5 letters becomes predictable and repetative. This can give you a false sense of accomplishment.

Solid 599 for this portable, customizable CW trainer. Great for turning down time into practice sessions, I like to use it on airplanes especially. This has been one of the tools that helped get me from 5 to 20 WPM in spite of the sunspot drought! As a ham, it's one of my favorite Android apps.

This app will be very helpful in getting my skills back. However, at higher speeds, if you try to copy individual letters without being able to hear common digraphs, trigraphs, and words, you'll hit a big wall. Gordon Brown's tapes didn't teach that way for the 20 WPM test. I don't think it's going too far to say that random letters, at higher speeds, are limiting. Don't get me wrong -- this is a very useful app, and I think it deserves four stars. The author should look up the "Dissociated Press" novelty text generator. He can take a bunch of text from QST, or from typical QSOs, to build a table of which letters, probabilistically, follow single letters or pairs. "Playing back" the latter can generate very plausible, but random, text, with the "right" numbers of "th"es and the like. If he can work that in, this program would deserve six stars, and $3.99.

This is a great idea and the closest I've seen to what I want in a morse code practice program on Android. However, there are several bugs and annoyances. For example, the program sometimes starts sending and cannot be stopped with the stop button. In this state the sound is sporadic or non-existent. The Settings sliders are sometimes hard to activate. With some speed settings, the characters are run together. All of these things can be fixed and I look forward to the updates. One minor wish is for the characters to appear (in Show mode) right after each is sent, rather than before. That fits how one would write, type, or visual the characters.
