This program teaches you to receive Morse code (CW).
It starts with two letters and adds more when it sees that you are ready. This is the easiest way to learn code because the computer thinks about the practice you need next instead of wasting your time with stuff you already know or confusing you with stuff that you don’t.
The original idea comes from Ward K9OX (http://c2.com/morse/).
The app uses the Koch method letter sequence and starts with the first two letters: K and M.
For Each letter you have a column showing how high is your error score. It starts from 100 and lowers as you start guessing letters right and increases when you are wrong or you take too much time to recognize it.
SETTINGS
WPM (Words Per Minute): let you set the speed of the CW playing. The suggested speed is 20. The minimum is 15. You should choose a speed that does help you focus on the sound of each letter and not on the dits and dahs.
CW TONE: choose a tone frequency that suits your ears. Default is 700Hz
LESSON: sets the lesson level. By default you start with lesson 1 (2 letters) and as you get confident with them new ones are addedd.
MINIMUM LEVEL: sets the minimum average error level before adding a new letter.
RESET SETTINGS: resets the error level of each letter back to 100%.
The app can be found here:

Any feedback and suggestion is more than welcome!

Excellent app. I really enjoy it 🙂
One question about the “minimal level” setting:
Does 25% means that a new char is introduced when i read 75% of the chars correct ?
I ask because (for my personal feeling) the app introduces new chars very fast and i
Would like to slow this down a bit (i mostly use the app in the subway. Not the perfect
Environment, of course).

Thanks a lot! I’m happy that you like it.
The 25% is the average error level of all the letters.
Each letter starts with 100% and, depending on how fast you guess the letter, the error level can go down up to around 3%. If you feel that it goes too fast you can decrease this value but not too much otherwise the already learned letter will be repeated too rarely.
I found that 25% is a good level. But feel free to try other error levels and see what’s the one that better suits your needs.

I agree. An option to choose only numbers, letter or punctuation would be helpful. Also it would be good having some kind of results register in an order to evaluate progress. Another interesting option could be sending groups of letters. I find myself with near no mistakes at 20 wpm and 4 secs of no warning but I’m stuck on the quantity of letters I’m able to “process” in 10 min. If I reduce the “no warning” to say 2 sec that’s a bit of a disaster. I suppose I just need to put some more work! Bst rgds & 73.

Love this app but if I could change one thing would be to be able to disable the hint letter or have the letter only appear after the morse sound has been replayed x times. I sometimes miss the first attempt to recognise a letter but on hearing it again would get it, having the letter show spoils that for me.

Ciao Andrea,
I bought this on Play Store (Android) and I have to say I like it a lot but I had to refund it since I have an issue. When the letter starts, the first quarter/half second is silent so it get’s hard to understand what letter has been played. For example, “U” is sometimes a dot and a dash, sometimes just a dash, never the entire sound. Do you have any idea how this could be solved? I think your app is awesome and would really like to be able to use it!
Thanks,

Hello David,
that’s strange. It’s the first time that it is reported.
Are you using any kind of bluetooth audio device to listen to it? Because sometimes Bluetooth audio devices take a little to start playing sound (exactly about 1/4 – 1/2 second). If so then the solution is simple. Use a wired one or listen to the phone directly.
If that’s not the case, then unfortunately I have no idea of what can cause it 😦

Ciao Andrea,
I joined an online Morse class to learn the code, but it is your app that is really doing the the most for me! It is fantastic!!! Many thanks to you for the work you have done. I have learned a few things in my efforts to learn the code. Most important – Don’t be old! Even with that hurdle your app, which I am mainly using on a PC with an Android emulator, is the best! You are doing a great service for those who can access your program.
If I may I would like to suggest a few ways to make the program a little more flexible.
#1 The ability to turn off the programmed teaching routines to allow a full character “pop quiz” of all the characters without first having to complete a full programmed letter sequence.
#2 The ability to enable or disable any number of the characters for the same reason..
#3 A text to code player to allow hands free copy practice.
#4 Native PC operation.
Please don’t feel insulted by my suggestions, Yours is the only program I would even expend the effort on to try to improve.
By the way I have tried many other apps, but ONLY yours is a contender for the best. Followed by Wolphi’s Morse Trainer for its tremendous flexibility, and Morse Toad for it’s sense of fun! I would definitely pay more money for your program.
Sincere Thanks and 73 from an old man,

Hi,
Initial trials of the new version have been very positive, apart from the occasional sending of two chars together – which I assume is the reason for the latest Bugfix. Personally I preferred the previous interface, but it’s hard to see how that would work with the multi char “top words” option.
I noticed the permissions have changed to include full network access and wonder what the reason is for this?

Yes the new version is a first step towards fixing this bug but not yet perfect. Later this week I’ll release the definitive fix.
I’ll soon be adding the possibility to record your statistics and key progress so that you can use the app on multiple devices and take with you your progress.
Also maybe I’ll add a global leaderboard and who knows some sort of distance challenges between users to add a little bit of fun to the whole process.

Hello Again Andrea,
I have installed the update on my phone, but haven’t yet done it on my PC. I wanted to be sure I liked it first. I Do! However the lack of the hint and the clear highlighting of the key that has been pressed has also caused me to delay my PC install. The old app has this and I find it useful. I hope you will consider these things on a future update. You have previously said that the hint will be back. Thank You.
Is there a way to roll back the update on my phone until a little bit later ( or perhaps the location of an archived .APK file) ? I appreciate that these are small things, but still useful to me. If I had enough years left and the drive to do so I would roll all of the best features of your program, “CW (Morse) Trainer” by Wolphi, and “Koch Morse Trainer Pro” Into one super program usable on all platforms. The demand is surely there! But I am getting on in years and you can’t have everything. I am deeply appreciative for what you have done for us.

Hi,
Out of curiosity I have just installed the MM app onto my Chromebook – it works really well
But… just a quick thought:
As I have a real keyboard in front of me it seems a shame not to be able to use it rather than stabbing at my screen.
Would it add a huge overhead to the code to add hardware poll for a keyboard (real / bluetooth) at startup and if found add a keycode scan to for suitable devices?

I'm still running a few tests now, but its looking like this may be my preferred platform for future app dev.

yes is a nice idea. The only problem is that usually voice recognition relies on online services. I have to find a way to make it work fast and offline. Maybe using some ML and some initial training. We’ll see.
