The following settings are available:

Five different learning modes are available in Morse Trainer

- Random groups of X mode: Morse Trainer will play groups of X randomly selected letter, numbers or special characters. X can be an amount between 1-9. Those characters can be individually selected. If you want to learn just "s","i" and "e" just select the 3 letters and Morse Trainer will create groups of X with those 3 letters.
The characters can also be chosen from 20 lessons of the Koch method.

- Real ham radio callsign mode: Morse Trainer will randomly play real amateur radio callsign from a database of 5000 callsigns which appeared in Contests over the last couple of years.

Good, but trying to get to the screens where you set the characters or send speed settings etc is a bit glitchy, it doesn't always appear when want it to. The actual sending of morse is really good..very flexible what different characters you want to hear, speed and group length, it's just getting to the settings in the first place that is sometimes problematic. One star dropped because of the glitch.

Firstly, great app. My only wish is regarding 'Own Text Mode'. If you could add a 'Randomize' option to it would be great. Then users could put common qso words, Q codes, rig names(Icom,Yaesu,etc.) and hear them randomly instead of in order. I have had this app for a couple years messing with it every now and again. I've been solely using this app for the last month and have made more progress than ever before. Thank you so much for providing this app freely.

This app is sufficient for beginning CW training. Sometimes the randomizing callsigns just don't make sense, sometimes the characters don't match the audio - especially so at slower speeds. So learning qso formats can be frustrating. It got me started but I think I'll be moving on.
