Comments on N5SLN Morse Trainer — Learn CW for Android
★★★★★Daynah Rodriguez· Jul 8, 2026
Just downloaded this app, and this is one of the best morse trainer I've done. It does a few similarities with LCWO which I love. And the pro is only $4.99, which I truly believe is worth it.
★★★★★Kerem Söke· Jul 12, 2026
So far this app is the only one gives you real practice and experience. Others only makes you match the letters to more code but this one makes you listen and experience real time. Loved all the modes but wish it had TA/TB/TC/YM
★★★★☆Chris Johnson· Apr 19, 2026
I've tried several morse trainers and this seems the best. I have found one problem: the text input on the text player function does not accept keyboard input properly, and apparently paste doesn't work there either. Fix that and it's easily worth five stars.
