This app goes through the letters alphabetically and you key in each letter multiple times before moving to the next.
This is really a poor way to learn and does little for listening comprehension.
Perhaps it gets better later, but I’m not wasting my time to find out.
For comparison, look at the letter sequence and methodology in the MorseMania app. I tried this one because it was free and other apps make you pay for advanced features, but seeing this I probably will pay.
If you’re at all serious about learning Morse code, skip this app.
