One of the Best Morse Code Straight Key Apps I have ever found. It does so much more than practice morse code!!! Or chat!! For example, you can write a note or email, using the straight key. Copy the text. Drop it into a text editor. Convert Case, check spelling, and you can send it. Well done.

I bought it especially because of its Morse keying feature, and it's pretty functional, the best I could find for Android. I haven't tested the other features yet, but they'll be useful for me too (Caesar ciphering, microphone and camera decoding, preset messages, etc.). One thing I'd suggest is the addition of a dark mode. Also, the clear button could have a setting to toggle disable/enable the need of confirmation before clearing the text fields.

Excellent. Working superb. But there should be a provision to change the frequency/tone of the code audio and to adjust the Farnsworth (gap) speed. I personally feel the code audio tone as a little harsh. Hope the developers will include this also in the next update.
