MorseCode Mentor

I'm a Voiceover user and a huge fan of Morse code! When I first downloaded this app awhile back, I ended up deleting it after a couple minutes' usage because I didn't think it was intuitive enough to use with Voiceover. I've just redownloaded it, and boy, was I ever wrong! The WHOLE THING is FULLY accessible to Voiceover users! Even the dot and dash buttons in the Learn tab are clearly spoken by Voiceover! Even so, I try to practice typing the required character in Morse code with Voiceover off so I can get the rhythm of it. I do have a couple suggestions. First, when I type the Morse code in the Learn mode, there's a bit of latency between when I tap the dot or dash and when I hear the sound of it. The developer needs to improve that so I can practice typing each character at a faster speed. Second, there ought to be a Settings button (represented by the ⚙️ icon) with options for the user to select the characters THEY want to focus on in the Learn mode, as well as setting the playback speed (WPM) of the code. Also, there ought to be two exercises in the Learn mode: the typing exercise that's in there now, and a listening exercise for practicing reception of random characters or words. For the listening exercise, there could not only be options for which characters to focus on and the WPM of the code, but also, for words, the maximum number of letters for any word to have. Other than those suggestions, I see NOTHING wrong with the app! I'm impressed with it!
