Does anything have a recommendation of how to learn Morse today? maybe an app? the app the author recommends is only for iOS and I have Android
Note that visual learning is not recommended for the simple reason that you want to have Morse ingrained and recognized automatically when listening, not translate it consciously. It's like learning any other system of symbols for active use: you want to know at once what you're hearing or seeing, not leaf through cheatsheets, even if they're in your brain.
