Morse Mentor for Android

Slowly but surely in still learning Morse code. I’ve been using, but I’ve discovered that that is really limiting my potential practice time. I haven’t tried many apps, but Morse Mentor seems to offer most of the same features as lcwo. Koch method, Farnsworth timing, etc. I’m working with character speed at 20wpm, but Farnsworth of 5wpm. I’m doing well at that speed, but I know I’ll have to speed it up a lot to get on the air. I hope to be proficient at cw and have a QRP rig built by the time I go to Burning Man this year. Oh and I hope to get my general class ticket!
