Thank you very much for recommending the Legentibus app. I've just installed it, and I'm already enjoying it. It looks nice, has just the right amount of introductory material, and runs smoothly, which already puts it head and shoulders above most apps. I'm looking forward to diving in.

I had four years of Latin in junior high school and high school, and have been trying to revive my skills using Duolingo for five minutes a day for a few years. It will be fun to try something new.
