This is GREAT practice. I use it for my middle school Latin students - they actually WILL use this app to practice recognizing tenses. I think it’s fun in idle moments, but it does get them to use what they know to make a reasonable stab at what they don’t. I am Mac all the way - but my students - and my school are Windows. That’s the one thing I’d want - a Windows version, since in spite of my best efforts, I have not converted the school, let alone the world.
