Excellent learning tool just got better – Signal Flag Master! Review

I learned the signal flags in record time with this app, with greater ease than I could have imagined. I drill whenever I find myself waiting in line at the supermarket. In an earlier review I remarked that I only wished I could have an app like this for the semaphore flags, too. It looks like Gareth must have read it, because within days, we have semaphore drills available, too! Outstanding! Thanks ever so much.
