Very helpful – Glyph Mastery Review

Great way to learn glyphs. It is effectively interactive flash cards. It's the best I have found of its kind. Not to be thought of as an Ingress scanner simulator: different color, no sparkling animation or sizzling sound, one glyph at a time. Suggested improvement is to simulate real world glyph frequencies so we learn the common ones first.
