A simple, and very cool, mayan calculator and decimal conversion app. Tap or drag a glyph onto another glyph in the glyph pad to combine them. Dots can be dragged to bars, and bars to dots.

Simply tap on the digital display (at the top), when the keyboard slides up enter the digital value. Tap Done to dismiss the keyboard and see the Mayan glyphs representation.

Verdict
The clearest difference is price: Coronado USD at Free against Mayan Math's $0.99. Coronado USD also leads on rating (5.0 vs 4.7) and iOS requirement (13.4 vs 16.6). Mayan Math's advantage is update cadence (every 5 weeks vs every 5 months) and ratings volume (6 vs 1). On ads, in-app purchases and device support there is nothing between them.
