Verdict
The clearest difference is in-app purchases: Lettermix at none against Zen Gems!'s 4. Lettermix also leads on rating (1.4 vs 1.0) and ratings volume (12 vs 1). Zen Gems!'s advantage is update cadence (fortnightly vs monthly). On price, review sentiment, ads and device support there is nothing between them.
