The clearest difference is price: 4=10 at Free against Glyn's $1.99. 4=10 also leads on rating (4.9 vs 4.6) and ratings volume (2.5K vs 93). Glyn's advantage is in-app purchases (none vs 1) and update cadence (every 8 days vs every 2 months). On ads, device support and iOS requirement there is nothing between them.
