Verdict
The clearest difference is price: Mariners at Free against Chip Day's $1.99. Mariners also leads on ratings volume (61 vs 1) and iOS requirement (14.0 vs 17.0). Chip Day's advantage is update cadence (every 3 days vs every 6 months) and review sentiment (100% vs 92%). On rating, ads, in-app purchases and device support there is nothing between them.
