Verdict
The clearest difference is price: Merge Dogs! at Free against GTS Colour's $0.99. Merge Dogs! also leads on update cadence (every 3 months vs every 22 months) and ratings volume (25K vs 1). GTS Colour's advantage is in-app purchases (none vs 6) and ads (none vs shown). On device support and iOS requirement there is nothing between them.
