Verdict

The call

The clearest difference is price: Gun Idle at Free against GTS Colour's $0.99. Gun Idle also leads on update cadence (every 4 months vs every 22 months) and ratings volume (59K vs 1). GTS Colour's advantage is review sentiment (100% vs 65%) and in-app purchases (none vs 3). On device support there is nothing between them.
