Verdict
The clearest difference is in-app purchases: AlienRuins at none against Summer Time's 3. AlienRuins also leads on device support (4 vs 2) and iOS requirement (15.0 vs 18.0). Summer Time's advantage is update cadence (every 7 months vs every 25 months) and price ($0.99 vs $4.99). On ads there is nothing between them.
