Verdict

The call

The clearest difference is ads: Reaction Time at none against Rune Circuit's shown. Reaction Time also leads on device support (5 vs 1) and iOS requirement (15.6 vs 17.0). Rune Circuit's advantage is update cadence (every 5 days vs every 2 months). On price and in-app purchases there is nothing between them.
