Verdict

The call

ルーレット! and 7 both sit at 4.8 stars, but that hides the real split: 83% of ルーレット!'s written reviews are positive against 36% of 7's. ルーレット! also leads on update cadence (fortnightly vs every 3 months) and iOS requirement (12.0 vs 18.0). 7's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, rating, in-app purchases and device support there is nothing between them.
