Verdict
The clearest difference is in-app purchases: Odd One at none against Butterfly Surprise's 1. Odd One also leads on ads (none vs shown) and update cadence (weekly vs monthly). Butterfly Surprise's advantage is review sentiment (100% vs 92%) and iOS requirement (13.0 vs 17.0). On price and device support there is nothing between them.
