Verdict

The call

The clearest difference is in-app purchases: FlipFlapReferee at none against Whystl's 1. FlipFlapReferee also leads on iOS requirement (17.4 vs 26.0). Whystl's advantage is update cadence (every 5 days vs fortnightly). On price, ads and device support there is nothing between them.
