Verdict
The clearest difference is in-app purchases: FlexSpec Backpack at none against AntWave's 1. FlexSpec Backpack also leads on iOS requirement (9.3 vs 15.0). AntWave's advantage is update cadence (every 2 months vs every 24 months). On price, ads and device support there is nothing between them.
