Verdict
The clearest difference is in-app purchases: Avkin at none against SAM4 Online's 1. Avkin also leads on update cadence (monthly vs every 6 months) and ratings volume (13 vs 1). SAM4 Online's advantage is rating (5.0 vs 4.7) and iOS requirement (12.2 vs 15.1). On price, ads and device support there is nothing between them.
