# ProKnockOut vs Background Eraser

The clearest difference is in-app purchases: Background Eraser at none against ProKnockOut's 12. ProKnockOut's advantage is ratings volume (74K vs 354) and update cadence (monthly vs every 3 months). On price, rating, review sentiment and ads there is nothing between them.
