The clearest difference is ads: Okayama Garbage Sorting App at none against PlateMask's shown. Okayama Garbage Sorting App also leads on iOS requirement (15.6 vs 18.5). PlateMask's advantage is update cadence (every 9 days vs every 13 months). On price, in-app purchases and device support there is nothing between them.
