The clearest difference is in-app purchases: Background Remover at none against TwinViewer's 1. Background Remover also leads on update cadence (every 3 days vs every 5 weeks). TwinViewer's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
