Verdict
The clearest difference is price: TwinViewer at Free against Image Blender's $3.99. TwinViewer also leads on update cadence (every 5 weeks vs every 4 months) and iOS requirement (16.0 vs 26.4). Image Blender's advantage is rating (4.9 vs 4.0) and in-app purchases (none vs 1). On ads and device support there is nothing between them.
