Verdict
The clearest difference is ads: AStamp at none against KNOW TV's shown. AStamp also leads on update cadence (every 2 months vs every 12 months) and monetization model (free vs ad-supported). KNOW TV's advantage is device support (4 vs 2) and iOS requirement (12.0 vs 18.6). On price, rating, ratings volume and in-app purchases there is nothing between them.
