Verdict
The clearest difference is ads: Piedra at none against Samples Pro's shown. Piedra also leads on update cadence (every 10 days vs every 4 weeks). Samples Pro's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 17.4). On price and in-app purchases there is nothing between them.
