Verdict
The clearest difference is in-app purchases: Compendro at none against Prism Notes's 2. Compendro also leads on iOS requirement (15.0 vs 18.6). Prism Notes's advantage is update cadence (every 4 days vs every 3 weeks) and device support (4 vs 2). On price and ads there is nothing between them.
