Verdict

The call

The clearest difference is review sentiment: PDFDarkMode at 100% against PDF Pro's 60%. PDFDarkMode also leads on monetization model (free with in-app purchases vs subscription) and update cadence (every 4 days vs every 2 months). PDF Pro's advantage is ratings volume (6.9K vs 1). On price, ads, in-app purchases and device support there is nothing between them.
