Verdict
The clearest difference is price: Rhythm at Free against pdfManager's $0.99. Rhythm also leads on rating (5.0 vs 4.0) and ratings volume (3 vs 1). pdfManager's advantage is update cadence (every 4 months vs every 8 months). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
