Verdict
The clearest difference is review sentiment: Nano Notes at 83% against Watch PDF Reader's 29%. Nano Notes also leads on price (Free vs $4.99) and rating (4.8 vs 3.1). Watch PDF Reader's advantage is update cadence (every 3 weeks vs every 3 months). On ads, in-app purchases and monetization model there is nothing between them.
