Verdict
The clearest difference is in-app purchases: Nano Notes at none against Project Iris's 1. Nano Notes also leads on ratings volume (150 vs 13) and device support (4 vs 2). Project Iris's advantage is update cadence (every 4 days vs every 3 months) and review sentiment (100% vs 83%). On price, ads and monetization model there is nothing between them.
