Verdict
The clearest difference is in-app purchases: Ratios at none against Zero Note's 2. Ratios also leads on ratings volume (79 vs 1) and device support (3 vs 1). Zero Note's advantage is update cadence (every 3 days vs every 5 months) and rating (5.0 vs 4.7). On price and ads there is nothing between them.
