Verdict

The call

The clearest difference is monetization model: Sign PDF at freemium against eSign App's subscription. Sign PDF also leads on review sentiment (100% vs 85%) and rating (5.0 vs 4.8). eSign App's advantage is ratings volume (1.5K vs 1) and chart position (#83 vs unranked). On price, update cadence, ads and in-app purchases there is nothing between them.
