Verdict
The clearest difference is price: Live CRM at Free against Ductulator's $3.99. Live CRM also leads on update cadence (every 2 weeks vs every 2 months) and rating (5.0 vs 4.7). Ductulator's advantage is ratings volume (353 vs 3) and chart position (#54 vs unranked). On ads, in-app purchases, monetization model and device support there is nothing between them.
