Verdict
The clearest difference is price: ET0Edge at Free against Leafscan's $19.99. ET0Edge also leads on update cadence (fortnightly vs every 104 months) and iOS requirement (13.0 vs 15.6). Leafscan's advantage is chart position (#190 vs unranked) and ratings volume (6 vs 1). On rating, ads, in-app purchases and device support there is nothing between them.
