Verdict
The clearest difference is in-app purchases: Eyka at none against On the line's 1. Eyka also leads on update cadence (fortnightly vs every 4 months) and chart position (#123 vs unranked). On the line's advantage is ratings volume (140 vs 28) and iOS requirement (9.0 vs 15.0). On price, rating, review sentiment and ads there is nothing between them.
