Verdict
The clearest difference is ads: LOK Digital at none against Preserve™'s shown. LOK Digital also leads on review sentiment (83% vs 70%) and iOS requirement (13.0 vs 17.0). Preserve™'s advantage is update cadence (daily vs every 5 days) and ratings volume (1.2K vs 167). On price, rating, in-app purchases and monetization model there is nothing between them.
