# LOK Digital vs Preserve™

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.

Both are free to download. LOK Digital sells 1 one-off in-app purchase and Preserve™ sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for LOK Digital against 4.7 for Preserve™. That said, the two scores are not equally well evidenced: Preserve™ has 1.2K ratings behind it against 167, so its average is the more settled of the two. Written reviews are what separate them: 83% of LOK Digital's written reviews are positive against 70% of Preserve™'s.

LOK Digital ships an update every 5 days, Preserve™ daily. Both last shipped on November 8, 2026.
