Verdict
The clearest difference is rating: P.R.E.P. at 5.0 against Omnilert's 4.0. P.R.E.P. also leads on iOS requirement (13.0 vs 16.0). Omnilert's advantage is ratings volume (12 vs 1) and update cadence (every 2 months vs every 4 months). On price, ads, in-app purchases and monetization model there is nothing between them.
