Verdict
The clearest difference is update cadence: Changemonitor at every 9 days against Pep Planner's every 2 months. Changemonitor also leads on review sentiment (14% vs 0%). Pep Planner's advantage is iOS requirement (15.0 vs 17.6). On price, ads, in-app purchases and monetization model there is nothing between them.
