Verdict

The call

The clearest difference is rating: Prepry at 4.6 against Mobile MIM's 3.1. Prepry also leads on review sentiment (89% vs 52%) and update cadence (fortnightly vs every 2 months). Mobile MIM's advantage is in-app purchases (none vs 5) and iOS requirement (12.0 vs 16.0). On price, ads and device support there is nothing between them.
