Verdict
The clearest difference is rating: UMU at 4.9 against RainClassroom's 1.3. UMU also leads on review sentiment (57% vs 39%) and update cadence (fortnightly vs every 2 months). RainClassroom's advantage is in-app purchases (none vs 1). On price, ads, device support and iOS requirement there is nothing between them.
