Verdict
The clearest difference is ads: HiDuck at none against TutorMundi's shown. HiDuck also leads on update cadence (every 10 days vs every 4 weeks). TutorMundi's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price and in-app purchases there is nothing between them.
