Verdict
The clearest difference is rating: Cardiac MRI Guide at 5.0 against MRI MASTER's 4.5. Cardiac MRI Guide also leads on in-app purchases (none vs 1) and update cadence (every 2 weeks vs every 2 months). MRI MASTER's advantage is ratings volume (50 vs 2). On price, ads, device support and iOS requirement there is nothing between them.
