Verdict
The clearest difference is in-app purchases: Biological Buffer Calculator at none against MyCat Pro's 1. Biological Buffer Calculator also leads on iOS requirement (8.0 vs 18.0). MyCat Pro's advantage is update cadence (every 6 months vs every 77 months). On price, ads and device support there is nothing between them.
