Verdict
The clearest difference is in-app purchases: FFMI Calc at none against FFMI Analyzer's 3. FFMI Calc also leads on iOS requirement (17.0 vs 26.2). FFMI Analyzer's advantage is update cadence (every 2 days vs every 4 weeks) and device support (3 vs 1). On price and ads there is nothing between them.
