Verdict
The clearest difference is price: Frequency Analyzer at Free against ParaGraph3D's $0.99. Frequency Analyzer also leads on update cadence (every 8 days vs every 9 months). ParaGraph3D's advantage is in-app purchases (none vs 11). On ads, device support and iOS requirement there is nothing between them.
