Verdict
The clearest difference is in-app purchases: Fourier Series Visualiser at none against Physics Questions's 9. Fourier Series Visualiser also leads on ads (none vs shown). Physics Questions's advantage is update cadence (every 4 days vs every 11 months) and iOS requirement (12.0 vs 26.0). On price and device support there is nothing between them.
