Verdict
The clearest difference is in-app purchases: Math Function Viewer at none against Ncalc's 4. Math Function Viewer also leads on ads (none vs shown) and iOS requirement (8.0 vs 15). Ncalc's advantage is update cadence (every 2 months vs every 6 months). On price and device support there is nothing between them.
