Graphulator boasts being the only calculator which can perform calculus on non-functions numerically (equations which cannot be reduced to a function). It should be noted that these derivatives differ from standard calculus. Graphulator boasts being the only numerical calculator which can plot three variable non-functions. (Equations of the form f(xyz) = f(xyz)). If you believe either of these claims to be untrue, let us know (contact@Graphulator.com).

Verdict
The clearest difference is in-app purchases: Graphulator With Calculus at none against Stopwatch Library's 1. Graphulator With Calculus also leads on iOS requirement (8.0 vs 17.0). Stopwatch Library's advantage is update cadence (every 3 days vs every 2 months). On price, ads and device support there is nothing between them.
