About

Gompertz curve Calculator

Features
Read full description

A strong tool for software testing. Gompertz curve calculator can calculates Gompertz curve from 3-point times (t0, t1, t2) and values (A, B, C). Asymptote means the maximum or minimum value. When you enter an arbitrary time (tx), you know the value at tx (F(tx)). Gompertz model is representative of all biological growth (e.g. tumor growth). It is also used for software reliability growth model.

Verdict

The call

The clearest difference is in-app purchases: Gompertz curve Calculator at none against Polygon's 4. Gompertz curve Calculator also leads on iOS requirement (13.1 vs 17.0). Polygon's advantage is update cadence (weekly vs every 30 months). On price, ads and device support there is nothing between them.
