Curve Fit Graph Calc Lite 4.3

The iCurve Fitter & iMulti Fitter applications represent some of the most advanced graph analysis tools available on the App Store, distinguished by their user-friendly interfaces. These tools serve as valuable resources for professionals such as physicians, engineers, students, and laboratory researchers. They facilitate the derivation of mathematical equations that best fit one or multiple sets of experimental data points, accommodating polynomials of any desired degree.

Utilizing sophisticated polynomial interpolation methods, these applications effectively plot data points and generate the corresponding fitted curves. Users can effortlessly input experimental data as pairs of (x, y) values, after which the application automatically constructs and displays the graphical representation on a Cartesian plane. The interface allows for interactive manipulation of the graph—including zooming, panning, and tracking—to enable precise analysis. This functionality supports determination of y-values at arbitrary x-values and evaluation of the curve’s slope at specific points.

A dedicated solver interface provides numerical outputs with high precision, while new features enable calculation and visualization of the area under a curve within specified intervals. The applications also afford access to derived equations and numerical results through exportable and shareable formatted sheets. Automatic identification and display of minima, maxima, and root points further enhance analytical capabilities.
